Another Labor reshuffle could be on the cards with Stinson, a former journalist who was elected to the marginal seat of Badcoe at the 2018 election, departing the shadow ministry.

She was immediately elevated to the frontbench after the election, and appointed to the Child Protection portfolio, but switched to Planning, Local Government, Arts and Multicultural Affairs in last year’s reshuffle.

In a statement, she said: “Today I’ve resigned from the Shadow Cabinet in order to deal with deeply personal matters.”

“These deeply personal matters have been distressing and I’ve decided to step back from the frontbench to give myself time to deal with this.

“I want to thank Peter Malinauskas and my Labor colleagues for the honour of serving in the Shadow Cabinet and for their support at this time.

“I look forward to continuing to serve the community I love in Badcoe.”

It’s understood she intends to recontest the seat at next year’s poll.

Malinauskas thanked her “for all her hard work and achievements across her portfolios”.

“Jayne is an outstanding Member for Badcoe and I know she will continue to work hard and passionately serve her community,” he said.

“Her decision to step back from the frontbench will give Jayne the time she needs to deal with her personal matters.

“She will continue to have the support of the Labor team as she deals with these personal matters.”

Labor’s caucus will meet in coming days to elevate a new frontbencher, who is likely to hail from the party’s Right faction.

The ALP also has a national commitment to elevating women, meaning the likely candidates are Legislative Councillor Emily Bourke, who is currently overseeing Labor’s Adelaide candidate Lucy Hood’s marginal-seat campaign, and former media union secretary and senator Dana Wortley.
