Want to play two-up outside of Anzac Day? Head to Broken Hill

Unless you're in Broken Hill or Kalgoorlie.

Two-up is most commonly played on Anzac Day and involves betting on two coins being flipped.

It was popularised by Australian soldiers who played the game during World War I.

By law, specifically The Gambling (Two-up) Act 1998, the game can only be played on Anzac Day, Remembrance Day (after 12pm) or Victory in the Pacific Day (August 15).

The only exception in New South Wales is mining town Broken Hill where locals lobbied the government to grant them a special license to play the game all year.

The council's lobbying efforts saw two-up recognised in 1992 by the NSW Office of Liquor, Gaming and Racing as "an established part of the cultural heritage of this mining city".

That cultural heritage was an illegal two-up school which operated in a laneway of Argent Street throughout the 20th century.

However, when the set up was shut down by police in 1984, the local council and community came together to make their beloved game legal.

The Palace Hotel on Argent Street is the single approved location in Broken Hill granted license by the Broken Hill City Council.

Games are regularly played on Friday nights and at special request.

The pub is well known for its colourful interiors and was featured in the 1995 film The Adventures of Priscilla, Queen of the Desert.

Western Australian mining town Kalgoorlie is the only other location granted exception in the country.

Ten minutes out of town, an original two-up school made from corrugated iron still stands and operates on weekends and public holidays
