The JackJumpers will call the DEC home for the 2021-22 season, which is slated to start in October next year.

The $41 million revamp of the centre has started with its insides being gutted; tenders for the interior re-works will close December 21.

NBL owner and executive chairman Larry Kestelman made his first physical appearance at the site in months due to COVID-19.

He was optimistic that the centre's revamp would be complete on-time despite the six-month delay caused by the global pandemic.

"It was always going to be tight, and a six-month delay from COVID has made it tighter ... but we as a team are up for it," Kestelman said.

"We'll make sure that hell or high water ... this venue is up and running for the October start of the season."

Kestelman added that while he believes the new DEC will be complete with time to spare, he's ready for an eleventh hour scenario.

"As long as it's ready the day before they [JackJumpers] play ... we'll make sure that happens," he said.

The NBL head honcho said he was pleased with the groundwork the franchise had already made in the state, with 2500 members already signed on.

Arrangements are being made for temporary training facilities to be available for the JackJumpers before and during next season.

Kestelman said a long-term team facility will be co-developed with the state government across the next two years.

"The DEC will not be a permanent training facility ... even though we'll have courts down when we can," he said.

"For me, the plan is for this venue to be too busy to have them training here on a regular basis, quite frankly."

JackJumpers chief executive Simon Brookhouse said he anticipated a head coach for the team to be announced before Christmas.

"In a perfect world I'd love to have someone here early in the new year ... but we have to look at people's contracts and [see] whether or not we can make that happen," he said.
