First thing to do is define needs beyond rural/ regional. How many kms are regularly driven in one go? Is frequent long distance towing required? Are hard core 4WDing and good clearance necessary?
Unless you have a large amount of coin for buying a Tesla Model X and fitting a towbar, there is no fully electric vehicle yet that can both tow and deliver a longish driving range. The best bet to cover what I would consider rural needs is a Mitsubishi Outlander PHEV, which is a plug in electric hybrid with a full electric range of around 40-45km, and has a petrol motor for range extension. They are rated for towing 1.5 tonnes, and with a decent set of tyres fitted and a suspension lift kit are pretty capable 4WDs as well. I own one of these, and lifetime fuel use is currently sitting at around 3.6l/100km. It probably does 85% of our driving needs on full electric, and fits two kids with associated klatsch, plus four mountain bikes on the back for road trips no drama. I have also towed a 1000l fire trailer with pump up some fairly steep and rugged tracks/ paddocks which it managed with a minimum of fuss
I also own a Gen 1 Nissan Leaf, which is exclusively a town commuter and kid run around car as realistically the range is only about 100km unless you drive it like a grandmother with the heater off. For a second car role though it's absolutely ideal. Quiet, easy to drive, very comfortable with enough boot space, and is super cheap to run and maintain. However there's a whole new swag of four door electric hatchbacks just on the market with much better range. Hyundai has the Ioniq and the Kona, Nissan has a new model Leaf and Tesla has the Model 3. They don't come cheap though, and have obvious limitations once you get off the blacktop.
