Try Wollumboola base, I think you'll have more luck.

Google cannot find this or anything similar.
Despite that I am sure it exists.

So can any other old fart remember back to the original TV series around
1960?

Wonkypedia talks about a series in the '80s but this is far too late for
the one I'm thinking of.
