Beautiful photos Bom. We did something similar when I was a kid. Went up to Cairns, Port Douglas and drove further up to places where literally the rainforest met the sea.
We also went snorkeling and it was just amazing. The noise the parrotfish (I think it was) make when they crunch on the coral though makes me shudder.
Still my most favourite place in Australia was NT. It is just another kind of stunning up there. We met some really awesome people (this guy who had walked the Olgas and was now climbing Uluru with bare feet) and the scenery was mind blowing. Makes you feel really small and insignificant haha.
Great photos. I am not much of a traveller but I wish so many more people would realise just how much Australia has to offer outside the cities and suburbs.
