Thai GF returning home

[GoTheHighlanders]

Hey all, my Thai girlfriend got a second tourist visa for Australia, this one being a 3month multiple entry, unfortuantly just over 1 month into her stay she has had to return home due to her Grandfather been givin 10 days to live. Depending on her situation we will try to get her over within this visa if

Any way what would be the best bet for our next visa? we have been together one and a half years, would she likely get a 3rd tourist visa or is there a better path to go down so she can come and stay again? She does have a 7year old son, which would be cool if he could come over to so she dosn't feel so guilty about leaving him home with other family members.

Any help/advice is much appreciated
