This is a bulk water tanker. Its job is to shuttle water from a reticulated urban supply to a staging area somewhere else. It's not the sort of vehicle that ends up on an actual fireground. That said, don't expect to see electric bushfire trucks anytime soon. The first reason is that 30 year old trucks often go to auction with less than 40,000km on the odometer. They aren't utilised enough for electrification to make any sense from an environmental or cost perspective. The second is that no EV truck manufacturer builds vehicles with batteries designed to withstand direct flame attack. Commercial off the shelf trucks are modified with spray bars, insulation covering electrical cabling, fuel and air lines etc to greatly improve their survivability if impacted by fire, but that isn't an option for any EV truck currently in existence. The third of course is the logistical nightmare of having to recharge vehicles. It's easy to quickly refuel 30 diesel trucks from a fuel tanker (or even from drums), but much harder to charge 30 BEV trucks without mains power in the middle of nowhere.
