We don't use petrol engines for trucks because diesel is more efficient and has better power delivery characteristics. We choose the power plant that suits the needs.
At this stage nobody is proposing battery-electric power for very heavy haulage, although Tesla is working on battery power for smaller transport, like standard semis. There are also lots of designs now around to do battery swaps in just a few minutes. At the risk of being perceived as Tesla's mouthpiece, their model S and later can now do a complete battery swap at a dedicated station in less than 3 minutes, which is quicker than a petrol car can fuel up at 15 liters/minute (the standard pump flow rate).
At present there is no question that EVs are a poor option at the moment in Australia, but there is equally little question that this will change.
