oh no! that looks like a non-Australian plug. is that a US plug? I had (wrongly) assumed the US plugs would also be the same shape as the Aussie one. I’ll have to see if I can find some dimensions of them and redesigning. sorry for the inconvenience. if you’re able to measure the brick that’d be useful otherwise I’ll try to find dimensions online.

I've uploaded a new profile with a 2nd plate with the hope that it fits the US plug. Would love to know how close it is. I've followed the dimension of a website that shows the dimensions (as per this page https://www.chargerlab.com/review-of-new-apple-20w-charger-for-iphone-15-a2940/) .
