Spearfishing Australia: A Region-by-Region Guide to Game Fish, Seasons, Hazards, and Charters

Australia is one of the greatest spearfishing destinations on the planet. The coastline stretches over 22,000 miles, the water ranges from tropical to temperate, and the species diversity is unlike anything you'll find in the Northern Hemisphere. I'm Bret Whitman, and through SpearFactor I've connected with divers from every corner of Australia — each one convinced their region is the best. The truth is, they're all right. Every stretch of Australian coastline offers something completely different, and if you're planning a spearfishing trip Down Under, understanding how each region differs is the key to maximizing your time in the water.

This guide breaks down Australia's major spearfishing regions — Queensland, New South Wales, Victoria, South Australia, Western Australia, and the Northern Territory — with the top three game fish in each area, how to hunt them, when to go, what hazards to watch for, and who to call when you need a charter or local guide. Whether you're an Australian diver looking to explore a new coast or an international visitor planning the trip of a lifetime, this is your roadmap.

Queensland: Tropical Reefs and World-Class Pelagics

Queensland is home to the Great Barrier Reef — the largest coral reef system on Earth — and the spearfishing here is as good as it gets anywhere in the world. Warm tropical water, incredible visibility, and an absurd variety of reef and pelagic species make this a bucket-list destination for divers worldwide. Water temperatures range from 72 to 84 degrees Fahrenheit year-round, and visibility on the outer reef regularly exceeds 60 feet.

Top 3 Species: Coral Trout, Spanish Mackerel, and Red Emperor

Coral trout are the crown jewel of Queensland reef spearfishing. These brilliantly colored fish live on and around coral structure at depths of 10 to 100 feet. They're ambush predators — you'll find them tucked under ledges, in coral caves, and along drop-offs waiting for prey to swim past. The common coral trout averages 3 to 8 pounds but can push past 15. They're most active during the warmer months from October to March. Minimum size is 38cm and bag limits apply, so check Queensland Fisheries regulations for your specific zone. On the plate, coral trout is arguably the best-eating reef fish in Australia — firm, white, sweet flesh that's fantastic raw, grilled, or steamed.

Spanish mackerel are the top pelagic target in Queensland waters. These fish migrate south along the Queensland coast from April through September, following bait schools along the continental shelf. They're fast, aggressive, and can exceed 60 pounds. Divers typically encounter them in 30 to 80 feet of water over reef structure or along current lines. Use a 110 to 130cm speargun with a heavy shaft — Spanish mackerel are thin-bodied and a poorly placed shot can blow through without anchoring. Aim for the head or spine. They bleed heavily, so get them on the boat fast before sharks arrive.

Red emperor are a deep-reef trophy species found throughout Queensland's offshore reefs. These fish average 10 to 20 pounds and live on deep reef structure, rubble bottoms, and gravel beds at depths of 60 to over 400 feet. Most spearfishing encounters happen in the 60 to 100 foot range on the outer reef. Red emperor have a minimum size of 55cm and seasonal closures to protect spawning aggregations — check current dates before targeting them. They're prized table fish with firm, flaky white meat.

Queensland Hazards

The Great Barrier Reef is sharky water — grey reef sharks, whitetip reef sharks, and the occasional tiger shark are all part of the ecosystem. Kill your fish quickly using iki jime to minimize blood and vibrations, and tow your catch at least 20 meters behind you on a float line. Never keep fish on your body. Box jellyfish and Irukandji jellyfish are a serious hazard in Queensland's tropical waters from October through May. These are potentially lethal — wear a full lycra suit or stinger suit during stinger season. Stonefish are present on reef flats and can deliver an excruciatingly painful, potentially dangerous sting if stepped on. Watch where you put your feet and hands on the reef. Saltwater crocodiles are found in northern Queensland waterways, estuaries, and occasionally in open ocean near river mouths. Exercise extreme caution north of Townsville.

