Leaving Australia

This is where it gets interesting and a little scary

Getting out of Australia, but still remaining on the ground might prove to be impossible.
There are rumours that the Barge from Darwin to Timor still accepts passenger traffic, other than this the only other route is by 'unofficial' means from Saibai Islands to PNG or by one of the expensive freighters out of Cairns, Darwin or even Perth.

As of June 11 2008:

Perkins operate the MV Arafura Endeavour and CEC Venture, Ro-Ro's out of Darwin, they take 4x4's over for about $110

FREQ: ~1 a week

TIME: Around 12 Hours (700km)
