Non clickbaity version: they did not “jump” anywhere, the coordinates for GPS were just updated for the first time since 1994 to account for the constant movement of 7cm per year. And it’s not just these 2 parts of Australia, it’s all if it. NSW and Victoria just moved slightly more than the rest (1.8m vs. 1.5m or 1.7m for other parts).

Which I guess means Australia is also rotating slightly clockwise?

  there's a map in the article pp misunderstood where nsw and vic are, so it's going more anticlockwise than clocwise.

    On the map in the article, the left seems to be moving up faster than the right -- isn't that clockwise?

if you're relying on that map, it's an old one not current with the text in the article actually, victoria and nsw moved only 1.5 m in it, less than average and certainly less than the areas that moved the most, which are parts of the northern territory and western australia. that map was produced a few years ago, when gda2020 was defined. since then, victoria and nsw have moved about another 14-21 cm, hence the 1.8 m figure. i think there's a little padding included too to account for future drift. as to the question of if these two states alone jumped, yes, they would have, if you have a datasink that collects official maps and collates them. roads that align on the ground might not meet on your map, since victorian data is gda2020 and south australia is gda94. how do you deal with that in real life? it's a real concern to real people, and it is not clickbaity to report it. the article did a good job of explaining how it matters to a normal person, but not a good job of explaining why it matters. that is the correct criticism.

Not quite: "To fix this, all Australian states and territories have agreed to update their coordinates by June. However, they are all doing it at their own speeds. On January 1, the Victorian and NSW governments updated the coordinates of every road, property and geographical feature in their states, essentially moving the south-eastern seaboard 1.8 metres north-east overnight." So all of Australia will move by June, but so far only NSW and Victoria have. I don't see why it's a good idea to update coordinates of different parts of a continent at different times. Likely a political decision, not a technical one.

  It sounds like it wasn't an explicit decision, they just have different people working on it and the NSW and Victoria people were able to make the change earlier than others.

  The complaint was towards the clickbaity title which leads one to believe there must have been a sudden tectonic event that caused the continent to move. “Florida man jumps back in time by one hour!” - leap hour reporting.
