Another quick search found this from Marion council

subject to the Native Vegetation Act 1991 and the National Parks and Wildlife Act
1972 –
2.15.1 damage, pick, or interfere with any plant or flower thereon; or
2.15.2 tease, or cause harm to any animal, bird or marine creature.
Not quite as specific but leaving a carp dead on the side of a bank while you carry on fishing should cover off..
To cut it short.. basically the council has the power to ask you to move on. They will send someone out to ask you to move on. This person will quote the by-law and if you don't move on they will call the police. I know this as I have been asked to move on from a spot before !
