Just 38 of the 62 players who survived the cut had finished their rounds and officials instructed the remaining 24 to finish their rounds early today.
Jarrod Moseley was leading the field at 16-under-par after 10 holes when play was halted. Two-time Australian Open winner Aaron Baddeley was in second spot at 14-under with Peter Lonard a further three shots back.
Moseley said tournament officials had done the right thing by calling off play.
"It was a good decision and a credit to the PGA," he said.
The clubhouse leader was Nathan Gatehouse who shot a 68 for a 54-hole total of six-under-par 210, one stroke clear of Peter O'Malley and Rod Pampling.
Baddeley trailed Moseley by one shot at the start of the day but seized the outright lead when he eagled the 507m par-5 fifth hole.
Moseley responded immediately with a birdie at the next hole then moved back in front when he birdied the eighth.
