First off, we though the $40 general entry gate ticket was a bit steep (slightly cheaper if booked online) but appreciate proceeds go towards the running of the Park. The even more expensive options include a variety of high wire/rope activities.
Bigger than expected, with the main area accessed via a foot tunnel under the coastal highway and you can also hop-on hop-off one of the 2 miniature trains running a circular route throughout the day. Lots of rangers who are happy to chat about the birds or animals under their particular supervision and various feeding activities and other demonstrations at scheduled times. We enjoyed seeing the dingoes being fed.
A very large aviary is part of the interesting 'Lost Valley area. There is also a very good nursery for the breeding koalas and for the overseas visitors there is the obligatory staged photo opportunity.
For pit stops there are a couple of cafes - we had a couple of average coffees at the General Store - and there are two gift shops if you feel inclined for a souvenir.
