Cairns is in Northern Australia. It's known for scuba diving on the Great Barrier Reef (at least for tourists). Hubby booked us onto a dive charter that was infinitely more luxurious than any other dive operation I have ever experienced. It was a triple decker boat with multiple lounges, a large dining room and a huge area for suiting up before the dive.
The dive company had its own catering division. (Great food has never been a factor in diving, you're lucky to get a beer after you come out of the water). This one served 'morning tea' with cakes in addition to a great lunch buffet. Mom liked this part the most. In fact, I never saw her get her hair wet during the entire trip of 'snorkeling' that she was booked on.
Unfortunately, the skies were grey and rainy. Visibility wasn't good, but the scenery was amazing nonetheless.
After diving, we toured the tourist-trap restaurants and ordered a kangaroo-themed Pavlova dessert. Hubby discovered a 'joey' (baby kangaroo). It was being cared for by a little girl. Her parents had accidentally killed its mother in a car accident and they took it upon themselves to raise the little one through adulthood.
