While it can be quite a poltically charged topic of debate, I'm generally a fan of the 'Big Australia' concept and it's population growth...
Population growth foundational to Australia's economic success story and powered largely by skilled migration – a powerful engine for prosperity, dynamism, and long-term strength of the place. It's one of the key reasons Australia has punched above its weight globally....
Like everything there's pro's and cons!
Pros.....
Larger economy, more innovation, and productivity.
Stronger tax base for services and infrastructure.
Greater geopolitical weight in the Indo-Pacific.
Fills labour shortages and sustains growth.
Cons......
Strains housing, infrastructure, and urban congestion.
Environmental pressures (water, emissions, biodiversity).
Risk to per capita living standards if supply doesn't keep up.
Public backlash over rapid change and affordability.
Everyone is doing this in some form or another, however Australia gets it right better than most in my opinion!
