What You'll Learn
Australia's quick reaction to the pandemic
Australia's proactive approach included widespread testing, which helped to identify a high proportion of cases, including mild and asymptomatic ones. This testing strategy, coupled with effective contact tracing, provided a more accurate picture of the virus' severity in the country.
The Australian government also took steps to protect its elderly population, who are more vulnerable to the virus. These measures contributed to flattening the curve and ensuring that the healthcare system was not overwhelmed, allowing for better patient care.
The success of Australia's response can be seen in the low case-to-fatality ratio, which stood at approximately 1.3% at one point during the pandemic. This is in contrast to countries like France, which had a fatality rate of more than 18%.

Widespread testing
By March 2020, about 149,000 people in Australia had been tested for COVID-19, equivalent to about 558 tests per 100,000 people. This testing rate was similar to that of South Korea and far higher than Britain's 117 tests per 100,000 people and the US with just 22 tests per 100,000 people.
The importance of widespread testing is further emphasized by the experience of Germany, which, like Australia, implemented aggressive testing strategies. Germany aimed to 'find every case', and as a result, its lower death rate may represent a truer picture of the crisis. In addition to widespread testing, Germany also implemented meticulous tracing methods right from the outset of the pandemic.
The early and widespread testing strategy in Australia and Germany may have helped these countries to 'flatten the curve' and manage the outbreak effectively, preventing their healthcare systems from becoming overwhelmed. This is in contrast to countries like Spain, France, the US, and the UK, where large case numbers have overwhelmed healthcare resources, making it difficult to provide optimal care for all patients.
While the focus here is on COVID-19, it is worth noting that Australia has also seen success in reducing deaths from other respiratory diseases, such as asthma. The death rate from asthma in Australia has decreased, and it now accounts for less than 0.3% of all deaths, thanks to effective treatments and management strategies.

Age demographics
In Australia, the majority of COVID-19 cases were young people who caught the virus overseas and recovered. This skewed the age demographics of those infected towards younger age groups, contributing to the country's low death rate.
Furthermore, Australia's proactive measures to protect its elderly population have been effective. The country advised its elderly citizens to stay home early in the pandemic and restricted visitations to rest homes, reducing the risk of infection in this vulnerable age group.
Widespread testing in Australia has also played a role in understanding the true number of cases and managing the outbreak. By testing individuals with mild or asymptomatic cases, Australia has been able to identify a higher proportion of infections and implement control measures to flatten the curve effectively.
The low death rate in Australia can also be attributed to the country's ability to manage chronic respiratory diseases, the fourth leading cause of death in the country. The implementation of preventative measures, such as encouraging smoking cessation, has helped reduce deaths from chronic obstructive pulmonary disease (COPD), the main contributor to respiratory-related deaths. Additionally, advancements in asthma treatment, such as the use of preventer puffers, have significantly decreased asthma-related fatalities.

Cigarette smoking
Australia's low death rate can be attributed to various factors, one of which is the country's efforts to reduce tobacco smoking. Tobacco smoking is a significant public health challenge in Australia and is the leading cause of premature death.
Smoking has been linked to increased mortality risk from various causes, including chronic lung disease, lung cancer, coronary heart disease, and cerebrovascular disease. The risk of mortality increases with smoking intensity, and quitting before the age of 45 can significantly reduce these risks. In Australia, up to two-thirds of deaths among current smokers are attributed to smoking.
Large-scale studies have been conducted in Australia to understand the relationship between tobacco smoking and mortality. One such study, the 45 and Up Study, followed over 200,000 individuals aged 45 and above from 2005 to 2017. It found that current smokers had a significantly higher risk of mortality compared to never-smokers, with a two- to four-fold increase in mortality risk for those smoking 1-14 and 25 or more cigarettes per day, respectively. The study also showed that quitting smoking gradually reduced the risk of mortality over time, with no significant difference in risk compared to never-smokers for those who quit before the age of 45.
Australia has made efforts to address the smoking epidemic, with a historical focus on prolonged and heavy smoking, as well as successful long-term cessation programs. As a result, Australia has seen a low current smoking prevalence, with only 13% of adults reporting daily smoking in 2013. This low prevalence of smoking may have contributed to the country's overall low death rate by reducing smoking-related deaths and improving the health of the population.

Low number of intensive care patients
Australia's low death rate during the COVID-19 pandemic can be attributed to several factors, one of which is the low number of intensive care patients.
During the early stages of the pandemic, Australia had a low number of COVID-19 patients requiring intensive care. This was due, in part, to the country's quick response and implementation of preventative measures. Australia, like Singapore and Taiwan, acted swiftly, which was crucial in stamping out early outbreaks and preventing the healthcare system from becoming overwhelmed.
The low number of intensive care patients is also a result of the demographics of those infected. In Australia, most cases were travellers returning from overseas, and the majority of these were young people. The virus is known to be more dangerous to older people, and the young age of many infected individuals likely contributed to the low number of severe cases requiring intensive care.
Furthermore, Australia's widespread testing and contact tracing efforts provided a more accurate picture of the virus' severity. By testing not just those with moderate to severe symptoms, but also those with mild or no symptoms, Australia was able to identify a high proportion of cases. This extensive testing strategy helped to capture the true extent of the outbreak and facilitated more effective management of the pandemic, reducing the strain on intensive care units.
The low number of intensive care patients is significant because it indicates that Australia's healthcare system was not overwhelmed. This allowed for better patient care and likely contributed to the country's low death rate. The availability of intensive care beds and resources is crucial in the treatment of severe COVID-19 cases, and Australia's ability to manage the curve effectively played a vital role in keeping mortality rates low.
