07年7月1日後拿到PR要入籍，居澳時間最準確的說法：

If you became a permanent resident on or after 1 July 2007 you must:

have been living in Australia on a valid Australian visa for four years immediately before applying, including one year as a permanent resident, and
not have been absent from Australia for more than one year, including no more than 90 days in the year before applying.



visa包括任何合法留澳簽證包括旅遊
申請入籍前離第一次抵達澳洲超過四年。
四年內在澳洲時間超過三年
申請入籍前持PR超過一年(不限居留澳洲時間)
申請入籍前一年離澳時間 <90天
