On final for runway 16 the pilot noticed another aircraft on departure using runway 34. The climbing aircraft turned right immediately to allow sufficient clearance for the landing aircraft to continue its approach, however, the pilot elected to go around instead. During the go around the aircraft mushed onto the flight strip, broke off its nosewheel, nosed over and came to rest inverted 30 metres from the initial impact point. The aircraft entered the circuit without making inbound or circuit entry calls and because the wind was still directly across the strip, the pilot decided to use runway 16 which he had used for the take-off. Two aircraft already in the circuit, but using runway 34, were not sighted until a head-on condition had developed with one of them. During the go around, with the speed at about 65 knots, the flaps were fully retracted. Prior to this departure a dual check was completed as the pilot had not flown the Cessna 172 for 8 years.
