There are a few down your way , i know there was Andrew and Graham
Andy was in sydney i think and grey is in Katoomba.
Both are on this forum as members so you can mail, that shouldn't be a probs.
It is pretty good fun but it can be intense. I am older myself and just really need to dedicate alot of time which i don't really have. It is less hassle for me at the moment to go for a skate anytime anywhere with no preperation. Jumping stilts can be a bit of logistical pain in the arrrrs.
good ............but not many around together so makes it a little boring as most of us with bocks end up bouncing around on your own./
There is a couple of links at the links page .
Grayham is at the wieder the better webstore.
Andrew is the Bock shop
Greg is skyrunners
If you looking for an intro on bocks , maybe with the good aussie $ , you could even try the 7's from england/germany. Power skips are at the high end of the market.
Whatever you choose, they will all give you a good idea if you like it or not.
There are many things with it, like when you first start your muscles in your back will start to ache bad as if you will not ever walk again, but once you get over this you will enjoy more.
