Many of the cars produced by Nuffield, BMC and Leyland in Australia were the same as their UK counterparts.
But not all of them were. Some were only slightly different (as in the Morris Marshal) some were substantially re-engineered but closely resembled one of the UK versions in appearance (such as the Wolseley 24/80) while others were unique to Australia (such as the Leyland P76).
