Apart from family and my own number about the only one I can think of is the Reading Writing Hotline (1300 655506) due to the sheer amount of their radio ads I’ve heard over the years while driving around.
Even within family I’ve only got one left that actually works though - Dad hasn’t changed his mobile number since circa 2000 but Mum did at one point and I never remembered her new one.
The societal reaction though would be very different and in favour of the woman. For an example a few months ago some English tourist was in Sydney, got annoyed at some guy waving a flag around her, sucker punched the guy in the head from behind, and received one punch back plus a free broken jaw as her prize.
Now check out how it was reported - it’s all about how bad it was for the man to punch a woman and the pretty important fact of her assaulting the man before getting said punch is mentioned once in passing (and it being a punch from behind with the man not aware is not mentioned at all, which is relevant because this is normally highlighted as a ‘coward punch’ in Australian media).
