Hmm… moon circumference is 10Mm, Australia width is 4Mm, so you can lay 2½ Australias end-to-end when wrapping them around. Figuring out any 2D tessellation is left as an exercise for the reader. But the process of wrapping them… well, the biggest earthquakes on record only damaged half a dozen buildings and structures, to a few million dollars’ damage; this process might just cause rather a lot more. Like a zillion Australias divided by a Tahiti or so, that many times as much. Yeah. It’ll surely also depend on what depth you peel the Australias at.
