Mate,
I've always found it harder going this time of year.
Rather than fish out the front, I'd consider giving Theodolite a go. You can get almost to the creek's edge in your 4wd. If you can get your hands on some livies, fish for flatties. You can also do the same up the other end at the mouth of the Burrum, near the boat ramp. I reckon you may have more luck in the creeks than out the front right now.
Also try for whiting on the bend of the beach (mouth of the Burrum) with worms if you can get some. You can drive right around there.
