If you just want a good dz to jump at, (without beach landing) i would say Skydive Ramblers Toogoolawah. Did my AFF there, really good place and really friendly people around the dz. And Kangaroos in the landing area
I did a gear rental on a icon with a pilot 168 for 30 days for 530 AUD at MEE LOFT in Brisbane. Koppel that runs the loft is a really nice guy that will help you with everything you need.
And Skydive Rablers is about a 1.5 h drive from Brisbane.
Have fun mate
