Tammin Observing Site

ASWA manages a dark sky observing site in the Western Australian wheatbelt town of Tammin, about two hours’ drive east of Perth. This site is set up for use by ASWA members and invited guests. The site largely consists of an open field for setting up observing and camping equipment. On-site facilities include a shed, sea container with shade gazebo, toilets and mains water. The club is currently in the process of creating individual, level viewing pads next to which members can park and camp.

The site boasts stunning horizons, good darkness, excellent proximity to facilities in Tammin and ease of access from Perth (easy two hour drive out the Great Eastern Highway).

ASWA members may use the site provided they have had a site induction. Guests must be accompanied on-site at all times by an ASWA member who is responsible for their actions. In order to access the site, lock-codes are required for the entry gate, toilets and shed. Use of the site is free for ASWA members and guests.

In the future we hope to have facilities suitable for tourists and international guests to use at this wonderful dark sky location.



On-site accommodation is currently limited to BYO tent/caravan camping. We hope to eventually have substantial accommodation on-site.

The Tammin Hotel/Motel has comfortable air-conditioned rooms available.

Tammin Guest House - Consists of 20 bedrooms, shared bathrooms, a common room and full commercial kitchen facilities. Rooms include two beds. Rate as at Dec 09 $38.50/room/night (enquire to confirm price at time of booking). Phone 9635 1500 for enquires and booking.

Getting there
The site is on Lowles Rd about 7km north of the Tammin.Access is via locked gates off Lowles Rd, about 200m from the Tammin-Wyalkatchem Rd. Getting there is easy by car travelling east from Mundaring on the Great Eastern Highway until you reach Tammin. The first left in Tammin is the Tammin-Wyalkatchem Rd, follow this until Lowles Rd.

Passenger trains stop at Tammin several times per week, and buses travel through Tammin on a regular basis. These are alternative ways to get there if you do not have your own car. You would need to organise transport from the town of Tammin to the ASWA site (roughly 7km).

Can you help?
ASWA is a volunteer organisation and as such has limited resources to dedicate to improving the Tammin Observing Site.

  • If you are an ASWA Member: Use the Site! The more ASWA members we have using the site the better.
  • Spread the word about the site. The more people who know about the site the more that may use it and the more that may help us develop it.
  • Listen out for busy bee notices on the ASWA newsgroup. Examples of activities include whipper-snippering and slashing grass several times a year, refilling water storage on-site, spraying for weeds, manual weeding and other odd-jobs as they come up.
  • Offer suggestions, input and constructive criticism on the use of the site to the ASWA Council.
  • Offer hands-on help, offer to do something for the site.
