Having been there for the 3 days, I think you're a bit harsh Skip.
For me, the Security controlled airport thing is a non issue, the event wasn't airside - we camped next to the plane, with toilets and showers on site, breakfast included all for $20 for 2 adults.
It's 500m from the terminal to the event site, I was suprised they actually had a courtesy bus at all. 10mins must have been a leisurely stroll. The Courtesy bus also took you into Parkes for shopping, lunch, dinner etc.
There was a truck watering the taxiway to the event site to keep dust down.
Food vendors on site.
Breakfast and Dinner provided by the local Rotary club
Bar and evening Campfire
Toilets and Showers
Ground marshalling for those parking airside.
So clearly some thought has gone into the event to make it easy for attendees.
The pilot instructions issued were good enough.
Flying in - we all new it was going to be busy, it's uncontrolled airsapce. I was 5nm out when there was 2 in the circuit, 2 more joining and an RPT on a 10nm final for a different runway. We all communicated and sorted ourselves out.
We had a lot of the general public come and talk to pilots in the camping area. Most loved the idea of flying somewhere and camping next to the plane, all good promo for RA.
Yes there should have been more RA focus and less GA stuff. GAP having 3 Sling TSI's was a bit much. The variety of the european plastic fantastics was good to see, prices a bit eyewatering though.
Overall I thought the event was good and would go again.
Narromine is in the past, time to move on.
Was it bad? IMHO, No.
Can they make the event better, most likely - they have improved on 2022 so indications are they will.
