Redmond unveils new shadow cabinet

Isobel Redmond has issued a stern warning to the South Australian Liberals - grow up, stop the infighting and get on with the job.

The opposition leader unveiled her new-look shadow cabinet of 15 on Wednesday, rebuking her team over the internal warring that has consumed the party since it lost the March 20 election.

"I think we need to show more discipline as a party - I think that's one of the strengths of the Labor Party that we need to learn," she said.

'Silly disputes'

"I think the wider Liberal Party and the wider community expect us to grow up and get on with the job and not be into these sorts of silly disputes."

Former deputy leader Vickie Chapman - suspected by many of being at the centre of the turmoil - was stripped of the prestigious attorney-general portfolio.

Ms Chapman had barely disguised her desire to lead the party, refusing to rule out contesting Ms Redmond in the last week of the election campaign.

She now has carriage of families, housing, disability and ageing.

Ms Redmond, who made it clear weeks ago that she would be the sole person to decide on the new cabinet, denied it was a demotion.

Chapman 'not demoted'

"I haven't demoted Vickie Chapman, I've given her some extremely significant portfolios," she told reporters.

But she conceded Ms Chapman had been dropped down a peg or two.

"I look at it like a football team, if you don't get the front row, you get the next row and that's what you do - you do it because you're part of the team," she said.

The opposition leader also denied recent infighting over her deputy's job - which saw three people hold the position in just eight days - had impacted her choices.

Costings gaffe behind Griffiths

Ten of the new cabinet are from the House of Assembly, while five are from the Legislative Council.

Former deputy leader and shadow treasurer Steven Griffiths, who made a costings' gaffe the day before the election, will now oversee economic development and transport and infrastructure.

Martin Hamilton-Smith, dumped on Tuesday as deputy after just one week in the job, thought he was getting transport, but ended up with industry and trade.

New deputy

New deputy Mitch Williams has hung onto his preferred portfolios of water, energy and resources.

Ms Redmond's preferred choice for deputy, another former leader Iain Evans, will take on the government's formidable deputy Kevin Foley as shadow treasurer.

Decisions on whether the Liberals will form "factions" similar to Labor will be made before the first sitting of parliament at a date yet to be set.
