never done any beach fishing as such at Caloundra, but (and without trying to play down what you are doing) I think you are going to try to catch too much in a short time, you are aiming at the top with the Jewfish and then Flathead and everything in between! I think i would set my sights just a bit lower and be just a tad more specific. Target what will be plentiful at that time, and reasonably easy to catch, then as time passes, you can work your way up the "ladder" to add other species to you bag, one step at a time.
