The detail is "where do they park?" The answer is they don't.
Shared on Facebook with the caption "Doing absolutely no favours to their international reputation, Americans have swarmed social media posts of Taylor Swift’s Melbourne concerts confused by a very obvious detail. Can you spot it?"
It's an article from the Murdoch right-wing paper "The Australian", so I won't link the original source.

Aerial photo of the Melbourne Cricket Ground, surrounded to its North and East by tree-filled parks, to the West by a warm-up pitch, and to the South by a train line with two pedestrian overpasses over it. Underneath this photo is the article title "The MCG show detail that has American Swifties baffled" and byline "by Sam McPhee".
hey man if you had an eternal dark sky keeping you all nice and cozy then found out there was an entire universe of stars and planets and biology and shit out there you'd be a bit perturbed too.
I'm genuinely not sure if this is a serious question or if it's a much-improved version of the really lame jokes that I saw from Americans all over Facebook pretending to have no idea what cricket is.
Honestly? Yes, it's a much funnier joke than the ones I was seeing on Facebook. Those were all like "oh, crickets? Must be really noisy!" and other jokes pretending to think people were talking about insects. There were so many of them and they were all inane. This one about Parliament gave me a much better chuckle.
