I'm the first to be critical of AsA management and am aware that CASA is a spineless organisation at the moment (doggo staffing, launy tower hours etc), but CASA aren't responsible for holding AsA to account over staffing. So long as all processes are legally complied with CASA won't care about TIBA airspace, just like they don't care when Airlines cancel services. It is up to the customers & shareholders to hold management accountable.
