The newly-elected Liberal Party leader is in isolation, releasing a statement last night saying he tested positive to a rapid antigen test yesterday after developing “mild symptoms”.

It comes just days before State Parliament resumes on Tuesday, meaning Speirs will likely miss his first sitting day at Opposition Leader.

“I am thankful that I feel fit and healthy, aside from a scratchy throat, but will now isolate for seven days in line with current SA Health rules,” Speirs said in a statement.

“I am in the process of communicating with everyone who I have met with over the past two days and encouraging them to get tested where appropriate.

“I will continue to work from home as my new Liberal leadership team starts to develop a positive alternative vision for the future of South Australia.”

Meanwhile, West Australian Premier Mark McGowan is set to re-emerge from COVID-19 isolation as the state winds back face mask and vaccination mandates.

The premier says he is feeling better and will exit quarantine on Thursday, having tested positive to the virus last week.

One of his teenage sons has also recovered after being hospitalised with COVID-19.

Federal Opposition Leader Anthony Albanese’s home isolation is set also to end as he recovers from COVID-19.

The Labor leader tested positive to the virus last Thursday, forcing him off the election trail for a week while he campaigned from the confines of his Sydney home.

Albanese will fly to Perth today ahead of the party’s campaign launch on the weekend.
