What would rolling heads actually achieve here? IMHO - there “just” needs to be stronger regulation that ensures carriers plan and account for this.

The regulation is already there, mandating the telco routes 000 calls. They failed and as a result people died.

What the parent poster probably means by rolling heads is, this should not just be a fine to the telco but literally people going to jail for the criminal negligence.

How else is there going to be change? A money fine is just an operational expense that can be offset and "part of business if someone dies because of bad testing".

Why would anyone take the *existing* legislation seriously if they don't stand to lose something if they don't live up to it? Individuals need accountability, or they know a fuckup like this just needs a ChatGPT script read with a solemn face and they can go on with their lives.

Optus has had three catastrophic incidents in as many years, there is a clear failure of management and rolling those heads would make room for people not keen on repeating history.
