Australia has a secret weapon in the race for AI compute

As AI compute demand outpaces power grids globally, Australia's vast renewable capacity (solar, wind, geothermal potential) becomes strategic infrastructure. This shifts the compute buildout geography and forces practitioners and cloud providers to reconsider regional deployment and power sourcing.
