As a general rule, if you are fishing from rocks exposed to ocean swell in a declared area, then you will need to wear a lifejacket. It is safest to wear a lifejacket whenever and wherever you are rock fishing.
Above: The Randwick Local Governement Area showing the declared areas where a lifejacket ust be worn.
Some lifejackets approved under other standards may also meet the requirements.
