The pilot of VH-HCE was preparing to conduct solo circuits and landings, using runway 11 Right. The aircraft had stopped facing northwards on the bitumen section of runway 36 Right, just south of taxiway Lima, while the instructor vacated the aircraft. The Piper VH-EMZ had previously landed and was taxiing westward along taxiway Lima. As VH-EMZ approached the runway 36 Right intersection, VH-HCE began to cross taxiway Lima, heading towards the holding point for runway 11 Right. The two aircraft collided in the middle of the taxiway. The pilot of VH-EMZ subsequently reported that she had difficulty seeing along the taxiway because of the late afternoon sun. The pilot of VH-HCE reported that he had looked along taxiway Lima prior to moving forward, but had not seen the other aircraft.
