Pictures of the interior of the Sentinel (on the web at
http://www.mheaust.com.au/Aust/Resea...sentinel13.htm ) suggest that Australian interiors (at least of the armoured rather than human variety) followed UK practice in using white paint. Elsewhere on the same site details of a Ferret C1947 also indicate that the later pattern of silver was also followed. Possibly though they stirred the paint in a widershins direction.
