The Diamantina "runs" from the southern side of the Selwyn Range at about 21 degrees South 141 degrees East, down to Lake Eyre at about 28 degrees South 137 degrees East.

The Georgina "runs" from Northwest of Camooweal on the Queensland-Northern Territory border at about 19 degrees South 138 degrees East and disappears in the Channel Country around Bedourie at about 24 degrees South 139 degrees East.

Eventually, if it's a good year, this water also finds its way down to Lake Eyre.

I say "runs" because it's only in good years that they have a lot of water, and very good years that much water gets to Lake Eyre.

For what it's worth, the Diamantina was named after Diamantina Roma, Lady Bowen, the wife of Sir george Bowen, the first Governor of Queensland after it separated from New Sout Wales in 1859. She was a very beautiful woman, by all accounts.
