Hi Ian,
This Wikipedia page gives an overview:

I remember visiting this array back in the late 1980s. I am also lucky enough to have also visited the Fleurs array back in 1979 (long before it shut down) as part of an astronomy summer school (I was 17) organised by the Royal Society when it was out near Badgery's Creek.
Best,
Les D
