Mate if you read some of Craig’s reports on live baits he explains why, where and how he go’s about getting them.
I just park under the Sundale bridge on the last of the run in and 1 or 2 hrs of the run out and get them around the pylons. I use a small SP lure, fling it as hard as I can, count to 5 then a slow steady retrieve. As it makes its way back up thru the water column is when you’ll get them.
This method will also get you a lot of small tailor but be careful of the size, remember tailor = 35cm. lately fisheries have been out and about checking everything..
I don’t know if there are a lot of differences between nsw and qld as far as boating rules but read up on them and size and bag limits are also different.
