“Who is eligible to sponsor a relative?
To sponsor an applicant for a GSM visa you must be:
• an Australian citizen, permanent resident or eligible New
Zealand citizen;
• aged 18 years or over; and
• usually resident in Australia”
如果你亲属，即时几年内住够好几年， 满足 usually resident. 但现在已经不住在澳洲，也很难证明他们有意愿继续呆在澳洲。亲属担保的本来目的就是，让亲属照顾新移民。。如果在澳亲属不住在澳洲，新移民还有谁去靠？
After living for two (2) years and working for at least one (1) year in a Specified Regional Area, applicants can apply for a permanent visa.
比 485 好转PR 因为 485 纯粹就是一个类似于working visa 的临时签证，PR 申请与 485 可以没有任何直接因果关系。485 之后，你还必须 在 18年凑够 “相关” 工作经验 或考高分雅思 才能满足将来更难pass 的 PR 申请条件。
