Jetstar A320 at Coolangatta on Mar 31st 2014, incorrect configuration for landing

A Jetstar Airbus A320-200, registration VH-VGT performing flight JQ-216 from Auckland (New Zealand) to Coolangatta Goldcoast,QL (Australia), was on approach to Coolangatta's runway 14 when the aircraft descended below approach profile prompting the crew to initiate a go around. The aircraft positioned for another approach to runway 14 and landed safely about 12 minutes after going around.

Australia's ATSB reported the crew had "inadvertently set an incorrect air pressure (QNH) on the Electronic Flight Instrument System Control Panel (EFIS), resulting in the aircraft being below the normal approach path." The ATSB rated the occurrence a serious incident and opened an investigation.

Radar data show, that the aircraft was below 600 feet measured to standard pressure (approximately 700 feet MSL measured to QNH) 3nm before the runway threshold on first approach before initiating the go-around. At that position a standard 3 degrees glidepath would require the aircraft to be at 950 feet AGL.
