This tour was actually pretty pointless. I didn't know that most of the city highlights at Sydney could be seen in one day by just walking including the Harbor Bridge, Opera House, and Darling Harbor. I recommend saving money by doing the hop-on/hop-off tour bus or walking around yourself.
Brisbane or the Gold Coast, Australia
An amazing trip. Saw TONS of fish while snorkeling at the shipwreck, tried sandboarding for the first time, and had a good lunch at a camp on the island. I definitely recommend it for anyone!
