Where is the best beach fishing north of the river? I live in joondalup but I dont mind driving.

I plan on using gang hooks with mulies for bait.

I'm not sure if I should use a sinker and let the bait sit on the bottom or go sinker-less and slowly real in the bait like a fish swimming. Whats best?

What kind of fish will I catch using that set up?

The more info you can give me the better as im pretty new to fishing!

Thanks!
