Geocaching Australia

Just wondering if any Aussi GeoCachers have used the GeoTeaming service promoted on the geocaching.com site?

I contacted them, to get info regarding a Team Building event for my workplace, aside from the cost per person ($75 - $195 pp) it will also be a minimum cost of $6k + T&E ?? !!!

Is there anywhere in Australia where a similar event can be organised that anyone is aware of??

I would love to do this as a Team Building exercise for my work, and know that a lot of people would enjoy it, just by me chatting about my weekend finds.

Any info would be appreciated, as these costs seem to be rather exhauberant.

Thanks
