Much of China and India are in temperate latitudes with fertile crop lands. Their cultures have always encouraged large families while neither their economic system or their medical infrastructure are conducive to the mass distribution of birth control methods but China is very much ahead on India in this, with both the government and their society embracing and promoting one-child-per-family concept.
Much of Australia is arid desert or near desert where the land isn't able to support a human population.
length of being inhabited china india 5,000-7,000 years australia maybe 700-1300.

Cause they are hella freaky..
because there are loads of chinese and indians
austrailia is populated by immigrants and they have very strong immigration laws consequently the population is very low same with canada

Australia is only populated on the coastline areas because the entire country is desert and ppulated by Aboriginals.
The desert limits them....Look at the Sahara's population...
Lots of food - they have a lot of fertile earth and food
Oldest countries - They are 2 of the oldest countries on earth. Man came from the middle east and populated egypt, india and china first so they have more generations than other counries.
Less wars - Other then internal conflicts and civil wars and that little mongol invasion that killed 30 million, china and india really haven't had wars with other countries. No wars means less people dying.
