1919: Spanish flu pandemic reaches Australia

In a snapshot
At the end of the First World War, in 1918 and 1919, the ‘Spanish flu’ pandemic killed more than 30 million people worldwide.
As an island, Australia was able to quarantine people when they arrived by sea. All the same, about 15,000 Australians died of the flu in 1919.

What was Spanish flu?
Spanish flu was a type of influenza. It did not really come from Spain. People thought it did because it was first widely reported there. But that was because Spain was neutral in the First World War, and there was no wartime censorship on Spanish newspapers.
Scientists do not know where Spanish flu came from. But like all types of influenza, it was very contagious and the virus which caused it could mutate quickly.
The disease spread quickly in Europe because of the war. Soldiers were crowded and lived in poor conditions. Military hospitals became virus hotspots. Civilians had also been badly affected by the war.
Widespread international travel by sea helped spread the flu to every continent, especially as soldiers returned from the war in Europe. One estimate is that about 500 million people — a third of the world’s population at the time — caught Spanish flu.

How dangerous was Spanish flu?
We will never know how many people died of Spanish flu. Estimates today generally range between 30 and 50 million. We do not have good data for many parts of the world. It is also complicated because many of those who had the flu and died were wounded or had other diseases, or were suffering from malnutrition. Death rates were highest in parts of Asia and Africa.
Outside Australia there were three main waves of Spanish flu. The first wave in early 1918 was like a normal flu. But then the virus seemed to mutate and become more deadly. Most people died in the second and third waves in late 1918 and 1919.
Usually flu is most dangerous for very young children and old people. But the second and third waves of Spanish flu killed large numbers of healthy young adults. Many people died because the flu (caused by a virus) developed into bacterial pneumonia.
When did Spanish flu arrive in Australia?
Australia was lucky because it is an island. From October 1918 the Australian Quarantine Service checked all ships arriving in Australia. People with suspected flu had to stay in quarantine.
Despite these precautions, the flu did spread into the community. The first case appeared in Melbourne in early January 1919, and the disease soon spread to New South Wales and South Australia. However, it did not reach Western Australia until June 1919.
Some states closed their borders to try and stop the spread. In New South Wales the government quickly closed schools, theatres and bars. Sporting events and church services were banned. People had to wear face masks on public transport, in the street and in public buildings. These restrictions were relaxed at the end of February, but were reimposed after a spike of infections in March.

‘Australia must now face the fact that the scourge which has taken so heavy a toll from the rest of the world has invaded her own frontiers.’
Sydney Morning Herald, 28 January 1919

When was a vaccine introduced?
Spanish flu was caused by a virus. At the time scientists knew very little about viruses, which were too small to be seen with microscopes.
However, scientists did know about bacteria, and many who died from Spanish flu were killed by a secondary bacterial infection, which caused pneumonia.
In 1918 the Commonwealth Serum Laboratories in Melbourne developed a vaccine for pneumonic influenza. It produced three million doses for Australian soldiers and civilians. The vaccine did not stop people from catching Spanish flu, but it did make them much less likely to die.
‘A danger greater than war faces the State of New South Wales and threatens the lives of all ... Follow the advice given and the fight can be won ...
EVERYONE SHALL WEAR A MASK
Those who are not doing so are not showing their independence — they are only showing their indifference for the lives of others — for the lives of the women and helpless little children who cannot help themselves.’
Proclamation of NSW Government regulations, Sydney Morning Herald, 2 February 1919

How bad was Spanish flu in Australia?
By the end of 1919 the pandemic was over. Probably between a quarter and a third of Australians caught the flu. Nearly 15,000 died. In Sydney alone 3,500 died. Many more men died than women, especially among young adults.
One badly affected group were those in Aboriginal communities. Nearly a third of those who died from Spanish flu in Queensland were Aboriginal.
Many Aboriginal people lived on missions. They were often in poor health before the pandemic and they did not have access to good medical facilities. On some missions around 15 per cent of those who caught Spanish flu died. This was a much higher rate than among white Australians: about 1.2 per cent of those who caught the flu in Sydney died from it.
But overall quarantine had saved Australia from the worst. Australia got off very lightly compared with many parts of the world.
