Coordinates: 31°56′58″S 115°51′46″E / 31.94934°S 115.86289°E The Perth Trades Hall is the Trades Hall building in Perth occupied by various organisations of the Western Australian trade union movement. The present Perth Trades Hall, at Unity House, 77-79 Stirling Street, was opened on May Day, 2000. It provides offices and meeting rooms for trade unions, the Australian Labor Party and other community and political groups. The Trades and Labour Council (TLC), now known as UnionsWA, relocated in 2007 to the CSA Building at 445 Hay Street, Perth.
Although a Trades and Labour Council (TLC) was established in Perth in 1891, finances to build a trades hall were not available until 1911, when Alick McCallum became general secretary of the Australian Labour Federation, as the TLC was then called.
Design and construction of the original trades hall building was largely due to the efforts of Ernest Henshaw. The three-storey neo-Georgian building was erected at 74 Beaufort Street, the site of Perth’s original Scotch College.
