Western Rock Lobster
Offshore / ReefWA's iconic west-coast endemic crustacean and one of the most valuable single-species fisheries in Australia. Distributed along the west coast from around North West Cape down to Augusta, with the recreational fishery centred on the metropolitan and mid-west reefs from Mandurah to Kalbarri. Taken by pot or by free-dive only — no scuba, no hookah, no spears — and managed under a separate Recreational Rock Lobster Licence.
Western rock lobster (Panulirus cygnus) are endemic to WA's west coast, from approximately North West Cape down to Augusta. The recreational fishery runs from the metropolitan reefs at Rottnest, Garden Island and the Five Fathom Bank, through the mid-west grounds off Lancelin, Cervantes, Jurien Bay, Dongara and Geraldton, with juveniles and adults moving between inshore reef in 5–20m and offshore reef out to 100m. The commercial fishery is one of the largest single-species fisheries in Australia and runs alongside the rec sector under a strict Total Allowable Catch model. For recreational fishers it's a licensed, gear-restricted activity — pot or free-dive only — and a Perth summer institution. The first weekend of season opening sees the western suburbs ramps move every tinnie and dive boat in the city out to the inshore reefs.

Not applicable — rock lobster are not taken on lures or rod and line
Pot or free-dive only. Each licence holder is permitted up to 2 pots, and pots must be tagged with the licence holder's details and meet DPIRD construction rules (single entrance, neck size restrictions, escape gaps). Diving is by hand, blunt crook, or hand-held snare — nets and spears are illegal. Scuba and hookah are not permitted for taking western rock lobster; the rec fishery is free-dive only. Lobsters must be measured in the water before they leave the reef.
Pot fishing is the dominant rec method — drop pots on rubbly reef edges in 10–40m, leave them overnight or for a working day, and lift on the return. Bait the basket heavily and use a pot float rated to the depth and current. Free-divers work shallow inshore reef, holding breath down to ledges and overhangs and easing a snare or gloved hand around the antennae before extracting the lobster cleanly. The annual tail-clip or tail-punch tagging requirement applies to every rec-caught lobster before it leaves the boat or beach. Recover, gauge, tag — every time.
South of North West Cape the season runs 15 October to 30 June; north of the Cape the fishery is open year-round. Inshore reefs fish best early in the season (October through January) before the migration moves lobsters out to deeper water. Diving conditions favour calm mornings on small swells; pot fishing is more weather-tolerant. A night fishing ban applies between North West Cape and Cape Leeuwin (7:30pm–4:30am from 15 October to 31 March, 6:00pm–6:00am from 1 April to 30 June).
Up to 5kg, commonly 400g–1.5kg; carapace 76–130mm
Oct 15 – Jun 30 (south of North West Cape); year-round north
Outstanding — sweet, firm, clean-flavoured tail meat that needs very little intervention. Plunge live into boiling salted water for 8–12 minutes depending on size, chill, then split and serve with lemon and butter. Split and grilled over coals with garlic butter is the other classic; the body shells make excellent stock or bisque base.
A separate Recreational Rock Lobster Licence is required (in addition to any other licences). Daily bag limit: 8 lobsters per licensed fisher. Boat possession: 8 with one licensed fisher aboard, 16 with two, capped at 24 with three or more. Minimum size: 76mm carapace, measured from the ridge between the two front spikes to the back of the carapace. Berried (egg-carrying) females and tar-spot lobsters must be returned to the water immediately. Maximum 2 pots per licence; pots must be tagged with the licence holder's details. Free-dive only — scuba and hookah are not permitted; collection is by hand, blunt crook or hand-held snare. Every lobster taken must be tagged by clipping the bottom half of the central tail-fan flap or punching a 10mm hole before leaving the water or boat. Always check current DPIRD rules — regulations may change.
Buy a registered lobster gauge and use it on every lobster in the water before it comes aboard — undersized possession fines are substantial and DPIRD compliance is active across the metropolitan and mid-west grounds through summer. Tag immediately; an untagged lobster on the boat is a problem regardless of size. Keep catch alive in a wet hessian sack rather than in a sealed bucket where they'll suffocate. Rottnest, Garden Island and the inshore reefs off Mindarie, Lancelin, Cervantes and Jurien Bay are the reliable rec grounds for boat-based pot work; the Marmion and Hillarys reefs hold dive lobsters early in the season.
