They have an old Bondi tram, overseas trams, and tramrides, including rides to the Royal National Park. They also have a large display area.

Very much a community art gallery, surrounded by pretty gardens. Nice coffee shop in amongst it all.
A large collection of native plants, paved walks, barbecues well stocked with wood, and water views. This place is unknown to most, and is never crowded, except when hosting and occasional wedding. Lots of Australian plant species, and well worth grabbing some sausages, some matches, and heading over for a barbecue.
One of the finest examples of Australian remnant bushland about 30 minutes drive of the CBD. Features bushwalking, swimming, bike trails as well as play equipment for children. The lookouts over the Georges River are also well worth a look. There is plenty of parking in the park.
Almost as nice as the nearby Royal National Park, with just a fraction of the visitors. Contains short walking tracks to several wild swimming holes, with easy access from the Heathcote and Waterfall train stations.
You can stand on the rock where Captain Cook first stepped ashore, starting the process of European settlement. The landing place is also now next to a large oil refinery. There is a monument walk here, and an interpretive visitors centre. The area is never crowded with visitors, and many Sydneysiders have never visited. There are usually plenty of available and well maintained electric barbecues and picnic tables by the water. Buses can be a couple of hours apart so check the times. Sutherland Shire used to be named the birthplace of modern Australia, referring to European settlement. Now the aspects of the Aboriginal and European settlement interaction are emphasised, and interpreted in the visitors centre in the park.
The Towra point wetland is an imporant resource for migratory birds, with mangroves and inter-tidal mud-flats. It is a protected area, and mostly not open to visitors. The National Park Visitors Centre at Kurnell does organise tours occasionally. There are three points available to view over the wetland, each off Captain Cook Drive, and worth stopping at if you are on the way to Kurnell. Between November and March you may spot the migratory Eastern Curlew, which spends the other half of the year in Siberia. Take your binoculars.
