(It does salinate soil in Australia, btw..cite already provided)

No, it doesn't. What salinates the soil in Australia is too
complicated to get into here, it has to do with underground salt
deposits, the loss of native cover and the inability of the soil to
deal with all the water. The salt is already there, in vast
underground stores. See

what's going on.
