OK, missed this in the Cairns Airport GA charges:
The following discounts and surcharges will apply to all General Aviation landings:
0800-100 0800 - 1000nd 1400-1600: 15% discount
0300-0500 and 2100-2300 5% surcharge
2301-0259: 10% surcharge
1001-1359: $350.00 minimum charge for all recreational aircraft (i)
(i) Recreational aircraft are deemed to be aircraft not utilised for commercial purposes.
I guess that settles it - the aircarft is only used to facilitate commercial activities!
I doubt that a court will agree that a missed approach off the ILS constitutes a landing!
Tell'm to get knotted Floppy!
