Right (she said, rolling up her sleeves, ready for a fight!)
IMHO every school is different and just because Mrs T's local public schools are feral, please don't think that's the norm. Grr!
There are a lot of private schools in SA (don't know about the rest of Oz), but what might seem cheap when translated into pounds, isn't when you are living on Australian wages, so the majority of children attend public schools.
It was super hard trying to suss a prospective school out. Our kids were just 10 and 13 when we arrived. The 13yr-old had been attending grammar school in Tonbridge, but both started in primary school as children are at primary school until yr 7 (13/14). The elder then went to one of the three schools that offer the IGNITE programme- it offers enhanced learning programmes for the gifted and talented (goodness knows how she swung that!)-, and is a public school. She much prefers it to the grammar and feels much more challenged (and not just by having me as a parent!).A friends daughter went to a private girl's school - a 'good' one- where she had such problems with bullies, she left and now happily attends a public school. The younger has a fab time and although he says there is still bullying, the principal is great at sorting it out, and it doesn't seem to re-occur. In his experience. And it's apparently easy as to change schools if the child isn't happy.
I HATE bullies.

Our younger encountered problems with a few of the high school kids. I went to the school, they immediately listened, spoke to the lads involved, and kept us informed every step of the way. I bet both your girls will have a fab time here, with the beaches, the koalas (loads of them, in the trees, the gardens etc), budgies in the trees, friendly child-orientated living, and so many cool hobbies to be had !
