I have been sent this cutting from a Perth newspaper advertising this programme - dated 16 March 1977. The text reads: "Yorkie introduces:

"ABBA - Sweden to Perth
Join Agnetha, Björn, Benny and Frida as Yorkie introduces ABBA - Sweden to Perth for the first time on TV tonight on Channel 9. See exclusive interviews. See their sneak arrival in Perth. Hear the great ABBA hits. Discover for yourself what has made them superstars. Tonight on 9."

The cutting came from the newspaper The West Australian, (p.10) widely known as The West. It is the only locally-edited daily newspaper published in Perth, Western Australia.  It's more than likely that this programme does not contain any unique footage but that it instead is made up of various news rushes footage filmed by Channel 9 cameramen and interspersed with perhaps interviews (with the publi perhaps?) or PROMO videos.

ABBA left Perth on 13 March giving the programme-makers just three days maximum to put the programme together. The footage was probably made up of all or some of the following:

9 Mar - News Rushes: Arrival in Perth
9 Mar - News Rushes: Perth Boat Trip
9 or 10 Mar - News Rushes - Perth (en route to sound check)
10-12 Mar - News Rushes: Meeting Alice Cooper
13 Mar - Nine News - Departing Perth

The programme most likely lasted for 1 hour according to the newspaper cutting.
