Make sure you spend some time exploring the Botanic Gardens while in Sydney. Even if parks aren't your thing this is a great place to see some views of the Opera House, Harbour Bridge, Harbour in general or to just relax and people watch. You can also use the walking route along the harbours edge to walk to Mrs MacQuaries Chair which is a popular tourist sight.
The Gardens themselves aren't what you may expect. They are basically a park with just some nice plants in and some good views. The name makes it suggest some dedicated establishment like London's Kew Gardens but it's basically a national park with some great views. Having said that you really do need to explore them even if it's just as a place to escape the chaos that can occur in Sydney at busy times of the day.
There are some nice plants and birds in there though for anybody that wants to see them.
If that hasn't persuaded you - for any movie buffs out there this is where the closing scenes of Mission Impossible 2 were filmed (that scene near the Opera House with Tom Cruise and the girl).
If that didn't work I don't know what to suggest - just visit them and you'll see what I mean. It'll be worth it for sure.
