Fort Hike.  One day Eric and I checked out the old defenses for Brisbane on the island.  It was pretty cool and being the largest Koala preserve in AU we figured this was our opportunity to see some.  We sure did.  They were all sleeping though as it was pretty warm that day.  The views were beautiful from the top of the island.  At one point we heard a loud "Boom!" and were freaking out because we weren't sure what it was.  Then we remembered what our boat captain said when we were snorkeling.  No we hadn't been transported back in time on a Dharma Island, it was the AU Air Force practicing bombing runs on Rattlesnake Island nearby.

The one thing that did make us nervous was learning of one of the island residents: The Death Adder.  Lovely name for a snake, and apparently accurate.  That kept us aware of the trail as we were hiking.
