Hi,

Congrats with your move to Canada! I'm hoping to go there next year! Did you find it easy to find a job and settle in?

With regards to your question, I think the best bet is to consult the Australian Tax Accountant. I assume you were working the whole Australian financial year up to May. Also it depends on your declaration on being domicile/non resident etc etc. As Auld Yin mentioned, if you have investment property etc its best to hire someone. It's even more complicated!

You can also go to the ato website which has some information:

You are correct to have concerns about the tax ramifications as the Australian government has made changes to the 2009/2010 budgets with regards to foreign income rules. This may affect you next year if you are on a working holiday. Here's some info

Hope this helps a little bit.
