Canon 350D and the 18-55mm lens. I did get quite a bit of dirt on the viewfinder during the trip so I took it to a very good camera shop in Sydney opposite Hyde Park and it cost $65 dollars to get it cleaned. It only took an hour and it was like new when I got it back.
Funny you should mention fireworks. On our last evening in Sydney we had dinner out on the terrace of Cafe Sydney overlooking the harbour. There was a new ship in the harbour, Pacific Dawn, you might have seen it on the news. So not only did we get a great view that night we also got the added bonus of fireworks over the harbour!
