Past Brothers was founded in 1929 when former members (Tom Gorman, Gerry Allman, Stan Ross amongst others) of the Brothers Old Boys decided to found a new club to compete in the Queensland Rugby League Metropolitan competition in Brisbane.

When district football was introduced in the 1930s, Brothers clearly defied the idea as, unlike their competition counterparts Valleys, Norths, Souths, Easts and Wests, they were not a location in Brisbane.

By the time the Brisbane Broncos entered the Sydney Rugby League premiership in 1988, they were in financial trouble that only got worse as the years progressed.

Seemingly out of its financial hardship by the turn of the century, Brothers applied for a position in the 2000 and 2001 Queensland Cups, but was ultimately unsuccessful.

A new name and jersey were planned for the following year, but on 22 November the Queensland Rugby League announced, "The only club not participating in 2005 will be Brothers Diehards.

While the QRL acknowledges the rich history associated with the organisation, the club’s inability to meet specified guidelines has resulted in this situation."
