On 8 March 2013, the crew of Qantas A330 descended below controlled airspace and to within 600 feet agl when still 9nm from the landing runway at Melbourne in day VMC after mismanaging a visual approach flown with the AP engaged. An EGWS Terrain Alert was followed by an EGPWS PULL UP Warning and a full recovery manoeuvre was flown. The Investigation found degraded situational awareness had followed inappropriate use of FMS modes and inadequate monitoring of the aircraft flight path which had occurred in the context of insufficient provision of Operator guidance on how to fly visual approaches
