The pilot of the Mooney was an IFR pilot who should have been able to establish, from the information available, that Tamworth control area was class "C" airspace above 4,500 ft. He should also have known that he required an airways clearance prior to entering class "C" airspace. Had the pilot requested a clearance on any of the frequencies referred to in the ERSA or depicted on the charts, he would have been provided with the correct Tamworth ATC frequency on which to establish two-way radio contact and obtain an airways clearance. Two-way radio contact between Tamworth ATC and the pilot of the Mooney would have enabled Tamworth ATC to apply separation standards in accordance with MATS.

The relevant AIP's did not specify the vertical boundary between Tamworth control area and the overlying Brisbane sector. That omission may have made it difficult for the Mooney pilot to determine the correct ATC frequency on which to establish two-way radio contact with Tamworth ATC.

The Brisbane sector controller did not provide traffic information to Tamworth ATC about the Mooney because he had no reason to suspect that the Mooney was in Tamworth controlled airspace without an airways clearance. Provision of facilities that would have enabled Tamworth ATC to better determine the disposition of aircraft within and around Tamworth controlled airspace may have assisted Tamworth ATC to provide a separation standard between the Mooney and the Saab.
