Where did you go? Looks lovely 
The general area is known as Port Stephens but the name of the place is Nelson Bay. It is 2-1/2 hours north of Sydney which makes it close enough to visit every weekend.
As a younger bloke I would go camping there quite a few times per year, my wife and I also spent an enormous amount of time there before the kids. It is a very nice place and I have considered more than once selling my Sydney home and moving there.
But.......
I would find it impossible to find suitable work in the local area and if I had to travel for 3-4 hours per day for employment this would erode the lifestyle that would motivate such a move.

This picture shows the mainland heads. To the left is Yacabah and on the right is Tomaree. Apparently the heads are supposed to resemble some part of Jamaica or something...
