Australia's existing high capacity electricity transmission lines. You can see the problem we have, and why we need 10,000 km more. They don't link up. For example if Eastern Australia wants to use Western Australian solar after the sun goes down in the East, it will need to be connected to WA by high transmission lines. (And vice versa for WA in the mornings.) We could build more storage too. Australia plans to do both.
