According to federal government, there were 0.63 deaths per 100 million kilometres travelled in 2010, and 0.44 in 2020.

That's a 30% improvement in actual road safety (nationwide) over the last ten years. I'm not sure what the numbers are for Victoria, but I'm sure it's in the same ballpark (VicRoads publishes "per capita" stats, which is a shitty way to measure road safety).
