Hi there, just a quick question in regards to understanding the ERSA

Say I am trying to find the radio frequency to use for Sunshine Coast airport if I returned after airport hours. It then becomes a class G airspace and you use the CTAF 124.4? Or 126.7?

Also, would you be able to elaborate on the ground and cuircut area frequencies, and what frequencies to use during normally hours? There’s just so many different frequencies listed in the ersa it seems a little confusing.

Thanks in advance

When the tower is not operating, the appropriate frequency to use is 124.4. This is the aerodrome frequency response unit AFRU and also serves as the CTAF frequency outside tower hours.
