1921 WA/NT Border Determinations

During June and July 2011 it was 90 Years ago in 1921, that the SA & WA Government Astronomers, Dodwell & Curlewis respectively, travelled to the Kimberley by ship to Wyndham, then on to Argyle Station, hosted by MP Durack, who guided them to a point supposedly close to the border of Argyle Downs Station with the north western boundary of that part of Rosewood Station which lies in the Northern Territory. That boundary was supposed to be on 129 degrees east meridian, which is also the WA/NT border.
  They set up about 2 ½ km south-east of the confluence of Hicks & Bobtail Creeks, close to the north bank of Bobtail, at a site that was later named as the Austral Pillar, where they carried out tests utilising the latest technology of the day, being radio transmissions of the time signal pips, that you should recall hearing before the news on the radio.

  They measured these time signals from all over the world, to determine how far east of Greenwich they were, hence the position of the WA/NT border on the ground.

  As it turned out MP Durack would not have been impressed, because he lost just over a 2km wide slice of what he had believed to be Argyle station land to Jack Kilfoyle of Rosewood, as the border was about 2km west of their position.

Research on South Australia and the WA/NT border

  Research with the department responsible for lands in South Australia has found new information on the 1921 determinations and a new set of 1921 photographs from the family of former SA Surveyor-General Clive Melville Hambidge, who was a surveyor on the 1921 border determinations. These archival documents and prints were kindly sent to KHS via Chris Jordan, who liaised with former SA Surveyor General, John Porter to supply the Hambidge Family Collection to KHS. The photographs have now been digitised and are available from below.

  Just over 2km from the Austral Pillar (1921) site is the Kimberley Obelisk, constructed in 1927 by the WA Lands and Surveys Department, near the confluence of Hicks and Bobtail creeks, to officially mark the WA/NT border (129 degrees east), on the ground.

  A line run north to the coast and south to the 26th parallel, through a cross marked in a copper plug, embedded into the top centre of the Kimberley Obelisk, officially marks the WA/NT border on the ground, although due to early inaccuracies, the 129th Meridian is actually some distance west of the Obelisk.

 Another line is run through a similar marker, the Deakin Obelisk, near the Trans-Continental railway, and at the Deakin Obelisk a line is run north to the 26th parallel (26 degrees South - the border of South Australia and the Northern Territory), but where they meet the 26th parallel...

Due to slight inaccuracies in those early days of 1921 and 1927, at the 26th parallel is a section of the NT/WA border that runs sideways east-west for 126.943 metres and is marked at and known as "Surveyor General's Corner."

Another interesting fact is, that due to these early inaccuracies, both of the border marker Obelisks are actually east of the 129th Meridian by some degree, so that officially both borders encroach over the edge of this Meridian, allowing WA a small slice (each just over a kilometre wide), of both South Australia and the Territory.

Recent archive images of the freshly completed Kimberley Obelisk in June 1927, when WA Governor, Sir William Campion visited the site, have recently been digitised from Elizabeth Durack's personal photographic collection (61 photographic prints) courtesy of the Durack family.

The Durack & Hambidge collections, help to show the local, State and National "significance" of these border determinations.

The KHS Archive and Museum has a permanent display about the border markers with new information that has recently been researched on the June and July 1921 Austral Pillar border determinations. If in Kununurra visit the museum to find out more about the border.
