The Dish didn’t just come out of nowhere. In fact it, and the whole of CSIRO’s work in radio astronomy, originated in the Sydney suburb of Dover Heights.

CSIRO’s first Dish: the ‘hole-in-the-ground’ telescope at Dover Heights.

There was a wartime radar installation here, where CSIRO radio engineers cut their teeth on the new technology.

The building they used as a base has just been honoured by the National Trust.

After the war our boffins turned their hand to the peaceful uses of radio waves, including exploring the Universe. The rest is history — our history.
