We made use of the trains to get us to the YHA in the city centre. It's a ridiculously-priced hostel, and it's very big and uninteresting, like most of the YHAs we've stayed in, but there are no prostitutes outside and no strip clubs underneath, so maybe that's a good thing. We left our bags in the room and then went for another walk through the town to see some things.

We stopped at Qantas first to rearrange our Australia flights and while we were at it, we made changes to the rest of our itinerary. When we originally booked the tickets we could only make reservations 11 months in advance, so the last half-dozen flights have been squeezed into October. It's all sorted now. The Qantas lady was very helpful but was full of dire warnings about Indonesia and scare stories about terrorists. We are thinking of avoiding both Bali and Jakarta, but we have six weeks to come up with an alternative. She did, however, tell us the location of the local Krispy Kreme doughnut shop, so we went straight out for lunch.

Next stop was the Sydney aquarium, as a preliminary Finding Nemo location tour. The real thing will happen in a few weeks' time, when we go to the great barrier reef, but this was fun for now. And they also have platypuses (?) and blue penguins, so we were happy. It was still school holidays and most of the children seemed to be very unhappy at being in the place, so there was a lot of screaming going on. It was quite noisy.

The aquarium is huge and took hours to wander round. When we were finished neither of us wanted to walk that much further, so we took a bus out of town to a cinema, had supper in a nice, vegan-ish cafe and then watched a funny and slightly horrible documentary called 'Supersize Me' about a guy who eats nothing but food from McDonalds for a month. There were two things before the film, one a notice from the CEO of McDonalds telling us that the film we were about to see was rubbish, and a weird and funny short about a guy who needed to buy a tool for getting fish hooks out of fishes' mouths.
