Australia's Rainfall: The Driest Inhabited Continent

Yes. Australia averages 469 mm (18.5 in) annually—the lowest of any inhabited continent. About 75% of the landmass receives <500 mm (20 in) per year. The interior (Outback) is arid/semi-arid, getting <25 mm (1 in) in places. Only coastal fringes (especially north, east, southwest) get ample rain. This aridity shapes ecosystems, agriculture, and water policy.
