capital gains and rental income in australia

Hello: I am currently in Canada but looking at the possibility of spending our winters in Australia as I have family there. This will be a few years away as I am still working here. In the meantime I am considering purchasing a rental property in Perth.
Can anyone tell me if I have to pay income tax to both the Australian and Canadian governments on the rental income of this property?? Also, what happens if I sell that property. Do I pay capital gains to both countries as well??
I have tried to understand the Australian-Canadian Tax Treaty but it's all too confusing.
Hoping someone has a straightforward answer to help me out.
Thanks
Marie:-)

You will be taxable in Australia forst on renatl and cap gains arising from your property in OZ.

You will also be taxable in canada on such income, with Canada giving credit for the OZ tax.
