Land area: Australia is bigger than Saudi Arabia
Australia is approximately 7,741,220 sq km, while Saudi Arabia is approximately 2,149,690 sq km. This makes Australia around 260% larger than Saudi Arabia, or 3.6 times bigger in land area.
To put it another way, Saudi Arabia is only around 27.77% the size of Australia. In terms of sheer land mass, Australia dwarfs Saudi Arabia.
The difference in size is also reflected in the length of their coastlines. Australia boasts a coastline of 25,760 km, whereas Saudi Arabia's coastline is 2,640 km.
Despite the vast difference in land area, Saudi Arabia's population is significantly larger than Australia's. Saudi Arabia is home to approximately 35.4 million people, compared to Australia's population of around 26.1 million.

Population: Saudi Arabia has more people
Despite being much larger in terms of area, Australia's population pales in comparison to Saudi Arabia's. Australia spans approximately 7,741,220 sq km, whereas Saudi Arabia is approximately 2,149,690 sq km, making Australia over 260% larger than Saudi Arabia. However, the population of Saudi Arabia is approximately 35.4 million people, whereas Australia's population is around 26.1 million people. This means there are around 9.2 million more people living in Saudi Arabia.
The vast difference in population sizes between the two countries can be attributed to various factors. One significant factor is the geographical distribution of inhabitable land. While Australia is much larger than Saudi Arabia in terms of area, much of Australia is desert or otherwise uninhabitable, limiting the number of areas suitable for human settlement.
Another factor is historical and cultural. Saudi Arabia has a long history of human habitation, with many ancient civilizations and empires flourishing in the region. The country is also located in a region with a high overall population density, including neighbouring countries like Egypt and Iran. This has likely contributed to Saudi Arabia's higher population over time.
Additionally, Saudi Arabia has experienced significant population growth in recent decades due to various factors. The country's oil wealth has attracted many foreign workers, and the country has also invested heavily in infrastructure and development, making it an attractive destination for migrants from neighbouring countries.
In contrast, Australia has strict immigration policies that may contribute to its lower population growth rate. Australia's geographic isolation, far from other highly populated regions, may also play a role in its lower overall population.

Life expectancy: Aussies live longer on average
Australia is approximately 7,741,220 sq km, while Saudi Arabia is approximately 2,149,690 sq km, making Australia about 260% larger than Saudi Arabia. However, Saudi Arabia has a larger population, with around 35.4 million people compared to Australia's 26.1 million.
When it comes to life expectancy, there is a notable difference between the two countries. Australia has a higher life expectancy at birth, with Australians expecting to live, on average, 0.184 years longer than Saudis between 1980 and 2006/2007. The exact life expectancy figures for Saudi Arabia are hard to find, but according to one source, between 1980 and 2014, life expectancy at birth increased by 11.3 years, and the country aims to increase life expectancy at birth by 6 years between 2016 and 2030, from 74 years to 80 years. This would mean an average gain of 0.43 years per year.
The higher life expectancy in Australia can be attributed to various factors, including socioeconomic development, healthcare, and public health policies. Australia's cumulative efforts in improving its population's health have resulted in longer life expectancies for its citizens. Additionally, Australia's success in controlling infectious and parasitic diseases and reducing deaths in infancy and childhood have also contributed to its higher life expectancy.
On the other hand, Saudi Arabia is making remarkable improvements in health and human development. The country has a "very high human development index", indicating positive gains in life expectancy in the coming years. The Saudi Arabian government has set ambitious targets to increase life expectancy, and their vision for 2030 includes plans to address demographic and behavioural factors, inequalities, healthcare delivery, public health provisions, health-related policies, and advancements in science and technology.
In summary, while Australia is significantly larger than Saudi Arabia in terms of land mass, Saudi Arabia has a higher population. Aussies do live longer on average, but Saudi Arabia is making strides to increase life expectancy, with ambitious targets set for 2030. The two countries differ in their current life expectancies and the factors influencing them, but both are committed to improving the health and longevity of their citizens.

Obesity: More Saudis are obese
Australia is approximately 7,741,220 sq km, while Saudi Arabia is approximately 2,149,690 sq km, making Australia around 260% larger than Saudi Arabia. However, Saudi Arabia has a larger population, with around 9.2 million more people living there than in Australia.
Obesity is a significant health issue in Saudi Arabia, with a higher prevalence of obesity among its population than in Australia. A recent study found that obesity was prevalent in 23% of the Saudi population, with slightly higher rates among women (24.2%) than men (23.1%). Obese individuals in Saudi Arabia tend to consume more soft drinks and fast food, with a particular fondness for Arabic shawarma, burgers, sausage, and pizza.
Sociodemographic factors play a role in obesity rates, with gender, nationality, social status, educational level, occupation, and monthly income all having a significant impact. Interestingly, obesity was more common among housewives, with a rate of 24.9% compared to 17.5% for other Saudi nationals. Income also influenced obesity rates, with 44.5% of people earning more than SR 20,000 per month being overweight, while 39.5% of those earning less than SR 5,000 per month maintained a normal weight.
The high obesity rates in Saudi Arabia have prompted calls for focused intervention strategies and preventive measures. Experts recommend making obesity prevention through active lifestyles and healthy diets a national public health priority. Awareness campaigns in schools and colleges could help educate the new generation about the consequences of obesity and the importance of maintaining a healthy weight, thereby reducing their risk of developing obesity-related health issues later in life.
The Saudi government and research organizations are urged to prioritize ongoing surveillance of overweight and obesity rates in the country, with a particular focus on identifying effective prevention methods. The book "Overweight and Obesity in Saudi Arabia: Consequences and Solutions" offers valuable insights into the current prevalence of obesity, its risk factors, and the economic and health burdens associated with this chronic condition.

Coastline: Australia has a longer coastline
Australia has a significantly longer coastline than Saudi Arabia. Australia's coastline stretches for 25,760 km, while Saudi Arabia's is only 2,640 km long. This is a difference of 23,120 km, which is a considerable distance.
The vast difference in the length of their coastlines can be attributed to several factors, including each country's geographic characteristics and territorial boundaries. Australia, as the world's sixth-largest country by total area, encompassing approximately 7,741,220 square kilometres, has a much larger landmass than Saudi Arabia.
Saudi Arabia, officially known as the Kingdom of Saudi Arabia, is the largest Arab state in Western Asia by land area and the second-largest in the Arab world after Algeria. It covers an area of approximately 2,149,690 square kilometres, making it the 12th-largest country in the world.
In contrast, Australia's territory includes not only the mainland Australian continent but also the island of Tasmania and numerous smaller islands. This fragmented geography contributes to a more extensive coastline compared to Saudi Arabia's more compact landmass.
The shape and configuration of a country's borders can also influence the length of its coastline. Australia's coastline features numerous indentations, peninsulas, and islands, resulting in a more intricate and extended coastline compared to Saudi Arabia's relatively smoother contours.
