Wow, congratulations on getting your RRV!
Just goes to that being granted an RRV is unpredictable (hubs has been granted 1 year RRV subclass 155, though he had been living in Australia for 1 year in the past 5, has a job offer, and our kids and I are all Australian).
Best of luck with visas for your partner and daughter - you shouldn't have any problems, but the members here are a wealth of information ☺
Welcome, and good luck!
