I don't recall the RAAF being described as a "green leftist anti-establishment shame group" at any time during my decades of service in the RAAF. I am a staunch supporter of the ADF.
Airspace isn't being managed "for our national needs". It's being managed for the convenience of organisations that don't actually "need" that much of it. That's shown by how other countries manage their airspace. Australia likes to think its better and smarter, but it isn't. In my view, it actually results in the RAAF being less prepared than it should be to do its job.
And calling for compliance with the law is not 'low-grade muck-raking', at least not in the dictionaries I've consulted.
You'll have to explain your point about "Defence Australia" and "Department of Defence". I'm not aware of what "Defence Australia" is, as distinct from the Department of Defence and the ADF.
