Hi Zen_Grrl
I'd be really interested in doing some mountain-biking in Brisbane as well. I'm also living in the UK and have been here for 5 years. I've got into cycling in the last year and have done a little bit of off-road, but really want to get into mountain-biking when I get to to Oz. I've mainly just been commuting and now do a bit of touring.
Let me know how you get on.
