What Classics Did You See Last Week? (5 June to 11 June 2017

Yes. I would estimate less than 1% of pre-1970 Australian television survives (although I admit that is counting daytime talk shows and such). The 1970s shows survival rate isn't much better, with even prime-time drama often being lost.

I know that ABC's live TV plays of the 1950s/1960s (nearly all of which were kinescoped or later video-taped) were mostly destroyed in the 1970s.
