Hi Kevin,
I'm also from Perth and now living in Wynnum. Theres a local spot in Manly which isn't the best but works if you're short on time and can't be bothered driving.
I've been out jumpinpin too, its a good spot but a bit scary if you're the only one there, send me a message if you're keen to go out there.
Same to you Ryan, send me a message if you want someone to go out to the pin with, I also have my own small boat.
Cheers.
