The armies’ comparison by the size

The army size directly depends on the country’s population and its mobilization potential. In the table below there is the information about human resources, mobilization potential and armed forces size of Mexico and Australia in 2025.

ТThus, Mexico leaves behind Australia by the number of soldiers in the service and by its mobilization potential.

Let’s note that the above mentioned data show only the quantitative characteristics without taking into account the professional level of military personnel and the quality (basic skills, physical condition, etc.) of the mobilized and conscripts.

It’s more difficult to estimate such parameters as motivation, combat spirit and soldier’s steadfastness, the ability and wish to perform their duties up to the end.

The comparison of military budgets    up↑

The military financing greatly depends on the country’s wealth – the stronger the economy is developed, the more finance can be allocated for the military expenses. As for the economy size, Mexico with its GDP of 3317 billion dollars (which was calculated by purchasing power parity) surpasses Australia with its GDP of 1898 billion dollars in times.

Mexico and Australia send 0,23 % and 2,93 % of GDP to the military expenses, respectively. As a result, the military budget of Mexico is 7.6 billion dollars and of Australia is 55.7 billion dollars.

Hence, the military expenses of Australia are times higher than in Mexico.

The comparison of armament     up↑

In the table below there is the information about some types of armament which are at the disposal of Mexico and Australia (we account the total amount of weapons in 2025, without considering modifications, the year of release and departmental affiliation):

Mexico and Australia have naval forces. The total displacement of the military fleet of Mexico is 23 thousand tons, Australia - 123,4 thousand tons.

The comparison by the combat power index    up↑

While contrasting the armed forces of Mexico and Australia one can orient on military strength ranking from GlobalFirepower (GFP). The GFP experts have analyzed more than 60 different factors which affect the defense ability of different countries and the effectiveness of their armed forces. As a result, they have calculated the combat power index. The lower it is, the stronger in the military sense the country is.

As of 2024, the countries under consideration take the following positions in GlobalFirepower rating:

● Mexico - 32 position in the world according to the combat power index 0.5965;

● Australia - 18 position in the world according to the combat power index 0.3298;

Thus, according to the GlobalFirepower, the more combat-ready are the armed forces of Australia.
