Bag Limits, Possession Limits & Legal Size Rules

What These Three Limits Actually Mean

Australian recreational fishing rules use three separate controls that work together. A bag limit is the maximum number of a species you may take in one day. A possession limit is the maximum you may have in your keeping at any time, including fish stored at home, in a freezer, in an esky or in a boat. A legal size limit sets the minimum, and sometimes maximum, length a fish must be before you may keep it. Fish outside the legal size range must be returned to the water with the least possible harm.

Limits differ by state and territory, by species, and sometimes by waterway. A snapper caught off Sydney is governed by New South Wales rules, while the same species taken in South Australian or Victorian waters may carry a different size and bag limit. Always check the current rules for the jurisdiction you are actually fishing in, not the one you live in.

Measuring Fish Correctly

Most Australian size limits are measured as total length, from the tip of the snout to the tip of the tail, with the tail squeezed together. Some species use different methods, so it pays to know which applies before you cast:

• Total length — used for the majority of finfish, including bream, flathead, whiting and mulloway.
• Fork length — snout to the fork of the tail, used for some tuna and pelagic species.
• Carapace length or width — used for crabs, lobsters and some crustaceans.
• Interdorsal length — applied to certain sharks in some jurisdictions.

Carry a rigid ruler or a measuring mat rather than relying on a marked rod butt. Measure the fish quickly while it is wet, keep it flat, and if it is borderline, release it. Fillets and headless fish are difficult or impossible to measure, which is why most states require fish to remain whole or in a measurable form until you reach your place of residence.

Combined and Grouped Limits

Several species are grouped under a shared limit. You might be allowed a certain number of a single species, but a lower combined total when mixing species from the same group, such as a combined limit across reef fish or across freshwater natives. There are also overall daily caps in some jurisdictions that apply no matter how many species you target.

Boat limits can apply as well. Where a boat limit exists, the vessel as a whole cannot exceed a set number of a species, even if every person aboard holds a valid licence and has not personally reached their individual bag limit.

Possession Limits at Home and in Transit

Possession limits are frequently misunderstood. Fishing hard for several days in a row does not allow you to accumulate unlimited fish. In most states the possession limit is a multiple of the daily bag limit, and it counts fish stored anywhere you control, including a home freezer. If you are travelling with a catch, keep it clearly separated by person where required and be ready to demonstrate that each fish is legal size.

• Keep fish whole or gilled and gutted where the rules allow, so length can still be verified.
• Do not mix your catch with another angler's in a single container if individual limits must be shown.
• Label frozen fish with the species and date caught as a simple record-keeping habit.
• Never give away or sell recreational catch — recreationally taken fish cannot be traded in Australia.

Zero Bag Limits and Protected Species

Some species carry a zero bag limit, meaning they must be released immediately regardless of size. Others are fully protected and may not be targeted at all. Before keeping anything unfamiliar, confirm its status — misidentification is one of the most common causes of accidental breaches. Our guide to protected species lists the fish, sharks, rays and invertebrates that must always be returned to the water.

Where Limits Change: Closures and Special Zones

Bag and size limits are not static. Spawning closures, temporary fishery restrictions and marine park zoning can reduce limits to zero for a period or ban fishing in an area entirely. Check the current seasonal closures before planning a trip, particularly for estuary species around Sydney and for freshwater natives, where closed seasons are common.

Practical Habits That Keep You Compliant

1. Check the official state fisheries rules for the exact water you are fishing, on the day you fish.
2. Carry a measuring device and an identification reference you can use offline.
3. Count your catch as it goes into the esky, not at the end of the session.
4. Release borderline and unwanted fish quickly, using wet hands and minimal air exposure.
5. Stop keeping fish once you reach the bag limit, even if you keep fishing catch-and-release.

Fisheries officers can inspect catch, gear and storage areas, and penalties apply for oversize, undersize and excess fish. Treating the limits as a firm ceiling rather than a target is the simplest way to fish legally and to leave enough fish in the water for next season.
