妈妈父母付费移民（2012），爸爸等待五年团聚问题

JENNYZHANG

请教大家一下：妈妈2012。4获得父母付费移民签证，2012。8入境。现在纠结在老爸打算办等五年配偶团聚移民subclass 309。
请问大家：1。五年时间是从2012。4算还是2012。8？
2。我查了一下Partner Migration booklet, P14:Sponsorship eligibility
The following information is intended for you as the Australian citizen, Australian permanent resident or
eligible New Zealand citizen who wishes to sponsor the visa applicant as your fiancé(e) or partner to
Australia.
If you wish to sponsor the visa applicant as your fiancé(e) or partner, you must:
• be an Australian citizen, Australian permanent resident or eligible New Zealand citizen; but
• not be the holder of a Woman at Risk visa (subclass 204) that has been granted in the past 5 years
and now wishes to sponsor their partner or former partner that they had at the time of visa grant.
If you are an Australian permanent resident or eligible New Zealand citizen, you are required to be usually
resident in Australia.,什么是usually resident？妈妈可以在这五年离开澳大利亚吗？可以多久？
非常感谢。

从你妈妈入境开始算起。

你妈妈这五年累积在澳洲住满两年就可以滴。
