Thanks guys, cool to hear the info though. Its actually thanks to you Zoofan15 that we know that Taronga's Sumatran tiger story did not begin with Meta & Nico's Jan 1979 arrival from Rotterdam, was the beginning of a lineage that now stretches 45+ years, but the zoo had Sumatran tigers for 27 and a bit years prior to them with Cija & Max.
Heres some other videos found on youtube of the zoo back in the day
(the first one just below, was made clearly made for a children audience as the video intro itself states, but still very interesting from historical p.o.v)
The latter video just above from 1978, must admit already posted on here a while back (and just a heads up: the latter part of video is the family who filmed own family lives footage but the main part of is Taronga),it's fascinating seeing the lions and one of the tigers in the old pits and other cool animals like poor lonely Chori 0.1 the African elephant in her not-good enclosure, but historically interesting.
This is a much more recent one from about 11 or 12 years ago:
