<blockquote class="Quote" rel="rolly04">@shirlie technically mali ang ginawa ng accountant mo. Your accountant should not advise you to file your tax return and claim medicare levy exemption without the letter. Pero sa dami ng taxpayers ng australia, i dont think ATO can find out na wala kang letter bago ka nagfile. </blockquote>
