Any unicyclists in Adelaide and/or Canberra?

[Yeti]

I will travel to Australia early March for business. Probably I will fly in to Adelaide at March 5 or 6, staying there until March 9. Over the weekend I will proceed to Canberra, where I'll stay until March 14 or 15. The trip is not yet finally approved. But it is very likely it will happen.
Are there any unicyclists in Adelaide or Canberra who would take me for a ride? I am open for any kind of unicycle riding, where I am a complete newbie to trial and street. My favorites are touring/XC, freestyle, muni. But I am also happy to play basket ball or hockey.
I will bring equipment like helmet, gloves, ..., but I cannot bring a unicycle. So I would need to borrow one. I am a pretty tall guy (1,92m) with a crotch length of 98cm (sorry American fellows, this is addressed to the Aussies, and they use meters and centimeters). If needed I can bring a long seat post.
Looking forward to ride with you in Down Under
