Just a tip for those wanting to visit Taronga -
The next two weeks are the best time to visit the zoo (during the week is better than the weekend).
The holidays are over, the schools have gone back, but they have not had time to organise school excursions to the zoo. You will only have to contend with predominantly overseas tourists, families with small children too young for school, and university students who don't go back to uni for another month.
Usually, February has good weather too but I won't make any predictions about that!
