The portfolios held by disgraced Liberal MLC Anthony Fels have been re-distributed, with Serpentine-Jarrahdale MLA Tony Simpson and Agricultural Region MLC Bruce Donaldson taking over.
Mr Simpson adds Consumer Protection to his existing role as Opposition Spokesman for Forestry, Volunteers and IT and Communications.
Mr Donaldson, the Liberals' Fisheries spokesman, will add the role of Shadow Mid West Minister to his portfolio.
Mr Fels lost his position on the opposition frontbenches last week after the Corruption and Crime Commission found lobbyist and former Liberal Senator Noel Crichton-Browne - had written a parliamentary speech and motion backing a push by litigation funder IMF for the Government to compensate victims of the Finance Brokers scandal.
Mr Crichton-Browne was acting on behalf of lobbyist Brian Burke, who had been employed by IMF.
After dumping him from cabinet, Opposition Leader Paul Omodei labelled Mr Fels' actions unacceptable.
"It's totally inappropriate for any Member of Parliament to present the views of a paid lobbyist as their own," he said at the time.
