Narrator: A cyclone has a sound and it’s not merely the sound of wind
or the odd thump of something hitting the side of the house. 
It’s perhaps the most terrifying sound forty thousand peop-… Australians have ever heard.
The sound of literally millions of sheets of corrugated iron
being scraped across the ground at two hundred miles an hour.
The thump into rather flimsily built fibre board buildings.
And this is where the damage was caused.
I was instantly reminded, and other people have been too
of the similarity to the first shots of atom bomb attacks on the two cities in Japan.
Later in the day we checked out the worst area – the devastated northern suburbs.
Here, houses had literally exploded off their piers, people had been left sitting on bare floorboards
or in the concrete storage sheds under the piers.
Or worse still, were trapped.
One big worry about Cyclone Tracey was that we felt the people down south didn’t know that we were in trouble.
That they were enjoying Christmas quite unaware that we’d been wiped out.
It wasn’t until late afternoon that we managed to get the first story through, and this was by using ship’s radio and contacting Perth for the story to be sent through.
It took almost four hours to establish radio contact with Perth.
[Sound of helicopters]
It was late on Christmas day before the rest of the nation realised the magnitude of the disaster.
The armed services responded immediately on orders from the Natural Disasters Organisation.
Its chief, Major General Stretton, flew to Darwin to take charge.
The air force began a massive air lift, the army flew in engineers and signallers,
and in Sydney the navy readied the sea
The immediate aim was to ensure that Darwin had the basic requirements for survival.
Emergency supplies were taken in by air.
And within two days, more were on the way in ten ships of the Australian navy.
The flag ship Melbourne, the Stuart, Brisbane, Stalwart, Supply, Vendetta, Hobart, Flinders,
and the landing craft Balikpapan and Betano.
The British submarine Odin also set out for Darwin for use as a floating powerhouse.
At the same time, army supplies including medical equipment and food were being prepared for air freighting to Darwin.
Person 1: At this stage, it was help yourself to whatever relief was available
and this was generally done in the most responsible way.
In fact, the large emergency- emergency centres established at places like Casuarina High School were-
were set up by private citizens actually entering the high schools and opening them up so they could become refugee camps
[Child wails]
Person 2: What happened to Darwin on Christmas morning has never happened in Australian before.
Darwin is devastated.
Darwin is destroyed.
Darwin looks like a battlefield,
or ah, Hiroshima.
The people of Darwin have been magnificent through it all.
To come to the aid of Darwin is our greatest national challenge for thirty years.
Narrator: The prime minister Mr Whitlam interrupted his overseas tour to visit Darwin.
Whitlam: My mind inevitably went back to the early nineteen forties when I first saw this city,
not very long after it had been bombed by the Japanese.
And it's heartbreaking to see that all the effort that's been made over an- whole generation
to house people in this city
has been destroyed last Christmas.
Because there's no more people [that] can live in Darwin in present conditions than were able to live there during the war.
And they- the people that live in Darwin now enjoy no better conditions than they did during the war.
Now the great thing I have to say to the people of Darwin is
is that the Australian Government is determined to see that Darwin is rebuilt and restored
and the citizens of Darwin are rehabilitated and returned.
Narrator: Friends and relatives waited for hours at southern airports,
but before leaving on the flight the south, many of the refugees had waited for several days for notification of their departure details.
Some had only the clothes they wore.
Some had left Darwin without being able to say goodbye to fathers and husbands.
But at all the southern airports, as here at Adelaide, everyone tried to give them some comfort.
There was an overwhelming nation-wide urge to help.
Appeals for food and clothing met with such a generous response
that some volunteer organisations had trouble coping with it all
