What is Seaforth like to live in?

Hi, we are a family with 2 kids aged 8-10 years old and are looking to relocate from Newcastle NSW. Seaforth looks pretty darn nice from the photos on the net and reminds us of our hometown. Is it suitable for a young family? Can you swim in the beach all year round? Does the beach have waves or is it generally flat? Whats the local primary school like? Where is the closest High school? Any other info that you can think of would be greatly appreciated. Cheers, Belinda
