While that number is an improvement on previous months, it is tiny compared to the 25% to 85% of new cars sold that are all-electric in European nations such as Germany, the Netherlands, Denmark and Norway.
Our team at the National Centre for Social and Economic Modelling, University of Canberra has examined what the Australian Capital Territory (ACT) is doing, and what effect this is having on electric vehicle take-up by price and type of household.
a full exemption from stamp duty on purchase
two years free registration
We used Australian Bureau of Statistics census and household expenditure data as well as microsimulations based on a survey of vehicle preferences to examine behaviour before and after the changes.
We simulated the decision to buy electric based on a total cost of ownership, which included the value of the vehicle as well as operational costs including petrol, service and repair.
The proportion climbs to 11% with zero-interest loan and free registration added.
But even after five years, the proportion of total cars on ACT roads that were electric would be small: just 1.6% with just the stamp duty exemption, and 2.0% with the other measures as well.
This result is much higher than the latest-known proportion of electric vehicles in the ACT, which in 2019 was 0.1%. Nationally, only 23,000 (0.011%) of the 20.1 million vehicles registered are electric.
If there was also a zero-interest loan of $15,000, the proportion would increase to 27%, and with two years free registration as well, to $30%.
As a proportion of the entire car fleet in the ACT, the figures would be 4.1%, 4.8% and 5.3% respectively, depending on those price, loan and registration factors. That would mean much larger demand than at present, but still small enough to mean the infrastructure for maintaining conventional vehicles would be needed for some time.
We found that high income households are far more likely to replace their cars within five years and far more likely to switch electric even without incentives – and that for them, the incentives didn’t make much difference.
