I have been asked this question recently – and its quite valid!

Just like all of Australia, the Financial year ends on June 30th. This is different to New Zealand where it is March.

You then have until September to submit your tax return – or there is a fine which ranges in price depending on your income.

Your tax return can be done online (etax) or take all your receipts, pay summaries and information to a Tax Agent (they pop up all over the Malls around June-July for a couple of months) or Accountant. Whatever the fee is that you are charged can be taken from your tax return amount, and then claimed on the following return the next financial year, so its a win-win!
