Summary
The crew of VH-KDO were given a runway 16 Strathbogie standard instrument departure (SID) and were told to maintain 3000 feet. After take-off they were cleared to climb to 4000 feet.
Shortly afterwards, the air traffic controller noticed the transponder mode C altitude readout increase to above 4000 feet. When the crew were queried on the altitude deviation they promptly descended back to 4000 feet. However, a loss of separation occurred with VH-JQF, an Airwork aircraft, tracking in an easterly direction to the south of Melbourne and maintaining 5000 feet.
