If you are in Australia, you mail it to the address mentioned below, you can put your Australian bank account information on it but I am not sure it will be relevant as they CRA will most likely mail you a cheque, unless other arrangements have been made with them:
Sudbury Tax Centre

Sudbury ON P3A 5C2

Include one copy of each of your information slips with your return. These slips show the amount of income that was paid to you during the year and the deductions that were withheld from that income. Attach only the other supporting documents that are requested in the guide to support a credit or deduction.
If you make a claim without the requested supporting document, the CRA may disallow the credit or deduction you claimed. It could also delay the processing of your return.
Keep all supporting documents for 6 years.

Are you a non-resident? Which form did you use? Too much info on that canada.ca website with no straight answers!!!!!! Help :(
@cathyo1985 - It really all depends on your residency status, which can be determine here https://bit.ly/2NDcHze
Reporting foreign income on your Canadian tax return can get tricky, so for tax purposes your residency status is the first thing the CRA wants to know.
Non-residents and deemed non-residents - report your income from Canadian sources such as the taxable part of your scholarships, fellowships, bursaries, net research grants, income from a business without a permanent establishment in Canada, and taxable capital gains from disposing of taxable Canadian property.
Deemed residents - report your world gross income. World income is income from all sources both inside and outside Canada.
Because of the many variables, please review the links provided below for greater understanding of your tax obligations.
