Site is on the Wild Dog Fence, on the western border of Qld-NSW. (Permit required to travel along the fence.)
IN THE DEGREE SQUARE
Paroo River Causeway
At Hungerford, the Paroo River consists of a number of channels that separate and rejoin as they flow southwards. As the Paroo approaches the Darling (in NSW) it spreads out across a floodplain.
The River's catchment (of 76,000 sq km) is mostly westerly in the Murray-Darling Basin. The Paroo is regarded as the last free-flowing river in the Basin.

Climate: The closest weather station is at the Wanaaring Post Office in NSW, which is 80 km south-south-east of the confluence and has an elevation of 108 m.
The highest temperature recorded was 47.0°C in January 2001, and the lowest was -3.9°C in July 1997. The greatest rainfall recorded in a year was 746.6 mm in 1976, and the lowest was 45.0 mm in 1982. These and other climate statistics for Wanaaring can be found at: Australian Bureau of Meteorology, http://www.bom.gov.au/climate/averages/tables/cw_048079_All.shtml
Extremes of Nature: Since 1906 there have been no cyclones to pass within 50 km of the degree confluence, but two have passed within 200 km (Agnes, 1956; and David, 1976). 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 extreme heat throughout some of the year, with Wanaaring having an average of 72 days annually with maximum temperatures equal to or over 35°C. The area is also quite dry, an experiences on average only 32 days a year with rain.
The population of the degree square is probably less than 20.
Currawinya National Park.
Currawinya NP, a former sheep station, is an important area due to its size (151,000 ha), diversity of landforms and species, and Ramsar listed wetlands of significance.
Mulga dominates the area, and coolibah and red river gum are found along eh Paroo, which forms the park's eastern boundary. Birdlife is prolific at the parks two main lakes.
