I guy welcome in OZ
I've been in OZ for 6 months and for one more year. I come from Belgium and had the same issue than you when I arrived : the need to sail quickly, to buy a quiver and to store it ...
To buy my gear I used seabreeze forum and SHQ shop (large choice of second hand materal) and I could find nearly everything.
To store my gear (and the one of my wife) I became member of Elwood sailing club where you can sail and store gear in secure lockers but it's not free ... check
www.elwoodsc.com/blog/ To joint the club you'll need to be introduced by a member, I can do it for you . (colinet.herve@gmail.com)
Elwood is perfect for summer time, side shore seabreeze nearly everyday in avro, some funny waves and jumps. In winter you can catch the northerly at green point just next to Elwood because it's dead off-shore at Elwood club.
Good luck
