Wrong Frequency at Mudgee?
All right, I'd be the first to admit I don't have a pilot's licence and therefore shouldn't be entitled to an opinion on procedures out in the GAFA but I have heard tell many a tale of sweaty-palmed arrivals at Mudgee, or Dubbo for that matter.
SOP for aircraft that don't transfer to the correct frequency for one reason or another is for ATC to make a broadcast on your behalf. If you're going from one area frequency straight to CTAF then we'll pass traffic to all inbound IFRs and any VFRs we know about. Still doesn't cover all contingencies but it's still better than nothing at all which is what some people believe we're doing now.
Be a bluddy good job if wasn't for all these pilots asking for stuff all the time...
