Hi Caroline
Joondalup is nice, there are lots of good suburbs around there. Probably the nicest are Iluka and mindarie, a bit more expensive though. Further up the coast is Quinns Rock, we used to live there and walked to the beach from our house everyday. Currambine and Kinross are good suburbs too. If you go into
www.realestate.com.au you'll be able to search for houses in and around Joondalup. There is an excellent train service that goes from Clarkston to the city so most of the beach suburbs would be accessible. Further south of Joondalup there is Whitfords, Hillarys, Trigg, Kallaroo, Mullalo all good suburbs close enough to commute to Joondalup from. Hillarys has a fantastic kiddies beach, no surf....Would probably stay clear of Balga, West Minster, Nollamara, (sorry to anyone who lives there) The beach suburbs are more expensive than the suburbs a bit further in. On saying that most of the inward sprawl is still within 30 minutes drive of the beaches. Which by the way are wonderful. My advise is to take a short rental (3-6 months) to begin with and then drive around and find the place that fits you and your family. Good luck.
