Volume

Overtime, arrivals have generally increased, and Australia has become a more populator destination within these countries.
Some countries where Australia is a more popular destination generated more arrivals than the populous countries e.g. New Zealand in comparison to China.

Wealth

In general, Australia has becomes a more popular desination as economies and incomes have grown.
This highlights several countries with the potential to become major sources of arrivals if economic development and incomes continue to rise.

Population

Countries in the top left quadrant may have the largest potential for future growth. Especially those with relatively smaller GDP’s per capita (smaller bubble size).
Some countries to the left of the chart appear under-represented in arrivals given their relatively high wealth e.g Saudi Arabia, Brazil and Mexico.

Distance

Overtime, distance has become less of a factor, as poorer countries have become more wealthy (with less spread across the x-axis).
In general, Australia is a less popular destination in countries that are further away. However, the bubbles get larger from left to right, indicating again that the barrier and cost of distance can be overcome by wealth and historic ties.
