GA International Ops from non Intl Airport
Digging around the Australian Customs website it says that under certain situations you can depart on an international flight from a non international airport....if you fax them passport details a week in advance and the itinerary and they will/may approve the operation.
Considering Sydney Intl is impossible to get a slot.
So....if you had your own airstrip, say in the southern highlands near Golburn and wanted to travel to NZ, you could enter in an agreement with customs to do so on a regular basis. On the website they even have the right forms to download and fax back.
Have i interpreted this info correctly?
