It looks busy but takes in about 6 degrees of longitude and 4 degrees of latitude so it's a pretty big area for a VFR aircraft at 100 knots so plenty of time to change frequencies. 4 CTAFS & 2 Centre frequencies isn't too bad in a 60,000 square mile area.
Flying into Kununurra is not a problem, however, if you want to fly around the Bungle Bungle, there is a section in ERSA under Special Procedures on this.
When I did it, it was also advised to go and have a chat with one of the local tour operators which I did and they were particularly helpful.
For the Bungle Bungle scenic leg I input GPS way points on my AvPlan. This made flying the scenic route very easy.
Did it yesterday Doug. Tell us about your last flight
I did both (looked at special procedures and spoke to a local pilot), however there are very few flying tourists at the moment and had it all to myself...