New South Wales: Where Tropical Meets Temperate

New South Wales sits at the crossroads of warm tropical currents from the north and cool temperate water from the south. This convergence creates extraordinary species diversity — you can encounter tropical fish and cold-water species on the same dive depending on the season and current conditions. The East Australian Current pushes warm water south past Sydney and beyond, bringing pelagic species within range of shore divers. Water temps range from about 62 degrees in winter to 75 in summer. Visibility varies from 15 to 60 feet depending on conditions, with the best clarity typically in late autumn and winter.

Top 3 Species: Yellowtail Kingfish, Snapper, and Mahi-Mahi

Yellowtail kingfish are the ultimate New South Wales game fish for divers. These powerful pelagics patrol rocky reefs, headlands, and offshore structure from Sydney north to the Solitary Islands and south to Jervis Bay. They range from schoolie-size fish of 5 to 10 pounds up to trophy specimens over 60 pounds. Kingfish are present year-round but peak from autumn through spring when water temps are cooler. They're found at depths of 20 to 100 feet, often cruising mid-water around bommies and reef edges. A 100 to 120cm gun is standard. Kingfish are wary and require patient stalking — dive to the bottom, tuck into structure, and wait for them to come to you.

Speared Kingfish

Snapper are one of the most popular reef fish targets in New South Wales. Australasian snapper are found over rocky reef, sand patches, and drop-offs at depths of 15 to 80 feet. They average 4 to 10 pounds but fish over 20 pounds are taken regularly. The best season runs from late autumn through winter when cooler water brings snapper into shallower, more accessible depths. They can be skittish, so a quiet approach and precise shot placement are essential. Minimum size is 30cm and bag limits apply.

Mahi-mahi push into New South Wales waters on the East Australian Current during the warmer months from December through April. These vibrant, fast-growing pelagics are found around floating debris, FADs, and current lines anywhere from 5 to 60 miles offshore. They're typically at or near the surface and can be attracted with flashers. Most fish run 10 to 30 pounds. A mid-range speargun in the 100 to 110cm range handles them well. Mahi-mahi are aggressive feeders and less boat-shy than many pelagics, making them an excellent target for divers building bluewater skills.

New South Wales Hazards

Sharks are a constant presence in New South Wales waters. Bull sharks patrol the harbor areas and river mouths, while grey nurse sharks congregate around rocky reefs and gutters — note that grey nurse sharks are critically endangered and protected, so give them space and never harass them. Great white sharks are present along the entire NSW coast, particularly around seal colonies. Strong currents and rip tides are a major hazard along the exposed coast, especially around headlands and points where the East Australian Current accelerates. Blue-ringed octopus are found in rock pools and on shallow reefs throughout New South Wales — their bite is potentially fatal, so never handle small octopus. Blue bottles (Portuguese man o' war) are common, especially when onshore winds push them to the beaches. They're painful but rarely dangerous.

New South Wales Charters and Contacts

Adreno Spearfishing maintains a comprehensive directory of New South Wales dive sites at adreno.com.au. For guided kingfish and pelagic trips out of Sydney, Fishabout Sydney (fishaboutsydney.com.au, 0412 918 127) and Sydney Sportfishing Adventures (sydneysportfishing.com.au) both offer offshore charters in the Sydney area. For the south coast, local dive shops in Jervis Bay and Narooma are good starting points for connecting with experienced local divers who know the reefs. The NSW spearfishing community is active on social media — Facebook groups like Spearfishing NSW are excellent for finding dive buddies and local intel.

Victoria: Cold Water, Big Rewards

Victoria is temperate-water spearfishing at its finest. The water is colder — 52 to 68 degrees Fahrenheit depending on season — and you'll need a 5 to 7mm wetsuit to stay comfortable. But what Victoria lacks in tropical warmth it makes up for in the quality and size of its game fish. Port Phillip Bay, the Mornington Peninsula, Wilsons Promontory, and the western coast around Portland all offer excellent diving. Visibility is generally 15 to 40 feet, with the best conditions in autumn and early winter.

Top 3 Species: Southern Bluefin Tuna, Yellowtail Kingfish, and Snapper

Southern bluefin tuna are the ultimate Victorian pelagic.

