Is the upgrade worth it?
Honest answer: only if (a) you have an EV that actually accepts 22kW AC — Tesla Model S/X, Audi e-tron, Renault Zoe — and (b) you do daily long-distance kilometres. A Model 3 or Y caps at 11kW AC regardless of the charger; a 22kW install is wasted on it.
The exception is multi-EV households (two cars, both wanting to charge overnight) and tradespeople with high daily km. For everyone else, single-phase 7.4kW adds 40km of range per hour — enough to fully refill overnight for the average Perth driver.
