They were by far and away Brisbane’s most successful rugby league team and one of the greatest clubs in Australian history, having won a total of 24 premierships in their 86 seasons, including seven of the first eleven.

[1] With the introduction of the Brisbane Broncos into the New South Wales Rugby League in 1988, Valleys formed a short-lived joint venture with the Tweed Heads Seagulls playing under the name Seagulls-Diehards, winning the 1988 premiership.

[2][1] Perhaps the greatest ever year for Valleys was their 1955 success during which the side remained undefeated under the peerless leadership of fullback Norm Pope.

Their side features a number of representative players including Shenae Ciesiolka, Meg Ward, Ali Brigginshaw, Brianna Clark, Kody House and Lavinia Gould.

Following the Diehards departure for Caboolture, and eventual extinction, in 1995, Queensland Cricket purchased the ground and renamed it Allan Border Field.

Currently Valleys Juniors, who evolved from the BRL team in 1951, play full-time at Emerson Park, Grange, and have done so since gradually moving out of Neumann Oval in the early 1970s.
