AT THE POINT (Substitute point)
Observations carried out 205kms from the Substitute point. The actual degree point is 45kms S of the Qld-NSW border (inability to secure permission to enter property). Site is adjacent to the Macintyre River, part of the Darling River system. As the true point 29 °S 150°E is well into NSW, a substitute point on the Macintyre River was established.

IN THE DEGREE SQUARE
Climate: The closest weather station is at the Moree Aerodrome in NSW (053115), which is 53km north-north-east of the confluence, and has an elevation of 213m.
The highest temperature recorded was 43.0°C in January 2003, and the lowest was -4.3°C in June 1971. The most rainfall recorded in a year was 848.6 mm in 2004, and the least was 277.4 mm in 2002. These and other climate statistics for Moree can be found at: Australian Bureau of Meteorology, http://www.bom.gov.au/climate/averages/tables/cw_053115_All.shtml
Extremes of Nature: Since 1906 there have been no cyclones to pass within 50 km of the degree confluence, but 7 have passed within 200 km. Cyclone information for this area and all of Australia can be found at the Australian Bureau of Meteorology website, http://www.bom.gov.au/cgi-bin/silo/cyclones.cgi

The area can experience some heat throughout much of the year, with Moree having an average of 128 days annually with maximum temperatures equal to or over 30°C, 35 days of which reach 35°C or more. In contrast, Moree can also experience chilly conditions, experiencing on average 30 days annually with minimum temperatures equal to or less than 2°C.
The population of the degree square at the 2011 national census was 5794, the bulk of them living in Goondiwindi.
The well known bridge crossing the Macintyre River at Goondiwindi is still used, but most traffic moving between Qld and NSW in this area uses the newer crossing east of the town. The Macintyre-Barwon-Darling-Murray forms the longest continuous river system in Australia at 3370km. On occasion the Macintyre, like other river systems, experiences flooding.
Goondiwindi, on the Macintyre River, is an important rural, retail and transport service centre. Cotton, wheat, sheep and cattle are produced in the district. A railway line passes east-west through the town. Five highways radiate from the town - the Cunningham, Barwon, Leichardt (Qld), Newell, and Bruxner (NSW).
