Something similar can be expected via email according to SCAMwatch:
"Added: August 2013
SCAMwatch and the Australian Taxation Office (ATO) are urging consumers and small businesses to be aware of tax refund email scams, with scammers taking advantage of the busy nature of tax time to target you.
A new phishing email claiming to be from the ATO is currently circulating that claims you are entitled to a tax refund. All you have to do is click on an embedded link and complete an online form. But watch out – the online form and link are fake, and are designed to steal your personal information or infect your computer with malware."
