Hi Tony,
My post heading should have read Newman to Hedland to Marble Bar, we went via the blacktop, hence the pic of a Tugboat.
A couple of days in Marble Bar, mainly coz we hadn't been before, but have found from locals and others that you can come in from Auski roadhouse with 65 k of sealed and about the same unsealed, OK for a van if you take it easy. Newman to Marble is a lot longer and rougher apparently.
