We couldn't, at first (the Australian pronunciation removes the "ir" so it sounds like "Cans").
We arrived Monday after a short flight from Sydney and were surprised to gain an hour - the town is virtually due north of Sydney (but the difference is due to daylight savings time, or so we were told!). First stop was the Budget rental car desk where we met Ian, perhaps the most friendly and helpful Australian ever. He gave us various maps and recommendations and also noted he had visited 41 out of all 50 US states - more than either of us! We got settled into our rental car, which will be taking us down the coast back to Sydney over the next three weeks, and Alex tried to adjust to sitting in the right seat and driving on the left side of the road. He seemed nervous at first but definitely has the hang of it now!
The Cairns airport is only ten minutes from town so we were able to check in to our hostel quickly. Neither of us got much sleep during the previous night so after booking a reef tour (thanks Ian!) we headed straight to the water.
During "stinger season" you can't swim in certain areas of the water along Australia's coast because of the jellyfish migration. However, the beachside towns have compensated by either putting up large nets or creating an alternative swimming space. In Cairns there is a huge public swimming pool and park called The Lagoon, located right off the beach. We found a great spot under a palm tree and perched there for most of the afternoon, reading and taking multiple dips in the pool to cool down.
Cairns is a pretty laid-back beach town, at least during this time of year. We suspect that it gets more crowded once the holidays near but there wasn't much action at most of the shops, bars and restaurants. We picked a cute little Greek spot for dinner, Fetta's, and left only after we'd seen our fair share of plates get broken (but before the owner - who seemed quite drunk at this point - started pulling people out of their chair to start dancing).
Tomorrow we get up early to explore the Great Barrier Reef so we are pretty excited!
