Sydney Observatory

You are here Home  > New South Wales  > Sydney >  Sydney Observatory

Sydney Observatory is Australia’s oldest observatory. It features an exhibition on astronomy and its context in Australian history.

A daytime visit gives you access to the gardens and the exhibits inside the complex, but does not give you access to the telescope domes, telescope viewing or the planetarium.

Nighttime sessions run for around 90 minutes give you access to telescope viewing. If telescope viewing is not feasible due to sky conditions then a planetarium session will be provided instead.

Free entry with the iVenture Sydney card

    closed for a private wedding party when we visited...but here’s a hidden gem as a place we can enjoy a panoramic view of the city from the hill!

    Very interesting but displays are very static. More hands on would be nice. Free entry.

    Great place to visit in the day, interesting exhibition and it's free. Did you know James Cook came to Australia to view the transit of Venus in 1769?

    Go to the Sydney Observatory and do one of their Night Telescope Viewings. On a clear night you'll get to use both their telescopes – including one from 1874. Really an amazing night!
