a number of 4 door hardtops were brought into Australia from Canada, main years were from 59 through 69/70,
mostly auto's, the 62 above is typical, the ratio of 4 door hardtops to 4 door sedans was something like 50 to 1, others may know the actual ratio.
A number of these 4 door hardtops were privately imported, ie I nearly bought a 61 Sport Sedan 40 years ago that was assembled in France.
