EV fast-charging network to roll-out in Australia after funding boost 42 sites, each with a minimum of two 350kW fast chargers “That all adds up to about $1 million a site,” adds Mills. “So that initial investment (of $7 million), that gets us going. Great to see more chargers especially modern high power ones. I hope Tesla releases support for these soon. I really don't understand $1million per site though, I can't imagine Tesla is spending this much per supercharger site. I thought they were more like $USD100K for 4-6 chargers.
