Within the first 6 months of becoming a tax resident of Australia (and AFTER you are no longer a Canadian tax resident), pull out all of the (non locked-in) RRSP money, have the Canadian bank/investment company withhold 15% as per the tax treaty (make sure you tell them that you're a tax resident of Australia!), and there's no Australian tax implications, obligations are over and done with. You don't report any of it on a Canadian return as it is withdrawn when you are a non-resident and NR tax is already withheld.
If you wait until after 6 months, the difference between the value at the date you became a tax resident and the date it is liquidated will be taxable income in Australia. (e.g. if worth $60k at date of residency, and 65k at liquidation, you'll have 5k of taxable income in Australia).
It may also be subject to Australia's FIF rules and tax possibly payable on an annual basis (with additional accounting required to figure out the proper foreign tax credits).
If you have "locked-in" RSPs / LIRAs, it's not so easy to get the money out, depends on the federal or specific province rules that the account(s) need to follow (would be based on the pension where the locked-in account originated).
