377, those comments whilst mildly amusing are totally incorrect. The CASA aerodrome inspectors have a requirement to maintain surveillance on all certified airports regardless of proximity to comfy hotels or being serviced by preferred RPT carriers.
The fact is though, that just like everyone else, they too have budgetary constraints that may preclude them going to every airport, every year. Much like FOIs who maybe miss an audit on a charter or training operation. The squeaky wheel, or one that has a few NCNs on the books will be their focus of attention.
