The Reserve Bank of Australia apparently has a policy on damaged notes, according to this article. So all may not be lost. "'If several pieces of the same banknote are presented, the Reserve Bank's policy is for each piece to be worth a share of the value in proportion to its size,' the RBA policy reads. If less than 20 per cent of the note is missing, full face value is paid, but if between 20-80 per cent of the note is missing, it is valued in proportion with the percentage remaining. If more than 80 per cent of the banknote is missing, no payment is made."
