G-day tommy
I don't know if you are land based or boating, estuary itself is on average around 2mtrs deep there is a channel that runs back to the ocean which from memory is about 6+mts deep which a land based fisho's could easily cast in to.how you actually get there I'm not sure,but if you go to the general store and have a chat with mark he will help you out with that. Another good land based place is Dolly's garden which you can access from a road opposite the caravan park. With your lures it's a bit of trial n error you just have to mix it up till you get something the bream will take. I had a lot of success with the vx35 in the olive color just drifting across the lake. If you are in a small tinnie make sure you check the wind forecast for the day, it can go from a mill pond to white caps in the blink of an eye. There is a storm hut on the other side of the lake near the entrance to the channel that you can take refuse in if you do get caught out. You'll get good variety of fish in the bemm and it's a really nice place to stay.
