Offshore Fishing in Western Australia: Best Spots, Safety Tips, and Tides

Explore WA’s World-Class Offshore Fishing

Western Australia’s offshore waters offer some of the most exciting sportfishing opportunities anywhere in the world. From deep reef systems teeming with demersal species to the bluewater playgrounds where marlin, tuna, and mackerel roam, there’s something for every boat angler. In this guide, we uncover WA’s top offshore fishing destinations, essential gear for heading out to sea, safety considerations, and expert tips for landing your dream catch.



Why Offshore Fishing in WA is Special

Western Australia’s offshore waters are a true angler’s playground — vast, rugged, and brimming with life. From just a few kilometers out to the deep continental shelf drop-offs, WA offers access to some of the richest fisheries in the world.

Chasing iconic species like dhufish, pink snapper, baldchin groper, Spanish mackerel, yellowfin tuna, and even marlin becomes part of the offshore adventure. Every trip holds the potential for a once-in-a-lifetime catch.

The diversity across regions is unmatched: metro boaters can target big snapper and Samson fish close to shore, while those heading north towards Exmouth and the Kimberley find vibrant coral reefs and pelagic action in warm tropical waters. With breathtaking scenery, clear blue oceans, and adrenaline-pumping fishing, WA offshore adventures are hard to beat.

Top Offshore Fishing Regions in WA

Perth Metro Offshore (Cockburn Sound to Rottnest Island)

Just a short run from Perth’s boat ramps, anglers can access deep reefs, drop-offs, and wrecks that hold quality demersal species. Snapper, dhufish, baldchin groper, and Samson fish are common targets. Calm winter days often offer the best conditions for offshore launches in the metro area.

  • Best For: Beginners to intermediate anglers wanting reliable offshore action close to shore.
  • Species: Pink snapper, dhufish, Samson fish, baldchin groper, skippy.
  • Tip: Fish near reef edges and structure during low-light periods for snapper — pre-dawn bite windows are especially productive.
  • When to Go: Best from late autumn to early spring, especially after storms stir up the inshore waters.

Abrolhos Islands (Geraldton Offshore)

A dream destination for offshore fishing, the Abrolhos Islands offer sheltered anchorages, vibrant coral reefs, and thick schools of trophy fish. The variety is staggering — from coral trout to Spanish mackerel and big baldchin groper. Access is typically by larger private boats or charter.

  • Best For: Experienced anglers and charter trips seeking mixed reef and pelagic action.
  • Species: Coral trout, baldchin groper, dhufish, Spanish mackerel, spangled emperor.
  • Tip: Troll lures around island drop-offs early morning for Spanish mackerel before switching to jigging or bait fishing the reefs.
  • When to Go: Best during autumn (March–May) when weather windows are more stable.

Exmouth Offshore

Exmouth offers a world-class offshore fishery just minutes from shore. You can target reef species on one trip and head out for billfish the next. The Ningaloo Reef drop-off brings sailfish, marlin, tuna, and mahi-mahi within easy reach for trailer boats.

  • Best For: Serious game fishers and offshore adventurers.
  • Species: Black marlin, sailfish, yellowfin tuna, wahoo, coral trout, red emperor.
  • Tip: Keep a rigged pitch bait ready when trolling — free-swimming sailfish and marlin often appear near the boat.
  • When to Go: Peak game fishing season is March to July; reef fishing is productive year-round.

Dampier Archipelago (Karratha Offshore)

The Dampier Archipelago boasts hundreds of islands and hidden reef systems, creating endless fishing options. Target pelagics offshore or drop deep for huge red emperor and coral trout. It’s a rugged, remote paradise for adventurous anglers.

  • Best For: Experienced offshore crews and well-equipped boats.
  • Species: Red emperor, coral trout, Spanish mackerel, longtail tuna, cobia.
  • Tip: Drift fishing over isolated reef bommies often produces the biggest fish — look for sharp drop-offs on the sounder.
  • When to Go: Best from late autumn to early spring when cyclone activity is low.

Broome Offshore

Offshore Broome offers seasonal encounters with sailfish, black marlin, tuna, and Spanish mackerel. The billfish season brings explosive surface action, while reef fishing for golden snapper and cod is also productive along the coast.

  • Best For: Billfish chasers and pelagic hunters.
  • Species: Sailfish, black marlin, Spanish mackerel, golden snapper, bluebone.
  • Tip: Watch for bait balls and bird activity offshore — billfish often aren’t far behind.
  • When to Go: Peak sailfish season runs from June to September.

