Broadcast Area and discrete frequency for Tyagarah, Murwillumbah and the Gold Coast flying training area

Closed 3 Jun 2021

Opened 5 May 2021


The Office of Airspace Regulation is proposing a Broadcast Area and discrete frequency in the vicinity of Tyagarah, Murwillumbah and Gold Coast flying training area. 


Aircraft are currently required to transmit on 126.7 MHz when operating within the vicinity of Tyagarah, Murwillumbah and within the Gold Coast flying training area, including danger area D656A-D.

Aircraft operating from further afield are also required to transmit on 126.7, including Kagaru (Archerfield’s training area), Morton Island, Grafton/South Grafton, Tenterfield, Stanthorpe, Inglewood, Pittsworth, Millmerran, Clifton and Gatton areas.

A mix of operations including parachute operations, recreational aircraft, gliders and gyrocopters operating from the Tyagarah aerodrome as well as circuit training at Murwillumbah is adding to the frequency congestion.


It is proposed that a discrete Common traffic advisory frequency (CTAF) be established around Tyagarah and Murwillumbah and the Gold Coast flying training area.

The broadcast area would include the Gold Coast flying training area, the Tyagarah and Murwillumbah CTAF, and D656A-D. The vertical dimensions of this area would be from the surface to the base of the controlled airspace.
