Download coordinates as: Wallangarra is a rural town and locality in the Southern Downs Region, Queensland, Australia on the border with New South Wales.

[2][3] It is the third-most southerly town in Queensland, 258 kilometres (160 mi) south west of Brisbane.

[5] The town would provide a break-of-gauge between Queensland's narrow gauge Southern railway line of 3 ft 6 in (1,067 mm) and New South Wales's standard gauge Main North railway line of 4 ft 8+1⁄2 in (1,435 mm) when the two systems came together in 1888.

A medical screening process was used to determine if Queensland residents could safely return to the state.

[15] The plant was located on the border so as to take advantage of rail lines from both Queensland and NSW.

[citation needed] Access to the army stores was via Margetts St, one of the main roads in the town.

The late Muriel Daphne Verdun Nicolson lived at 30 Margetts St from before WWII until her death in 2001.

[16] On 12 September 1964, St Gabrielle's Anglican Church was dedicated by Bishop John Hudson.

[18][19][20][21] Taking advantage of the rail junction Riverina Stock Feeds operated a packing plant opposite the Wallangarra railway station for many years until 1995.

The abattoir shut down in July 2016 for "the short to medium term" blaming low stock numbers and poor global trading conditions.

This gap has made Wallangarra the major inland border crossing for the New England Highway and what was the first railway line between Brisbane and Sydney.

Wallangarra is the coldest town by mean maximum temperature in Queensland, due to its altitude and extreme southern location in the state.

[24] However due to its exposed location, minimum temperatures are not particularly low; towns of significantly lower altitude such as Warwick and Oakey frequently record lower minima, and especially Stanthorpe of similar altitude but much flatter topography − which in turn causes warmer daytime temperatures and less snowfall compared to Wallangarra.

[16] The Wallangarra branch of the Queensland Country Women's Association has its rooms at 52 Rockwell Street.
