Well I've been skiing in Australia so it does get cold there in parts. The center, northern parts of the country get to 100 F+ easily on the other hand, and some areas have no speed limits.
My guess is the Aussie version engines have standard oil coolers hence the 10w30 recommendation.
The American V-8s had to modified to run on leaded fuel in '97-'98 when I was there. Not sure if this is still true.
