The Narrabri Observatory is part of the Australia Telescope National Facility (ATNF), which is operated by the CSIRO; the Site Manager is Brett Hiscock. The site contains the Australia Telescope Compact Array (ATCA), which consists of five moveable antennas on a 3-km east-west railtrack with a 200m north-south spur, and a 6th antenna 3 km further to the west. The site used to be the home of the CSIRO's solar radioheliograph. The central area of the observatory contains a control building with offices, a library, laboratories, workshops, and The Lodge for visitors and local staff.

Also on site are the Sydney University Stellar Interferometer (SUSI), IPS Space Services and the University of Birmingham solar seismology installation.

The Observatory is situated 24 km west of the town of Narrabri, which is approximately 540 km north-west of Sydney. Narrabri has a population of about 7,250 and is the centre of a large irrigation and dry-land farming district which produces cotton, oilseed, premium grade wheat, grain sorghum, and raises cattle and sheep. Some of the surrounding tourist attractions are described at the end of this guide.

The telescope is at latitude -30o18' 52".048, longitude +149o32' 56"327 (east of Greenwich) and its height above sea level is 209.3m. The environment is modestly dry. Temperatures are typically above 30oC on summer afternoons (e.g. January,February), and are close to 0oC on winter mornings (e.g. June, July).

How to get to the Narrabri Observatory

Narrabri is at the intersection of the Newell and Kamilaroi Highways making driving from eastern seaboard cities straight forward. It can also be reached by air or rail from Sydney.

Always let the Observatory personnel know your travel plans so accommodation arrangements can be made for you. Please use the ATNF Reservation Form to do this.

We generally organise a taxi to meet people at the airport or train station (however, sometimes local staff will meet you). If, for some reason, the taxi fails to appear, contact the taxi service on 6792 2552 (note the taxi service is very competent at keeping track of late planes and trains).

Visitors may also like to consider renting a car from the airport. For a two-day visit, this is mildly more economical than two taxi trips. For longer visits, taxis are more economical. See here for local car rental agencies.

Please also let the staff know if your travel plans change.


  • Going by air: There are currently no direct flights to Narrabri. The quickest way to get to Narrabri is to fly to Moree or Tamworth and hire a car. For more information please refer to the Current Issues webpage.

  • Going by rail:
    There is a daily train service between Sydney and Narrabri. The train departs Sydney 10:05am and arrives in Narrabri at 5:41pm. The return journey leaves Narrabri at 09:25am and arrives in Sydney at 05:03pm.
    See the CountryLink Web pages for current information and timetables on rail travel between Sydney and Narrabri. Reservations are required, and the train is often full.

  • Going by car:
    The 565-km drive from Sydney takes approximately 7.5 hours. You have a choice of two routes: North via the Pacific Highway through Cessnock (Hunter Valley wine country), or west over the Blue Mountains (very scenic). You can obtain an idea of these routes by consulting the Map of Central NSW (which includes Sydney) and the Map of Northern NSW (which includes Narrabri). A strip map is available showing the main centres along the way to Narrabri. However, the most difficult part is getting to Narrabri from Sydney is to get out of Sydney. For that, a detailed map is required.

  • Driving from Narrabri township to Narrabri Observatory:
    See the separate documentation on getting to the Observatory.
