STATE FIGURES DIFFER AND FishRadar SHOWS THE STRICTEST WE HAVE VERIFIED. NSW: minimum 65 cm, 5 per day. Queensland: minimum 60 cm, 2 per person. Other states were not verified in this round. Kingfish is highly migratory and Commonwealth arrangements can apply beyond state waters.

Licensing:

saltwater-recreational — residents Licensing is state-level, not federal. NSW: the NSW Recreational Fishing Fee covers salt and fresh water. VIC: Victorian Recreational Fishing Licence. QLD: no general recreational licence for most saltwater fishing. WA, SA, TAS, NT: state-specific licences and permits. Bag, size and possession limits always come from the state you are fishing in., non-residents The same state rules apply to visitors, and a short-term licence can normally be bought online from the state authority before you fish.
freshwater-recreational — residents Inland fishing usually needs a state recreational licence (NSW, VIC) or an angler permit (NT, parts of QLD). Freshwater closed seasons are separate from tidal ones — Queensland, for example, closes barramundi in fresh water and in tidal water on the same dates but publishes them on different pages., non-residents Visiting anglers must hold the relevant state licence or permit.

FishRadar regulations are summaries for informational purposes only. Australian fishing rules are set by each state and vary by zone, and this national pack shows the strictest figure we have verified rather than your state's own. Always verify with the relevant state authority (NSW DPIRD, QLD DPI, VFA, WA DPIRD, SA PIRSA, NRE Tasmania, NT Fisheries) before fishing.
