In 2023, the passenger car passenger-kilometres in Australia stood at 292.75 billion. Over the last two years, we've observed a steady yet declining year-on-year growth: 0.68% in 2022 and 0.67% in 2023. This downward trend is also reflected in the 5-year compound annual growth rate (CAGR) from 2013 to 2023, which averages to 0.7%.

Looking ahead, the forecast from 2024 to 2028 suggests a slight reduction in the growth momentum, with the passenger-kilometres expected to increase at a 5-year CAGR of 0.49%. This results in a cumulative growth rate of 2.45% over the period, showing a stable, albeit slower, trajectory.

Future trends to watch for include:

Adoption of new mobility solutions such as ride-sharing and autonomous vehicles.
Impact of sustainable transport policies and electric vehicle uptake on passenger kilometre growth.
Economic factors influencing disposable income and travel behavior.
