楼主的情况可以这么办理可以全家拿到下一个5年RRV:
楼主在第一个5年里注满了2年,可以顺利拿到第二个5年期签证;
楼主的老婆孩子和楼主一起拿到和楼主一样有效期的RRV。
参考: http://www.immi.gov.au/migrants/residents/155/eligibility.htm网页上的table 1。第一条适用于楼主(Five year visa->You must have spent two of the last five years in Australia.),第三条适用于楼主的老婆孩子(Member of a family unit – until expiry of the present visa holder->You are the immediate family member of a Resident Return visa holder.)
