Southern Insight are the aussie distributors for Ram Mounts:
http://www.ram-mount.com.au/
I just had a look, and I couldn't find the Go Pro mount on their site
. I'm sure I bought one of my gopro ram mounts from them.
But if you search eBay for "GoPro Ram Mount" you'll find all sorts of options from just the GoPro to Ram ball up to full systems. The GoPro Ram Ball is about $8-10 if you already have a ram mount, or the whole setup will cost about the $50 mark.
