Going Boeing, Don't know what aircraft you're using as a reference, but I was under the impression Autolands can be made in a crosswind of 25 knots...
747-438, the aircraft itself has an autoland recency that must be satisfied for the feature to be used in a situation that requires it. Situations that require an autoland is any Cat3 or Cat2 ILS where the ceiling is below a certain height (usually stiplated by airline procedures). In order to satisfy the aircraft recency, an autoland can be conducted off any ILS providing the minima is above the height that would otherwise create an autoland requirement.
There are only Cat1 ILSs in Australia, so legally an autoland in a weather situation that requires one cannot be conducted. That is why Australian airports are occasionally closed due to fog - although the aircraft are capable of autolanding in that situation, the ground equipment has not been certified for it.
As
Sopwith Pup mentioned, an autoland can technically be conducted on any runway with an ILS... There was an incident a few years ago where an Ansett A320 flew to Adelaide and encountered fog. The forecast was changed as they got there, indicating the fog would not clear. Without fuel to hold, or fuel to divert, they were forced to conduct an autoland, off the Cat1 ILS, below minima.
Ragardless, your side of the coin is the most correct - most landings are carried out manually.
