My family and I purchased land and built in Newport and have been there around 18 months. The older area is largely retirees but the new area is a mixture of professional type families with with young or school aged children. The area is great overall with plenty of good schools. Our children are due to attend school in the next couple of years and we have chosen Mueller College due to it excellent reputation and great facilities. There are plenty of other good options as well which are all nearby including Grace, Southern Cross College and a myriad of public schools. The area is good to live in with plenty to do for kids. I believe it is a bit of a hidden gem at the moment with house prices still relatively affordable for beach type suburbs. I think it the next few years it will increase significantly in price (hence why we bought in the area). One issue that does annoy me is I work on the south side of Brisbane and traffic isn't horrible but can be annoying once you get off the peninsula.
Overall good place to live with loads of potential.
