Subterranean Waters of Australia. J. Gustav Richert.

Subterranean Waters of Australia.

Stockholm: Almqvist & Wiksells, 1917. Paperback. References the work of Gunnar Andersson who reported on the peculiar hydrological conditions of Australia, the alarming decrease of the capacity of the wells in the great artesian districts. Two very different opinions developed about the water - J.B. Henderson who considered the wells fed by rain water and J.W. Gregory, who said they are chiefly "plutonic waters", stored in the underground during preceding geological periods. In May 2019, in central Australia's Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, water discovery in an ancient underground valley has boosted hopes of development in APY Lands. "Department for Environment and Water senior hydrologist and project leader Adrian Costar said the water was a significant find... that came from a "palaeovalley" — an underground valley where the groundwater was deposited below the surface. Core drill samples have been dated at between 5 and 10 million years old." (abc.net.au). Seems that J.W. Gregory was correct.
