The final piece has been laid in Ballymore’s long-awaited upgrade puzzle after the Queensland opposition promised to match the $15-million Labor commitment already on the table if they win Saturday’s state election.

The Australian women’s Wallaroos rugby team would join the Queensland Reds at the $30-million National Rugby Training Centre to give the once-proud venue new life after years of decay.

The works, due to begin next year, are the first stage of a vision to turn the beating pulse of Queensland rugby union into a health and high-performance sporting hub.

Ballymore could house multiple sports if Brisbane’s 2032 Olympic bid is successful, bolster Australia’s 2027 Rugby World Cup hosting hopes and act as a training base for the Wallabies or touring Test nations.

The upgrade will feature an integrated stand to replace the existing McLean Stand, which was first built in 1968 and extended in the 1970s, as well as men’s and women’s changerooms and recovery facilities.

In 2007, then Prime Minister John Howard guaranteed a $25 million funding commitment, only for the project to be canned the following year by Kevin Rudd after Labor won the federal election.

Support from both sides came ahead of last year’s federal election, with a Palaszczuk Labor government promise earlier this month ironically nudging the LNP opposition into action on Tuesday.

“Securing a commitment from the LNP guarantees a project which has been more than a decade in the making,” QRU boss Dave Hanham said.

“It is also an important first step for Queensland in developing a 100-hectare community precinct for the Olympics, centred on Ballymore and the Newmarket sports fields to the north.”
