Luxury Australia Vacation Review: Sydney, Melbourne, Port Douglas, Heron Island, Great Barrier Reef Snorkeling & Diving

We got to explore 4 different locations (Sydney, Port Douglas, Heron Island and Melbourne) within Australia which gave us a wonderful glimpse of those regions.  Heron Island was a highlight for nature lovers.  Diving and snorkeling on reef was another highlight since there are so many unique fish and coral to see. Also very nice that we went in late Nov which was off season so not as many tourists and weather was warm - Melbourne which has cooler temperatures was actually a relief as our final destination after experiencing 90 degree whether on the rest of our trip.
