I happen to be in a valley were there is no cellphone coverage, and I have no need of one outside my home, so I am entirely dependent for phones and the Internet on my broadband line. Everything comes down that 'pipe'. If it is down, I have nothing: no phones, no email, no Internet--nothing.
My line went down on the 27th of July 2022, and did not come up till the 30th of August. That meant that I was without access to everything, unless I travelled somewhere to borrow someone else's phone fixed or mobile or get limited access to the Internet on a library computer (which did not give me access to vital accounts, was a three-hour round trip away, and sometimes Chrome was not working on it).
But on that computer I did come across this, section 157 of the Crimes Act 1961:
157
Duty to avoid omissions dangerous to life
Every one who undertakes to do any act the omission to do which is or may be dangerous to life is under a legal duty to do that act, and is criminally responsible for the consequences of omitting without lawful excuse to discharge that duty.
