Thats a very long strech of beach you are talking about. I have been getting fish along the beaches recently. They should fish well providing the weather is respectable. Depends what sort of fish you are targeting.
Dart will be everywhere.
Bream, near rocky beaches would be the best bet.
tailor aren't in good numbers in QLd.
whiting are everywhere.
I suggest you find out a bit about the fish on the beaches and which ones you will target, then go about finding places that might hold them
cheers
