W & G in Australia also released the Marvellettes "Please Mr Postman" and, amazingly, Bunny Paul's "I'm Hooked".
But it all started in Australia with Bob Kayli on London (that's if you count Bob Kayli as a Motown record) and then Barrett Strong "Money" and the Miracles "Shop Around" both on London.
Then there was the Spinners "That's What Girls ... " on Aussie Astor in 1961 (again that's if you count the Spinners as a Motown record) and then, as you say, HMV and Stateside and finally Australian Tamla Motown.
Also, interestingly, there was actually an Australian Tamla Motown Appreciation Society, based in Melbourne, whom I understand were associated with Dave Godin and the UK counterpart.
