Hello. We are all enjoying life in Collaroy thanks. The kids really like Pittwater House although I had to take the middle one out. I won't go into reasons why but the other two are very settled. With hindsight however, I would explore other options. St Lukes at Deewhy is excellent and our son is going to Cromer Public School which has a caring feel to it, Collaroy Plateau is also a nice school. The class sizes are always smaller at the private schools. You need to see a few and make up your own mind, you'll know when you visit
Ewan is 11 (year 6), Ciaran 10 and Sienna 5 (just started Kindy).
Good luck, it is very scary moving out here but worth it. I fly back to the UK for a visit end of June...
