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.
