It's true in terms of Bernard Collaery / Witness K, but this is not the same at all. The entity being "hacked" is the ABC, which is an independent broadcaster that the government of the day is constantly trying to claim is biased against it. There is no reason to think that the CDPP or the Attorney General would try to defend the ABC from something like this. If anything they would point and laugh, and use it to justify another huge budget cut.

In terms of responding to criticism in the digital realm, you can get a pretty illustrative view of the situation by looking at how the Digital Transformation Office handled feedback to its pile of steaming shit of a coronavirus proximity alert app. Numerous researchers found serious flaws constantly from its first release. It took like 6 months for them to even recognise that any outside researchers had even been helpful, IIRC. Release notes were like "fixed bugs" and then the researchers decompile the .JAR again and say "nope, you absolutely did not fix this huge problem" and then find another one. Meanwhile the government sank millions more dollars into BCG consulting to review it, while these people were working for free and getting no credit. I think their campaign to cast doubt on the app's safety, efficacy and security was successful, and it did not get taken up, and then the report that was due to be published about the project was never released, and it was all swept under the rug. Overall I think it was about $10 million spent for in the vicinity of 5 covid cases identified, I don't remember exactly but I think all of them were also identified by phone interviews.

They did not, however, prosecute the researchers. So, ignorant and unkind, but mostly not like that journalist in the US who enraged a governor to the point of being criminally investigated for opening a webpage.
