Western Australia's Mark McGowan has shared a rare lighter moment during a coronavirus press conference, breaking into a fit of laughter over a kebab.

Following on from reports yesterday that a NSW man was fined $1000 for allegedly stopping to eat a kebab "mid-run" , Mr McGowan was asked if similar rules would apply in WA.

"I find it hard to believe someone was going for a run and then stopped to have a kebab," giggled Mr McGowan.

"They do things differently in New South Wales."

Even his sign language interpreter couldn't stop laughing at the suggestion.

After chuckling at the suggestion Mr McGowan said police in WA were largely concerned with minimising groups of people.

"There's nothing wrong with going for a run and having a kebab," said Mr McGowan.

"It's whether or not you're in a group. That is the issue."

In what was – for the most part – a serious press conference, Mr McGowan doubled down on his decision to move to a hard border closure for the state on Sunday night, arguing "extraordinary measures" are needed to protect residents.

"We're in a war. A kind of war we've never seen before," said Mr McGowan.

"It will be stressful and it will be difficult, but I need everyone to work together on this."

Mr McGowan also reminded residents that they should stay home unless performing an essential activity.

"Planned Easter holiday trips are no longer permitted," said Mr McGowan.

"Our police will continue to operate checkpoints and run mobile patrols over the Easter period, so please make sure you follow the rules."

WA recorded an additional 22 cases of coronavirus overnight, taking the state's total to 422.
