Non issue at present, no traffic apart from Geelong Airport Circuit, Geelong Seaplane, One Jetstar Flight inbound at YMAV, One Rex(?) outbound at YMAV, one student on a practice RNAV approach at YMAV and the very busy Tiger Moths further North. Separation organised and/or confirmed by radio in each and every case.
I like to hear a voice on the other end as Professional as Mr. Jetstar, or at least sounding as concerned about the possibility of a mid-air as I am.
What worries me is the possibility of a member of the "No Radio" brigade or someone who doesn't think they should need to use it near the South Coast / going coastal, or is so situationally unware that they don't even understand that there might be a problem.
It's my guess that about 30% of the skippers I've raced against in yachts have a problem with "situational awareness", and blithely do the stupidest things you ever saw as a result. I just hope the proportion is way lower in aviation.
