Yes, they sure were. You have to use the Samba as a guide only - it's for US-spec German-built VWs. Ours were made in Melbourne.
Australian paint colours are listed at
http://www.clubvw.org.au/colour_identification.htm and as you can see, Aussie colours (Balm/Dulux) were rather different from Germany/US.
I had a Ruby Red Aussie '64 - and it had the grey / white interior. I imagine red upholstry with red paint would be a little hard to take. As far as I can recall, I only saw red upholstry with white paint, although most of the white Aussie VWs had brown upholstry.
The Aussie '67s were 'tarted' up a bit, in order to try to stop the sliding sales (they actually came with white-wall tyres). The door panels were not two-tone, like the earlier cars, but were just one colour.
If you restore your VW to its original colour, note that Dulux made a couple of different shades of Ruby Red. The VW 1.3.303 code (Dulux 4754) is correct for your car. The Dulux 5265 Ruby Red was only used on the VW 1500 Type 3, and is a more browny-red than the sedan Ruby Red (I made that mistake once).
New Grey/white interior panels will look great.
