Legislation has changed, this option is no longer available. It is much more strict now. I think from memory you now have evidence of living in (and working) that country for a minimum of 2 years, eg. evidence is rental agreement etc. Read the ATO for more info. on the new legislation, offshore oil & gas workers earning a hefty income are the ones being targeted hear.
