Mr Turnbull on Sunday appointed Mr Scott Morrison as treasurer, handing the conservative lawmaker the top economic job in his new Cabinet in an effort to mend party divisions following the ouster of former prime minister Tony Abbott.
Mr Morrison won both praise and condemnation as immigration minister for his ruthlessly efficient implementation of Australia's policy of turning back boatloads of asylum seekers arriving from Asia. Most recently, Mr Morrison had been tasked with steering through difficult welfare reforms as social services minister.
