Alex W, like most of the guys from brissie fish the eastern side of the highway from the Coomera boat ramp. Drew M also has a few videos from that area, search for his Coomera videos on YouTube.
Watch as many of John Costello's videos as you can. He's MyLureBox on YouTube, he gives you every bit of information you'll need and seems to enjoy teaching people how to catch them as much as he likes catching them. He does a bit of pontoon bashing around Broadbeach but a lot of his fishing is creek's around tweed and Currumbin. He has DVD's full of info and hundreds of hours of YouTube.
Early Timmy Turtle videos are awesome too, when he first started on his pipe skiff he was learning from scratch, you can watch all his mistakes and what he learnt along the way.
I've been heaps and yet to catch one, they aren't something you should expect to catch every session. I don't think any canal is rubbish, they seem to be in good numbers everywhere, you just have to throw what they want, where they want it and probably hold your tongue just right.
