Tasmania's NBL team received its name in the JackJumpers last week; chief executive Simon Brookhouse said the launch has resulted in a jump in terms of memberships.

"As we've said all along, it's [JackJumpers] for people all around Tasmania and Australia ... we've had members sign-up from everywhere and we're really keen to continue to do that," he said.

The JackJumpers are slated to play two games in Launceston for their inaugural season in 2021-2022.

While the Silverdome is the location of choice, Brookhouse said some work was needed on the venue for next season after meeting with site officials on Wednesday.

"It does need a bit of work to be NBL-ready and we'll certainly work with the [state] government to make sure we can do that," he said.

"Improving things like lighting for TV, corporate hospitality and those sorts of things - we need to look at how they can be done."

Brookhouse added that upgrades could cost anywhere in the vicinity of $500,000.

"But that also isn't going to just support basketball, it will support other events that go there and need TV whether it be netball or other indoor sports," he said.

Brookhouse said 2021-2022 preseason games were still planned for Launceston and the North-West.

"It may be we bring two teams down for two or three preseason games, and play them at places like Ulverstone, Elphin [sports centre] and Kingborough," Brookhouse said.
