The .Australian Union Choir is a collaboration by trade union choir members from around Australia. Brisbane started it all by organising a trip to Cuba in 2009 to take part in an international festival of choirs in Santiago de Cuba. The Sydney Trade Union Choir organised another such trip in 2013. There is another trip being organised in August 2018, this time to Timor-Leste.
