If these operators want to get away from complying with Australian rules or oversight they should not be allowed to operate in Australian airspace.
SRM,
If that was the case, ALL overseas airlines and many other operators would be barred from Australia, because Part 129 AOC holders only have to show compliance with ICAO standards, not Australian regulations.
Indeed, some airlines might uncharitably suggest that they wouldn't lower their standards to comply with "Australian Rules".
Heavilift Cargo Airlines has consistently passed ICAO IOSA audits, something with which some Australian airlines have had a problem ---- so what does that say about "Australian Rules".
Tootle pip!!
