Sydney Observatory and the night tour, a fantastic introduction to astronomy 

Built in 1858 and perfectly positioned on top of Observatory Hill overlooking the harbour, Sydney Observatory is the oldest observatory in Australia. Its iconic sandstone building is one of the most significant listed heritage sites in New South Wales.

Today the Observatory is also a museum as well as a public observatory. It contains an 1874 29cm lens telescope, a 42cm computer-controlled telescope and a hydrogen-alpha solar telescope. It is also home to a 3D Space Theatre and the Sydney Planetarium.

In the 19th and early 20th centuries, the Observatory played an essential role in meteorology, navigation and timekeeping, besides studying the Southern Hemisphere stars.

Sydney didn’t have an accurate time standard before the Observatory was built. Once it was operational, every day at 1pm, a “time ball” on top of the tower dropped to signal the correct time, accompanied by a cannon blast. The time ball is still dropped each day at 1pm but it uses an electric motor.

Sydney Observatory also showcases a great collection of photos, instruments and artefacts that encourage the visitor to discover the science behind weather forecasting and the history of astronomy in Australia.

Please note:

Due to Covid-19, day and night tours, name a star sessions, birthday parties and school holidays daily programs have been suspended in accordance with NSW Health guidelines. However, the Observatory building and gardens are open.

My husband and I wanted to celebrate our middle daughter’s birthday and to make her feel special. After thinking for a long time, we made up our minds and booked a night tour in the Sydney Observatory.

We arrived 20 minutes before the tour, so it allowed us time to watch the displays about the solar system and the stars of the southern sky. The guide was very informative, patient and kind. We each had a look through two of the telescopes where we managed to see several constellations and planets. We were very lucky as we had clear skies. It was amazing!

The viewing of the Planetarium and the 3D Theatre was also very interesting, although the experience with the telescopes was our favourite, maybe because of the unique sound of the dome rotating. 

Although the tour is a bit long for school-aged kids, my daughter enjoyed every single moment.

Sydney Observatory Details

Toilets / Baby change / Accessible toilet: Yes

Cafe: No. A cold drinks machine with water and soft drinks is located outside the Observatory in the rear courtyard. There is also a water bubbler in the grounds of the Observatory.

The National Trust café at the S.H. Ervin Gallery also on Observatory Hill is the closest café.

Pram/wheelchair friendly: Gardens, ground floor exhibitions and the East Dome telescope. The North and South telescopes are not accessible because of the narrow and steep staircases in the heritage-listed buildings. By prior arrangement, the Observatory can install an outdoor telescope.

Public Transport:

Sydney Observatory is well served by public transport although it is not on its doorstep.

Circular Quay Train Station, Light Rail Stop and Ferry Wharfs are a short walk away.

Bus route nearby: 311 – Millers Point to Central Railway Square via Darlinghurst & Potts Point.

Note: please, always check the latest updates before catching public transport.

Parking: Visitors can either park in Watson Road or Argyle Street both of which are metered. The Observatory is then only a short walk up Watson Road and through the Observatory Hill Park.

Mum’s report: If you are looking for a special activity that won’t break the bank, Sydney Observatory night tour is a great activity to do with children between the ages 7 and 17. Before choosing it, consider if your child has an interest in science to make the experience more enjoyable. A night date to look at the stars with your child is something that he/she will always remember, especially, if you plan to have dinner together before the tour. Also, to make the date with your child’s even more memorable, you might like to play a meaningful song on the way back home. I like Yellow by Coldplay but there are lots of other great choices!

The Sydney Observatory night tour worked very well for our family. Our middle child felt really special on that day. It was the perfect place to tell our daughter that we love her to the moon and back.
