Upper house MLC Walt Secord,who served as chief of staff former Labor treasurer Eric Roozendaal,will become shadow treasurer,while retaining the Arts portfolio. His promotion comes despite the fact he backed Ms McKay's rival,Kogarah MP Chris Minns,for the Labor leadership.
The appointments come ahead of a caucus meeting on Tuesday,where MPs will vote on key party executive positions. It is the first caucus meeting since Ms McKay'svictory over Mr Minns in the leadership ballot on Saturday.
Ms Catley and Ms Sharpe,both members of Labor's Left faction,are expected to be backed for their respective roles by the Right faction at the meeting.
It follows a meeting of Labor's left caucus on Monday afternoon toresolve a looming split in the faction,after Ms Sharpe declared her intention last week to nominate for deputy leader.
