Can anyone identify these 1970s singers and the song?

Found this promotional video on youtube with a scene from Australia's Tiki Village in the 1970s:

Not familiar with the song, and the female singer has a great voice - both of them do, actually, and their harmony is nice. Wouldn't mind knowing who they are so that I can track down some more videos or records.

Dig that canoe, I want one to take to Mojave Oasis (a wahine like that would be nice to decorate it with too :D )

I'm sure you saw the credits at the end, looks like Renee Geyer and Dave Allenby are both Australian singers - maybe that will help?

Thanks, Mike.

I missed those credits at the end. Unfortunately, I checked some youtube videos of Renee Geyer and she's more of a pop-singer, (plus she's blonde). She probably did that corny promotional theme that you hear at the end of the video.
