The ute appears to be a 1 Ton chassis , with 17" wheels . The 15 cwt models had a full length running board , right to the rear guards , whereas the 1 Ton model had the short running boards as seen in this vehicle . Look at the worn tyre on the front near side.... this ute has travelled many miles
Driver Tom must have been a keen photographer, because there are later pics taken by him in New Guinea , now a corporal but still doing the same job , spraying DDT on mossies !

Yes Tony , the base colour would be the darker green with the Light Stone applied with a brush
