New Labor leader Bill Shorten has unveiled a 30-member frontbench line-up with Tanya Plibersek as deputy and 10 other women.

But the team is the result of heavy factional manoeuvring with the personnel merely rubber-stamped by caucus after the right and left groupings met earlier on Monday to allocate positions.

Of the 11 women, the Right faction provided just three and none from Victoria. Portfolio responsibilities will be announced on Friday. Mr Shorten will be joined in the four-person leadership group by Ms Plibersek, and Penny Wong as leader in the Senate. Right faction warrior Stephen Conroy is her deputy.

The positions were worked out as part of a factional power-sharing deal which meant the Left got the deputy leader's position and leader in the Senate, after the Right secured the party leadership.
