As a New Zealander who's been to Australia + a small handful of other countries I can vouch for Australia having a uniquely good convenience store dairy based drink industry. OAK is another old faithful brand I miss in NZ. Also Hungry Jacks (Burger King) there uses cream instead of milk in the soft serve and it's noticeably better.
The $1 coffee from 7-11 was my go-to drink in Australia. Came with the added bonus of annoying the hipster coffee snobs in melbourne when I was walking down the street holding a 7-11 cup. Damn fine coffee.
7-11 has surprisingly good coffee in the US too, or at least Texas. There was a 7-11 on the corner of the block I use to live on and drive past to get to Starbucks until I was running late once and decided to just grab the first coffee available. Now if I just want plain brewed coffee I'll find a 7-11. And if I'm wanting something more Starbuck-ish but don't want to deal with the morning rush, I'll go to a 7-11 and mix little over half a cup of the brew coffee then top it off with their hot chocolate.
I am not a coffee hipster (as will probably become evident by my next statement) but I do like good cafe coffee here in Melbourne and I completely agree. I don’t make it my daily driver, but 7/11 and even McCafe coffee is quite decent here IMO
