We checked the road conditions into WA prior to leaving Kings Canyon. The Tanami Track is currently closed due to flooding at the Western end. It might open in time – or it might not. And the road wouldn’t be that flash when it does. So a new route to Purnululu is necessary.
We will now go up the Stuart Highway and do the left turn at Katherine , west to Kununurra and down to Purnululu. 500 -ish km further , but possibly days quicker given the flooding and road conditions. And over 1000 km less dirt !
Footnote: turns out that one of the gold mines at the western end of the Tanami is now a major covid exposure site😳…definitely happy with our change of plan !
