Club Linux Coffs Harbour

I attempted to use the 'AusKey Secure Identity Data Exchange Thingy' only to find it does not work with GNU/Linux. I emailed them to let them know about their broken system and just recieved this cut&paste response:

The AUSkey solution currently does not support the Linux platform. This is consistent with other ATO systems.  The 'technical information' link on the AUSkey site outlines the operating systems and browsers that are officially supported.