These fish migrate through Bass Strait and along the Victorian coast during summer, from December through March. They average 40 to 80 pounds with fish over 100 pounds possible. Bluefin are found in open water along temperature breaks and current edges, typically 10 to 40 miles offshore. Full bluewater gear is required — a 60-plus-inch gun with multiple bands, heavy shaft with slip tip, and a breakaway float rig. Southern bluefin tuna are internationally managed and heavily regulated — check current bag limits and size restrictions carefully before targeting them.

Yellowtail kingfish are found in Victorian waters from late spring through autumn, especially around offshore structure, oil rigs, and rocky reefs. The techniques mirror New South Wales — work the structure, be patient, and let the fish come to you. Port Phillip Heads and Wilsons Promontory are premier locations. Victorian kingfish tend to run large, with fish over 40 pounds relatively common.

Snapper are a bread-and-butter species in Victoria, especially in Port Phillip Bay where large aggregations form in autumn and winter. Fish over 15 pounds are common, and the bay provides relatively sheltered conditions compared to open-coast diving. Work rocky reef edges and sand-to-reef transitions at 15 to 50 feet. The cooler months from April through August are prime time.

Victoria Hazards

Cold water is the primary hazard in Victoria. Hypothermia is a real risk, especially during winter dives when water drops into the low 50s. Wear adequate thermal protection and know your limits. The entrance to Port Phillip Bay at the Rip is one of the most dangerous stretches of water in Australia — tidal currents can exceed 6 knots, and the combination of current, swell, and shallow reef has claimed boats and lives. Only experienced divers with local knowledge should dive the Heads. Great white sharks are present in Victorian waters, particularly around seal colonies at Wilsons Promontory and the western coast.

Blue-ringed octopus are found on shallow reefs and in rock pools. Strong southerly swells can create dangerous surge conditions on exposed coastline.

Victoria Charters and Contacts

The Dive Spearfishing Tours (through Hoookn Adventures at hoookn.com.au) offers guided spearfishing trips with experienced local guides who specialize in Victorian species including kingfish and snapper. Their guides have over 15 years of local spearfishing experience.

Melbourne's spearfishing community is tight-knit and welcoming to visitors — connect through the Victorian Spearfishing Facebook groups for local advice and dive partners.

South Australia: Southern Ocean Giants

South Australia offers some of the most underrated spearfishing on the continent. The Spencer Gulf, Gulf St Vincent, and the exposed southern coastline along the Great Australian Bight provide diverse environments. Water temperatures range from 54 to 72 degrees, and the southern coastline can be rough and exposed, but the fish make it worth the effort. Visibility is generally excellent — 30 to 60 feet in the gulfs and often better on the open coast.

Top 3 Species: Southern Bluefin Tuna, Snapper, and Yellowtail Kingfish

Southern bluefin tuna are arguably South Australia's premier spearfishing target. Port Lincoln and the waters around the Spencer Gulf are internationally renowned for bluefin. The fish migrate through from December to April, and South Australian waters consistently produce some of the largest southern bluefin in the world. The same bluewater gear requirements apply as in Victoria — this is a serious, advanced-level pursuit that demands a full breakaway rig and team coordination.

Snapper are abundant in both gulfs, with fish migrating into shallower water during the cooler months. South Australian snapper are known for their size — fish over 20 pounds are caught regularly, and specimens over 30 pounds are possible. Target them over reef and rubble at 20 to 60 feet during autumn and winter. The Spencer Gulf in particular produces trophy-class snapper that rival any in the country.

Yellowtail kingfish patrol the structure-rich waters around Kangaroo Island, the Althorpe Islands, and along the Spencer Gulf during the warmer months. They run large in South Australian waters, with 30-plus-pound fish a realistic target. The exposed, current-swept coastline creates ideal kingfish habitat with plenty of structure and bait concentration.

South Australia Hazards

Great white sharks are a significant presence in South Australian waters. The Neptune Islands near Port Lincoln are one of the most famous great white aggregation sites in the world, and these animals patrol the surrounding coastline year-round. Exercise extreme caution, dive with a buddy at all times, and get fish out of the water quickly. Cold water is a constant factor — the Southern Ocean influence keeps temps low even in summer, and exposed coastline along the Bight can produce massive swells and dangerous surge. The gulfs are more sheltered but still experience strong tidal currents, particularly around narrow passages and reef entrances. Blue-ringed octopus are present on shallow reefs throughout the state.

