Here's a few shots of my gear for mullet. They fight like heck for a short time.
Home tyed flies, made from yellow chenille and tied with D20 yellow cotton. You'll have to experiment with the hook size but I find the bigger the fish I see the bigger the hook I choose. Use a small hook and you'll only catch small mullet. It's as if they have a pecking order sometimes.
The technique that works best for us is simply to locate the school of mullet, spread bran over the surface (they go mad for this) and about 30 seconds later start casting. If the fly gets into the bran then just give it the occasional tug and the fish will do the rest. If it sinks, then just start again.
We've seen some gnarly blokes with grins as wide as their faces after they've been sceptical about this then try it out!
