Hi Sarah,
I have just come back from Hamilton Island in the Whitsundays and I
think this would be a great place for you and your family to go to.
There's the beach as well many of the hotels have their own pools, so
you can just relax and watch the kids at the same time. There are lots
of different bush walks you can do and I'm sure there will be lots of
native birds and wildlife that you will be able to point out along the
way to your children. Of course you can go snorkelling and use the
catamarans - great fun for the whole family. There are also spa
facitilities, mini golf, a driving range, tennis & squash courts and of
course its lots of fun driving around in the golf buggies too. I'm sure
you're family would love it there as its very family friendly! Enjoy!!!