South Australia Charters and Contacts

South Australia's spearfishing scene is smaller than Queensland or New South Wales, but the local community is knowledgeable and passionate. Port Lincoln is the hub for southern bluefin charters during summer — several operators run offshore trips during the tuna season. Check FishingBooker.com for current listings and availability. Adelaide-based dive shops can connect you with local spearfishing groups and shore diving guides for the Spencer Gulf and Gulf St Vincent. The South Australian Spearfishing Club is active and a great resource for visiting divers looking for local knowledge and dive partners.

Western Australia: From Ningaloo to the Southern Reefs

Western Australia has the longest coastline of any Australian state, and the spearfishing ranges from world-class tropical in the north to productive temperate water in the south. Ningaloo Reef near Exmouth is the crown jewel — a fringing reef that you can access straight from the beach, with warm, crystal-clear water and incredible species diversity. Water temps range from 68 degrees in the south to 84 in the tropical north. Visibility at Ningaloo regularly exceeds 60 feet.

Top 3 Species: Spanish Mackerel, Giant Trevally, and Coral Trout

Spanish mackerel are abundant off Western Australia's northern coast, especially around Ningaloo Reef and the Kimberley region. They arrive with the warming water in summer and autumn, from December through April, and can be found cruising reef edges and current lines at 15 to 60 feet. Ningaloo's shallow reef structure — often just 5 to 25 feet deep — means you can encounter Spanish mackerel in surprisingly shallow water. They're fast and hit hard, so a heavy shaft and solid shot placement behind the head are essential.

Giant trevally are the bulldogs of the reef. These powerful predators are found throughout northern Western Australia, particularly around Ningaloo, the Montebello Islands, and the Kimberley coast. They patrol reef edges, channels, and drop-offs at 10 to 80 feet, and they can exceed 100 pounds. Giant trevally are aggressive and will sometimes charge directly at a diver. Peak season is the warmer months from October through April. Use a heavy gun — 110cm minimum — because these fish fight brutally hard and will try to pull you into the reef.

Coral trout are found across Ningaloo and the northern reefs of Western Australia at depths of 5 to 60 feet. The reef structure at Ningaloo is shallow and accessible — many dives happen in just 10 to 25 feet of water. Note that coral trout regulations vary by zone in Western Australia, and some areas around Ningaloo Marine Park restrict the take of coral trout and tuskfish. Always check current DPIRD regulations for the specific zone you're diving.

Western Australia Hazards

Sharks are the number one hazard in Western Australia, and this is not an exaggeration. Western Australian waters have some of the highest shark encounter rates in the world. Tiger sharks, bull sharks, and great whites are all present depending on the region. At Ningaloo, reef sharks are everywhere and tiger sharks patrol the deeper edges. In the south around Perth and the southwest, great whites are a well-documented risk. Tow your catch far behind you, use iki jime immediately, get fish in the boat fast, and stay vigilant. Strong currents are a factor at Ningaloo, particularly on the outer reef edge where tidal exchange creates powerful flows that can sweep a diver off the reef and into deep water. Saltwater crocodiles are present in the Kimberley region of northern Western Australia. Sea snakes are common on the northern reefs but are generally docile unless provoked. Cone shells are found throughout the tropical reefs — their venom can be fatal, so never pick up live shells.

Western Australia Charters and Contacts

Ningaloo Reef near Exmouth is accessible from shore, but for the best offshore spots including the Muiron Islands, you'll want a boat or charter. Ningaloo Pearls (ningaloopearls.com.au) offers diving and fishing charters out of Exmouth. Ningaloo Blue (ningalooblue.com.au) is a privately owned charter operation with extensive local knowledge of the reef system. For the Perth and southwest region, Adreno Spearfishing (adreno.com.au) maintains a comprehensive directory of Western Australian dive sites and can point you toward local guides and charter operators. The Western Australian spearfishing community is active on social media and forums — connect through local groups for up-to-date site conditions and dive partners.

