The Coalition of Major Participation Sports ACT, the union of all Canberra's major sports, wants the government to create a long-term plan around what facilities will be built, where they'll be built and when.

That's so they can plan and try to find alternatives to any facilities shortages.

The Canberra Times revealed Basketball ACT was planning to sell their block of land - next door to their Belconnen Stadium - because they've been unable to get any government funding to build new courts they desperately need.

That's despite paying almost $600,000 in rates over the past decade.

Basketball's enjoying a participation boom, further fuelled by Patty Mills and the Boomers' historic Olympic bronze medal.

But they're struggling to get enough indoor court time to get everyone a game.

Basketball ACT chief executive David Simpson was fearful it would lead to players walking away from the sport.

COMPS ACT - made up of basketball, Australian football, cricket, soccer, hockey, netball, rugby league, rugby union and tennis - wants the government to come up with a planned timeline for all new facilities throughout the ACT.

As revealed by The Canberra Times, the government's current solution to the indoor court crisis was to build new facilities at new schools.

But Simpson said that wasn't the solution. It still wasn't enough to keep up with the growing demand.

"We're advocating the election promise of a facilities strategy being undertaken by the government and actually having some strategy around where facilities are built and when facilities are built, and what the investments are - based off more than just the current way it appears to be allocated," he said.

MORE CANBERRA SPORT

And what was the current way? Simpson felt it was ad-hoc and didn't meet sport's needs.

He said it was a constant cycle of sports going to the government cap in hand asking for funding.

A clear strategy would solve that.

"It is [ad hoc]. We all have needs. All the indoor sports have a need for more courts and we're putting our argument forward and hoping we can get some funding and we can get some relief," Simpson said.

"But there just doesn't seem to be enough strategy around which sports are getting funded at which time.

"That's probably what we're looking for. Even to have it mapped out.

"If basketball's not going to get facilities for five years tell us and then we will look at what our options are.

"But the current process of us going to the minister on a regular basis and saying please can we have some funding or if an election comes up we try and get an election promise out of the government it doesn't provide any structure or sustainability for us."
