It is interesting as mine were 13, 11 and 5 when we moved here. It was the 5 year old who struggled the most and would have moved back even after 2 years! It took 3 for him to really meet a lovely set of friends who I suspect he will know and like for the rest of his school years. I do find in some schools Australian children aren't as used to different accents of children who have travelled a bit. It's not malicious but they don't make the effort. That's why I've often provided a helping hand... I figure it's the only time I might have a choice to influence so I do my classroom research. Volunteering at school every once in a while (and yes I do work full time so know it's hard) gives me good insight into whether they REALLY have no friends, are using the friendship card for manipulation and provides some insight into who I would LIKE them to be friends with. Good luck. I always say - it's easy to make the move for yourself but when one or more of the wee ones aren't happy it's heart wrenching. That's until I realised that 13 particularly is a very difficult year (and some would say 9 year old girls are the worst!) so it could just as well have happened back home.
