After pushing the button on the last post I received this …

This is the road to the Broome Bird Observatory and that’s the warden checking the depth to which it’s flooded. It would indeed be a great adventure and yes it would be illegal. There are big penalties for driving on closed roads. To get to that point from the highway may well have taken you through worse!
The forecast for the next few days is warm and dry. It will soon reopen but it will still be an adventure – 4WD only for a while.
