Hi Anthea, secret harbour is a pretty place and close to the beach, so far I have found the schools to be great. House prices are good and you get a lot of house for your money the downside is that you are quite a way out. There is a small shopping centre with most of what you need, GP , dentist , pub, woolworths, post office, hairdresser, cafe etc. work opportunity is limited though and when living in secret harbour I think most people have to travel.
Secert harbour does offer a sense of community and its clean.
Pit all depends on what you want for you and your family really, everyone has different needs. I would agree with Zoe , if you can get a short rental that would give you opportunity to have a look round.
it is difficult to choose an area when choosing from so far away.
