Summary
An unidentified aircraft, later identified as VH-JEB, was observed inside the Melbourne control zone in the Sunbury area on a south-south-easterly heading. The mode C readout showed the aircraft was at 1900 feet. At the same time, VH-CZU was becoming airborne from runway 27 on an "Avoca one" departure. VH-CZU was instructed to maintain runway heading and asked to look for the other aircraft. The crew of VH-CZU sighted VH-JEB and passed two miles in front of it and 200 feet higher.
The pilot of VH-JEB reported that he had become distracted after initiating a diversion back to Essendon due to concern about fuel reserves. He was conducting a solo navigation training exercise.
