​Measuring rock lobster

The length of the rock lobster's​ carapace (shell) is used to measure its size. To measure a rock lobster:
  • Spread the antennal horns.
  • Place the gauge tip hard into the middle notch.
  • Measure from the notch to the end of the carapace.
If you are taking rock lobster close to minimum size, be sure your measuring device is accurate.




Tail-marking rock lobster

​Rock lobster that you keep must be marked as recreationally-caught:
  • Southern Zone: Cut off at least a quarter of the central tail fan segment OR punch a 10 mm hole in it.
  • Northern Zone: Cut off at least a quarter of both outer tail fan segments OR punch a 10mm hole in them..
If fishing from a boat, mark the tail fan within 5 minutes of the lobster being brought to the boat, before retrieving another pot, moving the boat, and before landing.

If fishing from the shore, mark the tail fan within 5 minutes of landing and within 50 metres of where you are fishing.
