SYDNEY (AFP) - Former Australian Test prop Ewen McKenzie was installed on Tuesday as the new Wallabies coach, vowing to stamp out ill-discipline and deliver consistent success, after Robbie Deans quit following their series loss to the British and Irish Lions.

McKenzie, who will face his first Test against the world champions New Zealand in Sydney on Aug 17, said he was humbled to get the nod.

Deans, a former All Black, quit earlier on Tuesday after five years and 74 Tests following Saturday's humiliating 16-41 thrashing to lose the British and Irish Lions series.
