Stinky. Around 1999 from memory, the then Cape York mail service was not permitted to carry passengers as the service was deemed by CASA to be an RPT service in accordance with CAR206(1)(c). Many passengers were inconvenienced for some weeks whilst the operator obtained an RPT AOC - at very significant cost.
Today I understand the service is deemed by CASA to be a charter service in accordance with CAR206(1)(b) as the service is not available to "persons generally", only Cape York station employees.
Inexplicable.............!
