Troubled PwC Australia will bring on Gilbert + Tobin partner Karen Evans-Cullen as its acting general counsel, two years after she left the big four accounting firm and disparaged its ability to win major legal clients.

Evans-Cullen, who joins on secondment from Gilbert + Tobin, will stand in for Meredith Beattie, who has brought forward her retirement from PwC as it reels from revelations it used confidential tax advice it gave to the Australian government to help multinational tech clients minimize their tax.
