I don’t know if it's a scam or not as I don’t speak Mandarin, but I keep getting robocalled from a group of numbers, all apparently from NSW, that all leave similar voicemails that start with ‘press 1 for English or 2 for Chinese’ then an 18-20sec string of what sounds like Mandarin.

I don’t want to just blanket them as scam as I do occasionally receive wrong number calls from Mandarin speakers, & they at least were legit - my number is a single digit different from whoever they were trying to call - so I’m tending to give these robocalls the benefit of the doubt in being a legit organisation, & simply spam rather than outright scam.
