It changes depending on the context. The Australian boom didn't last quite as long as the US boom. The Baby Boom didn't hit every developed country, since some weren't as involved in WWII (or at all in some cases, such as Switzerland, Sweden). But yeah. Tony's pretty much at the extreme end of what could be considered the boom, but his birth & childhood in NZ pretty much rules him out of the Australian Baby Boom.
Certainly he's too old to have been into Transformers as a kid, which is I guess the relevent aspect here.
