Warrnambool Basketball's Mike McGorm says junior players will be "shattered" after the snap state government lockdown forced it to cancel this weekend's junior seaside tournament.

Teams from across Victoria had submitted teams for the under 12 and under 14 two-day competition

"I am as flat as a tack to be honest," he said.

"I am really disappointed. My (under 12 team) I train we've worked hard, outdoors we've put in the time and energy and those little buggers will be shattered.

"Our whole livelihoods have been put in jeopardy for a tennis tournament (Australian Open), it's beyond maddening."

McGorm said attention now turned to what to do next.

"We may re-schedule, I am not sure," he said.

"As a committee we'll sit down and discuss the pros and cons of moving it."

McGorm said the lockdown, which is in place until Wednesday at midnight, could impact more events if it went longer.

"It puts in jeopardy country champs, state selection," he said.

"We missed all these events last year."

Western District Bowls Division will cancel its Saturday and Tuesday pennant rounds.

Secretary Marian Treweek said it was the most logical option.

"The phone has been running hot," she said on Friday afternoon after Premier Dan Andrews' lockdown announcement.

Listen to the latest episode of our weekly podcast The Booletin and Beyond:

"The complete round will be cancelled and we'll plod on from there.

"If we extended the season and pushed the round out, one - people get confused and two, it (a lockdown) could happen again."

South West Cricket Association president Kym Mathew says he's waiting to hear from Cricket Victoria on what will happen to this weekend's round of matches.

It's round 16 of division one.

He said SWC would do what Cricket Victoria and DHHS recommended.

"I would imagine from the face value of it, I think the round would be a wash out," he said.

Each side gets three points each for a wash out.

He said he had already had enquiries from clubs asking him what would happen on Saturday.

Shipwreck Coast Swim Series committee member Martin O'Brien said the final leg of the event at Port Campbell might be rescheduled.

"At this stage we're proposing to run it next Saturday but just waiting for that to be confirmed," he said.

O'Brien said the group was waiting on host Port Campbell Surf Life Saving Club to give the green light on that idea.

The race was earmarked for Saturday, February 13. The first two legs were in Port Fairy and Warrnambool in January.

He said the committee would post on its Facebook page as soon as it had an update.
