im not sure which site you are after, so i have included to links that may help.
I should mention I am an aussie, and if you are able to watch it, please do so as it gets quite dramatic.
the first link is to the official site
http://www.thebiggestloser.com.au/
and this link is to the australian unofficial forum
http://the-biggest-loser.com.au/phpbb/index.php
hope this helps
