This old video featuring The Seekers and the 1966 hit, 'California Dreamin', is apparently set on a Qantas V jet, the airline's commercial name for its B707 fleet.

Note the 'wall paper' style artwork on the side walls. Ansett and TAA used to have similar customised artwork on their 727 and DC9 interiors; Canberra features included attractions such as the War Memorial amnd the Academy of Science.
