It's an area full of lakes, of course. You can view the spectacular scene how the lakes merge into the almighty ocean, my eyes were welling when I saw this sensational meet-up.
There is a ferry touring you around the whole lakes, I bet you can see probably the most luxurious yachts and private ships over there in Australia.
There is an island named Raymond island, maybe it one of places inhabited by the koalas. If you drive into the jungles, there might be groups kangaroos greeting and entertaining you in the wild.
In the evening or early morning, there will be fresh seafood selling. That will attract any seafood lovers to frequent the returned the boats and try their luck in the fisherman's harvest!
There is a place named "Silt Jetty" naturally formed by sea waves, extending to the heart of the lakes. It has been claimed the longest natural jetty in the world after the one in New Orleans (USA) was destroyed in the disastrous flood.
It's hard to find though, that's why it hasn't been well-known yet. You will need a GPS to guide you there.
Anyway, the staff in the information center will tell you all of these.
One more tip: It will be nice for you to book the holiday flat outside the town, it's much cheaper and less crowded. Besides, the town is not huge one, so it will be easy for you to get around.