Northern Territory: Wild, Remote, and Full of Fish

The Northern Territory is Australia's last frontier for spearfishing. The Top End around Darwin and the Tiwi Islands offers warm, productive tropical water with species you won't find in the same concentrations anywhere else in the country. Water temperatures sit between 78 and 86 degrees year-round. Visibility is generally lower than Queensland or Western Australia — 10 to 30 feet is common — due to tidal influence and river runoff.

Top 3 Species: Spanish Mackerel, Longtail Tuna, and Golden Snapper

Spanish mackerel are the top pelagic in Northern Territory waters, migrating through from April to September during the dry season. They're found along reef edges, shoals, and current lines at depths of 15 to 50 feet. Heavy shaft, head or spine shot, and get the fish out of the water fast. Darwin Harbour and the offshore shoals north of the city are productive areas.

Longtail tuna are an exciting and accessible species unique to northern Australian waters. They school in shallow coastal water — sometimes just 5 to 15 feet deep — chasing bait along beaches, channels, and reef flats. They average 10 to 25 pounds and are incredibly fast. The best season is the dry season from May to October when water clarity improves. Longtail tuna are a great bluewater introduction species because they're often found in shallow, manageable conditions that don't require deep diving skills.

Golden snapper — also called fingermark — are a prized reef species throughout the Top End. They live around rocky reef, wrecks, and mangrove-adjacent structure at 15 to 80 feet. Golden snapper average 5 to 15 pounds and are excellent eating. They're present year-round but are most accessible during the dry season when visibility improves. Bag limits of 5 per person apply, with a minimum size of 40cm in the Northern Territory.

Northern Territory Hazards

Saltwater crocodiles are the dominant hazard in the Northern Territory, and this cannot be overstated. They are present in virtually every body of water — rivers, estuaries, harbors, and open ocean coastline. Crocodile attacks are not theoretical here; they happen regularly. Dive only in areas with established safety records, never dive near river mouths or mangrove-lined shorelines, and always consult local knowledge before entering any water. Box jellyfish and Irukandji are present during the wet season from October through May — full stinger suits are mandatory. Sharks are abundant, including bull sharks in turbid inshore waters where visibility is already poor. Sea snakes are common but generally non-aggressive. The massive tidal range in the Northern Territory — up to 8 meters in some areas — creates extremely strong currents that can change conditions dramatically within hours.

Planning Your Australian Spearfishing Trip

Australia's seasons are reversed from the Northern Hemisphere — summer runs December through February, and winter is June through August. This is critical for timing your trip. If you want tropical pelagics in Queensland, plan for the dry season from April to September. If you want southern bluefin in Victoria or South Australia, go during the southern summer from December to March. And if Ningaloo Reef is calling, the sweet spot is March through June when the water is warm, visibility is best, and the coral spawning event draws marine life from across the region.

Regulations vary significantly between states and territories. Every Australian state manages its own fisheries independently, with different bag limits, size restrictions, seasonal closures, and marine park zoning. Always check the relevant state fisheries authority before you dive — Queensland DAFF, NSW DPI, Victorian Fisheries, PIRSA in South Australia, DPIRD in Western Australia, and NT Fisheries in the Northern Territory. Fines for violations are steep and ignorance is not an accepted defense.

A few universal rules apply across Australia: spearfishing with scuba gear is illegal in every state. You must be freediving on breath-hold only. Spearguns cannot be loaded or carried within certain distances of swimmers and public beaches. And marine park zones — green zones in particular — are strictly no-take areas. Respect them.

Essential Safety for Diving in Australia

Australia's marine environment is beautiful but it demands respect. Between sharks, crocodiles, jellyfish, venomous marine life, strong currents, and cold water, the hazard list is longer than most places on Earth. That doesn't mean it's not worth diving — it absolutely is. But it means preparation and safety protocols are non-negotiable.

Never dive alone. Always carry a sharp knife accessible with either hand. Use iki jime to kill fish immediately and minimize blood in the water. Tow your catch well behind you on a float line — never attach fish to your body. Wear appropriate exposure protection for the region — stinger suits in the tropics, adequate neoprene in the south. Know the local hazards before you enter any new body of water, and when in doubt, ask a local.
