From Australian Electoral Commission media release 24 August 2010:
The Australian Electoral Commission (AEC) is reminding all voters who cast a provisional vote on election day Saturday 21 August and didn't provide evidence of identity on the day, that they have until Friday 27 August to fulfil this requirement.
Electoral Commissioner, Ed Killesteyn said that voters may have cast a provisional vote on election day because their name or address could not be found on the list of voters or it appeared their name had already been marked off.
"The AEC must receive evidence of identity from provisional voters by 5pm on Friday 27 August 2010 or their vote cannot be counted," said Mr Killesteyn.
On election day a 'voter advice document' was provided to each voter who cast a provisional vote without providing an accepted form of identity. The document informed them of their obligation to provide evidence of their identity by this Friday.
These voters can visit an AEC office to show an accepted evidence of identity document or they can mail a photocopy of the document, provided it has been sighted and signed by an authorised person, to an AEC office.
Please note this requirement only applies to voters who cast a provisional vote on election day and did not provide evidence of identity on the day – and does not apply to any other voter.
Provisional votes are only counted after a careful check of enrolment records are made to confirm the provisional voter's eligibility.
