Community sporting activities will be permitted to have up to 20 people in undivided spaces from Monday, June 1.

Victorian Premier Daniel Andrews announced the change on Sunday as part of a relaxation of COVID-19 restrictions.

While groups increase from 10, gatherings must remain non-contact with participants staying 1.5 metres apart.

No formal competitions are permitted.

North Ballarat City senior football coach Shane Skontra welcomed the relaxation.

He said while there was some way to go, it was a move in the right direction.

Skontra said the change to bigger groups opened up scope and flexibility for training drills.

He said at the moment North Ballarat City was planning for two weeks at a time, given the uncertainty of the path ahead.

Skontra said training structures would depend on whether the new conditions allowed two separate groups of 20 on an oval at the same time or just the one.

As for netball, Ballarat senior netball head coach Rachael Cross said the increase in group sizes would help facilitate weekly training sessions.

She said with current sizes limited to 10 people, she was forced to bring groups in one at a time.

"I've got 24 girls in my junior squad and I would have had to do three hours of training," she said.

"It would have been hard for me to run multiple sessions, because I would have had to split the girls up which makes it hard to work on combinations.

"This gives us a lot more leeway."

Cross said the Swans would resume training as of Thursday and had made preparations in compliance with government restrictions.

Swimming pools will also be able to open from Monday, June 1, with limits of 20 people.

Meanwhile Mr Andrews said indoor facilities, which house sports such as basketball, volleyball, table tennis and badminton might reopen from June 22, if community transmission rates continued to remain low.

He said facilities would open for up to 20 people per space and up to 10 people per group or activity at any one time.

Basketball Ballarat chief executive Peter Eddy said he was pleased the government was acknowledging the need to get indoor sport back within a timeframe that was safe for everyone.

"We view what he said today as a real positive, and it does give everyone a sense of ongoing encouragement that things are happening and there is light at the end of the tunnel," Eddy told The Courier.
