Ok, in most estuarys the above is true. Generally you will not need a license if fishing for sal****er fish that are visiting such as bass and mullet. Bear in mind that any bass here are likely to be schoolie bass and are thus undersize (current regs are 40cm afaik), though they provide good catch and release sport. If you are targetting freshwater fish that stray down there then you will probably need a license. Either way, some angling clubs have the fishing rights for these areas and so you'll need a permit off them whether you need a license or not. Again, check with local tackle shops, and if you buy something worthwhile, you might pick up some good tackle/bait/spot advice from them...
