So, as most of you know Martin/Molloy was finally inducted into the NFSA's collection a few weeks ago. After I learnt about this I decided to have a bit of a look at what was in their archive. It seems that the tapes Tony Martin sent in are compilations of each week's lot of episodes. You can filter out all the compilation episodes to reveal a few full episodes sitting in their archive:

A lot of these episodes aren't around anywhere else so I decided to look into how one could go about obtaining them. After looking into it a bit, it seems to be the case that general members of the public can't order copies of things from the NFSA

Anyway, hope somebody finds this info useful at some point. In the meantime, you can check out the snippets of Martin/Molloy that the NFSA has made public their website here:
