Hi Sarah,
Good luck with the move.
There is also a caravan park
Barwon Caravan & Tourist Park down the road from the Big4-opposite the park and river. I don't have any personal experience of it though.
Montpellier is a great school, I have been happy with it - there are quite a few families from the Uk there.There is also Highton Primary School which has an equally good reputation.
Highton is a good little shopping centre-supermarket,bakery,chemists real estate agents, coffee shops etc.Also a library.There are also shops, a big Kmart etc in the other direction in Belmont.
The libraries allow free internet access for an hour if you take id, found that invaluable when we first arrived( now work for the library!).
There is loads for the kids to do- the Geelong Aquatic Centre is near to Highton where they do swimming classes for all ages.Also my kids got involved in cubs/guides which are also local.If that is not their thing, there are lots of other options such as sport.
A bit off the topic but the governement has just announced a $25,000 package for each doctor's practice to employ a practice nurse-hopefully should be jobs created!
All the best
Liz
