Hey Jon,
I watched it in the late 60s.
Most of it was still showing here in Australia in black and white even though the film was in colour because we didn't have colour television. I quite liked it in black and white, especially those old daleks. It also originally had an "A" rating, meaning at that time it was only suitable for adults which is quite hilarious I think. I'm surprised I was allowed to watch it.

There's an interesting but very long wiki page about Doctor Who in Australia describing what they call "the history and culture" of the show in Australia since January 1965. Some of it is quite funny with decriptions of the film being shipped from city to city after it originally aired. It was very BIG here.
