I was in St. Peterburg in 1990. It's hard to remember specific things to do there after 16 years but I can tell you it's a beautiful city, much nicer than Moscow.
There's the obvious sights in China, the Forbidden Palace, Tianamen Square, the Great Wall etc. I'd also go and see the The Emperor's Summer Palace and the Chinese acrobats.
The only part of Australia I've been to is Sydney. There's lots to see and do there but you should definitely go and see the Blue Mountains which are about 100k outside of the city. Also, spend some time around the Harbour area. It's a beautiful area of Sydney and there's plenty to do there. You could visit the aquarium or go whale watching on a catamaran, stuff like that. I'd particularly recommend the latter. There's plenty of nightlife as well. All in all it's a great city.
If you have time in New Zealand I'd strongly recommend that you take a drive from Picton, which is the northern ferry town of the southern island, down the west coast as far as Queenstown. It's possible to do it in one day if you're prepared to spend about 14-15 hours driving in one sitting but if you want to appreciate your surroundings you're better off spreading the drive out over 2-3 days. The drive is pretty much all through national parks and mountain ranges. Spend a few days in Queenstown and do as many of the outdoor activities as you can. I also recommend doing a helicopter ride on to one of the glaciers. Queenstown is expensive but there's loads to do and it's a place that you'll never forget. Just another pointer, I wouldn't spend a long time in any of the major NZ cities, Auckland, Wellington, Christchurch as 3-4 days in each of these is more than enought to see what they have to offer.
That's all I can say I'm afraid as I haven't been to any of the other places.
Anyway, enjoy.
