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.

Just a short run from Perth’s boat ramps, anglers can access deep reefs, drop-offs and wrecks holding 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 reef edges and structure during low-light periods for snapper — pre-dawn bite windows are especially productive.
  • When to Go: 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.

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 & Reel Combos: 15–30 lb setups for reef species; 30–80 lb gear for big pelagics such as marlin and tuna.
  • Braided Main Line with Tough Leaders: 30–80 lb braid matched to fluorocarbon or mono leaders for abrasion resistance.
  • Deep-Drop Jigs & Bait Rigs: Paternoster rigs, heavy jigs and live-bait setups for fishing reefs in 30 m + depths.
  • Trolling Gear: Game rods, outriggers and trolling lures for mackerel, wahoo, sailfish and marlin.
  • Gimbal Belt & Fighting Harness: Essential when battling big offshore fish.
  • Heavy Landing Net or Gaff: For safely landing large reef and pelagic species.
  • Sounder / GPS Combo: Critical for locating offshore reefs and ledges and for safe navigation.
  • Ice Slurry or Kill Tank: Keep your catch in premium condition — especially valuable reef species.

Safety Tips

  • Mandatory Safety Gear: EPIRB, flares, life-jackets and VHF radio — confirm compliance before every trip.
  • Weather Planning: Continuously monitor forecasts; offshore conditions can deteriorate rapidly.
  • Fuel & Range Management: Follow the ⅓-out, ⅓-back, ⅓-reserve rule to ensure a safe return.
  • Buddy System: Whenever possible fish offshore with at least two boats, or notify a reliable contact of your departure and return times.
  • Sun Protection & Hydration: Long days offshore demand hats, sunscreen, protective clothing and ample 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

Estuary fishing rewards anglers who pay attention to the little details. Whether you’re working a jetty, a winding river or a wide coastal inlet, these simple tips can help turn an average session into a standout one:

Tip 1: Fish the Structure

Target submerged trees, rock walls, jetties and channel edges where fish shelter and ambush prey.

Tip 2: Time Your Sessions with the Tides

Focus on the last two hours of the outgoing tide and the first hour of the incoming tide — baitfish move and predators follow.

Tip 3: Use Light Tackle for Finesse

When chasing bream or whiting in clear water, scale down to light leaders and small lures for more strikes.

Tip 4: Mix Up Your Lure Techniques

Vary retrieve speeds and styles: slow hops for bream, faster burns for flathead or tailor.

Tip 5: Move and Cover Water

If you’re not getting bites, keep moving — work different banks, depths and structures.

Tip 6: Watch for Bird Activity

Diving birds, jumping baitfish or surface boils often reveal where predators are hunting.

💡 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.
