Australia Luxury Trip Review, Mornington Peninsula, Wildlife Reserve, River Float near Mossman Gorge, Biking Sydney

We enjoyed all of our excursions but a few that the agency arranged really stood out:
The travel to the wildlife reserves with Echidna was great -- we saw animals in two different wildlife reserves with a small group and gained a good understanding of how amazing and how endangered these animals are.
We loved our day on the Mornington peninsula near Melbourne with our guide of a local tour company.  She took us to beautiful sites and customized the day for us based on our interests.  
The snorkel and Dive trip to the Great Barrier reef was also terrific; it was great to be on a ship that offered both diving and snorkeling so that we could all be together.
We did another interesting trip in the rainforest near the Great Barrier Reef.  We did a river raft "float" down one of the rivers near the Mossman Gorge.  It was a fun, unusual, relaxing way to see a part of the rainforest.
The biking excursion in Sydney was also a highlight -- it was the perfect way to see the city at our own pace yet cover many of the highlights in a reasonable time.
We did really like the Sydney Harbor bridge climb -- even though I was a little bit apprehensive to start!
