The article speculates that the increase in pedestrian deaths is due to e-bikes and e-scooters. I’m not convinced that this speculation is based on actual data though.

After a bit of digging I found a government resource on road fatalities:
https://catalogue.data.infrastructure.gov.au/dataset/australian-road-deaths-database

This data does not seem to track the vehicle that caused the road fatality, unless that vehicle is a bus, heavy-rigid truck, or articulated truck. So there would be no way to determine from the data available whether the increase in fatalities is due to e-bikes and e-scooters.
