In the UK the hours are reported to the CAA at the annual Permit Renewal, or 3 yearly CofA renewal (depending upon aircraft category).
Total hours, with date valid, are available on G-INFO (and pay the CAA a few hundred quid and you can have it on a CD exportable to Excel, which makes analysis pretty easy).
I'm less sure what the Australians do, but I think it's fairly similar.
So far as I know, the USA does what they call the "Air Taxi Survey" of parts of the fleet, but it's not a whole fleet dataset in the way that certainly exists for the UK.
