Estuarys -Flathead
Large rivers - Jewfish
Beaches - Tailor
Fresh - Cod
Bay - snapper
Don't do any fishing outside.
Overall I would say Flathead because you don't really have to know an area , you don't need a lot of gear, you can just pull up on the side of the road near a spot grab the spin rod out the back and have a flick in most Australian tidal estuary's, rivers and Beaches.
They take many baits live, frozen or fresh cut-baits,they take many HB lures, many shapes size and colour plastics.
They release well and the are also quite nice in the pan.
*You need to add Flathead to the poll.
