Dylan,
I am guessing when you bait fish you are anchored up and fishing with the current? How are you fishing with lures - I mean are you anchored up or moving around in the boat? I know you don't really have an income, but a bow mount electric motor makes it so much easier to fish lures
My mate is a good Bream lure fisho (fishes a few of the local tournaments) and he fishes the Nerang too - sounds like a similar area to you (he is around the Sorrento area). Maybe we can try to catch you on the water one day and he can give you a few tips?
It would just be a case of both being on the water at the same time - he mainly fishes Sundays.
