Which parts of the world are the most underpopulated?

Question

Would 5 billion people in Africa sound nice? How about 100 million in Australia and 200 million in Canada? Are there any places that ought experience a five-fold increase in population? Please answer these questions if you like humanity.

Update:

The eastern half of Australia has the largest aquifer in the world.

I think 100 million liberals would be great in antartica

Toni Parr · Answer

At 100 million the Australian environment would collapse within decades due to an exhausted water supply.

Edit - The basin is already showing signs of declines due to over use. The water is not being replaced as quickly as it is being taken out. Many bore holes are no longer viable due to water levels dropping and lack of pressure.

Accelerating the population would also accelerate the decline.