Essential Gear and Safety Tips for Offshore Fishing in WA

Offshore fishing demands a serious step up in gear and preparation compared to land-based or estuary fishing. You’re often targeting bigger, stronger fish — and once you’re offshore, conditions can change quickly. Having the right tackle and a sharp focus on safety is critical to a successful and stress-free day at sea.

Here’s what you’ll need to fish offshore confidently and safely:

Offshore Fishing with Coastal Fishing Guide

Essential Gear

  • Heavy-Duty Rod and Reel Combos
    (15–30 lb setups for reef species; 30–80 lb gear for big pelagics like marlin and tuna.)
  • Braided Main Line with Tough Leaders
    (30–80 lb braid with appropriate fluorocarbon or mono leaders for abrasion resistance.)
  • Deep Drop Jigs and Bait Rigs
    (For reef fishing in 30+ metre depths — paternoster rigs, heavy jigs, live bait setups.)
  • Trolling Gear
    (Game rods, outriggers, trolling lures for mackerel, wahoo, sailfish, and marlin.)
  • Gimbal Belt and Fighting Harness
    (Essential when fighting big fish offshore.)
  • Heavy Landing Net or Gaff
    (For safely landing big reef and pelagic species.)
  • Sounder/GPS Combo
    (Critical for finding offshore reefs, ledges, and navigating safely.)
  • Ice Slurry or Kill Tank
    (Keep your catch in premium condition — especially valuable reef species.)

⚠️ Safety Tips

  • Mandatory Safety Gear
    (EPIRB, flares, lifejackets, VHF radio — check requirements before every trip.)
  • Weather Planning
    (Always monitor forecasts — offshore conditions can deteriorate rapidly.)
  • Fuel and Range Management
    (Plan to use no more than one-third of your fuel outbound; one-third for return; and reserve one-third for safety.)
  • Buddy Systems
    (Whenever possible, fish offshore with at least two boats, or advise someone reliable of your departure and return times.)
  • Sun Protection and Hydration
    (Long days offshore mean hats, sunscreen, protective clothing, and plenty of water.)

💡Pro Tip

Maximise your chances by focusing on low-light periods and tidal changes.
Many offshore predators feed most aggressively around dawn, dusk, and during major tidal shifts. Plan your runs to have baits in the water just before first light or near peak tide changes. Whether you’re trolling for pelagics or bottom-fishing reefs, these windows often produce your best action — especially when combined with bait schools and active birdlife.

Top Tips for Offshore Fishing Success in WA

Offshore fishing rewards preparation, smart tactics, and a bit of patience. Here are five top tips to help you get the most out of your offshore adventures:

Tip 1: Respect Offshore Weather

If in doubt, don’t go out. Small changes in wind offshore can create dangerous conditions quickly.

Tip 2: Use Your Sounder Properly

(Spend time sounding around — good structure often holds better fish than random drifting.)

Tip 3: Fish the Pressure Points

(Target up-current sides of reefs, bombies, and drop-offs where predators wait for food.)

Tip 4: Mix Your Tactics

(Troll, jig, bait-fish — adapting to conditions and species will produce more consistent results.)

Tip 5: Keep a Pitch Bait Ready

(Have a live bait or rigged bait ready to throw at free-swimming marlin, tuna, or cobia that appear unexpectedly.)

💡Pro Tip

Always look for life before you start fishing — no bait, no birds, no fish.
When you’re offshore, signs like bait schools, birds diving, dolphins working the surface, or surface boils often mean predators are nearby. If an area looks lifeless on the sounder and above water, don’t waste time — keep moving until you find the signs. Successful offshore anglers fish where the fish are, not where they hope they’ll be.

When to Fish Offshore in WA

Western Australia’s offshore fishing opportunities run year-round, but the best times often depend on the region, target species, and seasonal weather patterns. Understanding when to go can make a huge difference to your success (and your safety).

Here’s a quick guide:


  • Autumn (March–May):
    Some of the best offshore fishing conditions statewide. Light winds, stable weather, and active reef species like dhufish, snapper, and coral trout. Also prime time for Spanish mackerel and early-season billfish in the north.
  • Winter (June–August):
    Reef fishing remains strong in many southern and central areas. Big pink snapper fire up after winter storms near Perth. Pelagic action slows in the north, but bottom fishing stays consistent.
  • Spring (September–November):
    Rising water temperatures bring mackerel and tuna closer to shore again. Weather windows start improving in the north, and Exmouth’s billfish season ramps up.
  • Summer (December–February):
    Northern regions (Exmouth, Broome, Dampier) come alive with marlin, sailfish, and tropical pelagics. However, the risk of cyclones increases, and southern WA sees rougher offshore conditions — plan trips carefully.
