Gday Burnsy and Roberta, thanks for your reply. I have a feeling that joining this site was a wise move towards making me a better fisho so cheers.
I have realised what I did wrong. I was fishing too shallow with a plastic stopper that hits on the top runner, therefore my stopper-bottom hook distance was about a rod length (6'6" for me). Next time I will use a stopper knot and find bottom, then come up from there. My other rod is a 12 ft surf rod but its too heavy and stiff for this purpose.
As for the weed I plan to tie my hooks with a uni knot and leave a short tag where I will lay the centre of a length of weed. From there I will twist or plait down to the hook.
Next time I want to place 1 split shot right below the float and one about 20-30cm from the hook.
I have a 6 ft net which is just long enough with my short rod. Just have to be careful when it comes to landing.
Thanks for the tips and the photo. You'll be the first to know when I have success.
