Dont give up on Tally and Currumbin Creeks.
They dont fist at all well this time of year with all the boat traffic.
Early mornings and late at night well after the last boats have left is the best time to fish.
Early morning is worth a shot in the small Bay area in Tally Creek near the fenced off swimming area. Trevs and some decent Bream hunt the area. You will see the Trevs busting up.
On the turn of the tide when the water has slowed, walf the bank in either Creek leading to the mouth hopping small plastics or even drifting a pillie
I have not fished Currumbin much but there are still plenty of fish in Tally Creek
