Taronga Zoo is a popular venue for weddings and corporate events, due in part to the stunning views, and therefore is used quite frequently by charter boats. In certain wind conditions, the approach can be a little tricky and uncomfortable for the smaller boats. Also note that the wharf is locked up at night time, so enquire before hand to assess suitability for your cruise.
Generally there is no charge for using this wharf.
Taronga Zoo Car Park is a reasonable value day rate. Be prepared for a bit of a walk or take the Sky Train.
