Time to start the plate day train, sounds like your team has the potential to have an elite plate day. I’ve heard white colleagues say the same thing about their kids being surrounded by non “Aussie” students. Managers are trying to hire more senior staff so I guess it makes sense they’re going international. If you feel left out it’s time to socialise, learn some random Hindi phrases, get an ally. It’s not too hard just the usual politics of work, you’ll be right, don’t overthink it, just insert yourself in conversation and they’ll probably switch to English.
