I can highly recommend the Port Noarlunga area. We have been in Oz now 2 months and loving every minute of it. We found a rental, as some others on this thread have said in Port Noarlunga South, which is a fantastic place to bring up kids, ours are 6, 4 and 2 and loving the outside lifestyle. We are literally 5 minutes walk from South Port beach and a short 3 minute ride in the car to Port Noarlunga, or Seaford and 5 minutes to the Colonnades shopping centre. Friends of ours send their children to Port Noarlunga Primary and they love it. Freida Corp is also a fantastic Kindy, unfortunately we couldn't get our daughter in as they were full so she is going to Seaford Kindy and our 6 year old goes to All Saints Primary in Seaford, which he absolutely loves.
Also if people are reading this in preparation before coming and need short term rental I cannot speak highly enough of Tamara and Homes Downunder! We stayed in Boomerang for 11 days and had a great time, all we could have asked for when making the move. So if you need a rental in this area give her website a look over.
