I'm Aussie and I can't believe this Sun Cable project is being taken seriously by our government.
The longest submarine power cable in the world - the Viking Link - is a mere 756 km long and cost US$2.2bn to build. Sun Cable calls for a 4,200km submarine cable to be built!
I do not expect the construction cost to scale linearly and I shudder to imagine the maintenance difficulties and expenses.
Back in December 2015, Australia's 290km long undersea Basslink cable broke causing the 2016 Tasmanian energy crisis. It took 6 months to get it working again. Basslink eventually went into receivership on 12 November 2021.

Something to ponder.
