We have made a successful start. When the [nuclear] tests are completed, as they soon will be, we shall be in the same position as the United States or Soviet Russia. We shall have made and tested the massive weapons. It will be possible then to discuss on equal terms.

Maralinga is in SW South Australia. Maralinga is Pitjantjatjara Aboriginal dialect for "Field of Thunder". Emu is in NW South Australia. Monte Bello is off the Western Australian shore, near Monkey Mia. Christmas and Malden Is are due south of Hawaii, on either side of the Equator. After the Grapple tests, the British lent the site to the US in 1962 for the Dominic series of 25 explosions.
During the mainland tests many army personnel were deliberately exposed to the blasts just to see what effect radiation had on troops.
Security at the test sites was lax. The testing range boundaries were not properly monitored, allowing people to walk in and out. Any signs were in English, which the local Aboriginal population could not read.
Fallout from the ground blasts led to massive contamination of the Australian interior. The fallout from Maralinga even reached Adelaide and Melbourne. Some places are still heavily radioactive due principally to the presence of the Pu-239 radioisotope.
Compensation is currently being sought in Australian courts.

At the end of the countdown, there was a
blinding electric blue light, of such an
intensity I had not seen before or ever since.
I pressed my hands hard to my eyes, then,
realised my hands were covering my eyes.
This terrific light power, or rays, were actually
passing through the tarpaulin, through the towel,
and through my head and body, for what seemed ten
to twelve seconds, it may have been longer.
After that, the pressure wave, which gave a
feeling such as when one is deep underwater.
This was then followed by a sort of vacuum suction
wave, to give a feeling of one's whole body
billowing out like a balloon.
