Small point about education: I lived on Queensland's Sunshine Coast for 7 years (was in Oz 15 years all up), and had 2 DC there. Every, and I mean every private school was run by a church. Assuming it was true what others told us, which was 'don't touch the State secondaries unless you have to!!'... my options were:
2 x Christian Fundamentalist schools that taught Creationism as fact...
1 x Catholic school with all the attendant stuff
2 x Lutheran schools (biiig in an area with a rural hinterland- lots of ex-German farmers in Oz! Esp around Adelaide )- OK, but select carefully: one had 'toned down' a bit to attract 'Church of Christ' DC (and upped its fees), the other was practically German speaking! Our close neighbours, both Lutheran teachers, taught in both and told us as much.
1 x Methodist/Presbyterian school (fundraising raffles banned...) sport, Sport, SPORT!
1 x Anglican (Australian C of E) which is always the most expensive option but probably our choice though another neighbour (and good friend) was given a job there as a Y2 teacher following a single phone interview! Even she was a bit
at the laxity of selection technique!
...and I wouldn't necessarily have wanted a religious based ed for the DC! On our 'Close' there were 14 school aged DC. I think 2 families there had DC at the same school. Not exactly promoting of community spirit!
As an aside, DH (an Australian) worked for the govt's Primary Industries in a research lab doing plant research and biology. They had quite a few school groups etc visiting, thus the noticeboards had educational posters on them. One of my DH's fellow biologists put in a formal complaint demanding the poster of Darwin be removed because it promoted Evolution over Creationism..... thankfully, he didn't succeed, but... 
We are now in Hampshire, have been for 10 years and I have to say, we both feel our DC's life opportunities are better and more varied here in the UK than they would have been in Oz. They are at a local, well-performing comp. We like walking across hill and dale; real ale; cultural difference; a wider variety of friends, many who challenge us and our beliefs on a regular basis (I see this as a good thing); short distances and varied weather! Yes, even that! In QLD, with pre-schoolers, you have to keep out of the sun between 10am and 4pm every day as the sun hammers young skins. Then it's dark by 6pm at the latest! And, unless you 'live it' you actually don't realise how boring the same weather, day in, day out, can be!
Yes, we had a back-yard pool but the DCs aren't water babies and I'm still not entirely sure the hours and $$ I spend maintaining it equalled the 'pleasure' we got out of it! Seriously.
If I had to, I would return to Oz, but I wouldn't be knocking anyone down in the rush.
