In Indonesia it gets tricky, they will refer to young woman as mba (sister) and an older woman as ibu (mother, usually shortened to "boo").
Indonesian women get it, they rarely get offended by being referred to as "boo" because it's a sign of respect. Although I did hear about 4 women getting irate in a pub when they got the tab and the server had written "empat gendut ibu" on it (4 fat mamas). That pub hired waitresses for their looks and personalities and was pretty successful as a result but... they weren't that great on keeping track of table numbers and groups and who was buying what, so they'd write down a description of a group on their tab.
I've seen some expat ladies get really upset about being referred to as "ibu" or "boo" though. Problem is that the Indonesians, even when they speak English, tend to tack it on at the end of every sentence when they are speaking to someone they see as having higher status than themselves. Like "yes boo, we add the transaction amount to the balance boo, transaction code is 1010 boo".
In Australian cities men will still call each other "mate" especially because we are drunk most of the time and therefore we tend to forget each other's names. But it is rare these days for women to refer people they don't know as "darling" or "sweetheart", which used to be quite common. Last time I was in Melbourne a Tesla saleswoman called me "sweetheart", which was a bit of a flashback. And in country towns and smaller regional cities people will still refer to you as "sweetheart" quite often. Like if you order a coffee they'll say "that'll be $3.50 sweetheart".
