Nations providing Australia with permanent migrants in 2014-2015 were India and China.
2011 CO2 per capita numbers for Australia is 16.5t
Indians moving here are nearly 10x their per capita emissions back in India (1.7t)
Chinese people moving here more than double their emissions per capita from back in China (7.2t)
It highlights that as those two nations, particularly India have their population enjoy lifestyles closer to the west the less relevant Australia becomes globally.
India living like Australia, which they deserve to just as much as anyone else so there's no fault directed anywhere, multiplies their emissions by an order of magnitude - that takes them to more than twice China who is more than twice the next largest emitter.
Per Capita is just stupid.
When someone moves from india they don't suddenly start finding ways to emit CO2.
A gas drilling operation produces CO2 , lots of things produce CO2. Not necessarily people.
The opposite is also true. What is the biomass per capita in Australia?
