Would that experience have been different if I wasn't an Australian?
The usual refund conditions are “less than two hours of play, within two weeks of purchase.”
Not much you can do - if the machines decide you don't get a refund, well, then you don't. I haven't bought anything on Steam since.

Ironically because speed-running requires a lot of practice this often means purchasing two copies of the game - the first to practice with, and the second to be (potentially) refunded!
There should be some sliding scale where you can make a great 2 hour or less game without the risk of infinite refunding (perhaps the game could be marked with a "half-way" point, etc, though that would involve the shop actually playing it).
I bought 2 copies of a game advertising co-op to play with a friend, only to discover it's local-only. (Steam didn't have separate "local/remote play/online co-op" labels yet) I opened a ticket and they refunded me as a "one time exception".
I suppose I could have invested time to diagnose the original issue (drivers, OS upgrades, etc). But, it was good to see that Steam just refunded without insisting it was an issue on my end (which, it may well have been, given the disparity of Linux systems).
They refunded my game after a short and polite message without any fuzz. I said thanks by buying a different game instead. Shame for the dev yes, but it was already an older one, that the developers moved on from years ago, so I didn't felt too bad about that.
Updated after your update: In this case I think we can assume "acceptable quality" has already been established by Nintendo's QA department. Its not an open store after all.

They've actually published games with Nintendo before, so they discuss how such terrible games were allowed on the shop in the second video
If you take a game back to a major retailer like Target or Big W, they won't accept it with the seal broken unless you tell them there is something wrong with the physical disk or cartage. They won't accept a return if you just tell them you didn't like it. (in my experience - also not an expert on this either)
The Nintendo online market pretty much has no oversight anymore. They don't do any careful pruning of shovelware these days.

NES games often had some pretty rough translations, but I can't think of a single game in that era that was this garbled.
