The claim isn't about the age of rock, but that the surface has churned almost everywhere. Israel does contain the oldest measured continuous surface at about 1.8M yo, but nobody claims to have looked everywhere.

How churned is "churned"? Does this mean particular pebbles have have been found to have lain in their current arrangement for 1.8 million years, or just that not much has happened? I expect any arid region far from the poles or mountains and lacking dune fields will have similar patches of inert land. Much of Australia would fit this bill.
