Perth’s public transport network took a significant step towards full electrification this week with the completion of major upgrades at the Karrinyup bus depot, now equipped with 112 new electric vehicle (EV) charging points. The upgrade, finalised on July 18, 2026, marks a key milestone in a joint $250 million initiative by the Albanese and Cook Labor Governments aimed at phasing out diesel buses and delivering comprehensive EV charging infrastructure across Perth.
The Karrinyup depot, located in Perth’s northern suburbs, has been fitted with 56 dual electric bus chargers, making it Perth’s largest EV bus depot to date. This extensive upgrade is designed to support more than 100 electric buses, contributing to a cleaner, quieter, and more sustainable public transport system for Western Australia.
Federal Climate Change and Energy Assistant Minister Josh Wilson highlighted the broader benefits, stating, “The Albanese Government’s $125 million investment in electric charging infrastructure across Perth’s bus depots is helping deliver a cleaner, quieter and more reliable public transport network, including at Karrinyup, where infrastructure now supports more than 100 electric buses.”
This investment underscores a national push towards decarbonising transport, with electric buses offering tangible environmental advantages.
“Electric buses improve local air quality, reduce transport emissions and provide real benefits for the communities they serve, while supporting Australia’s progress towards net zero.”
Accelerating Western Australia’s Electric Fleet Transition
The $250 million program is jointly funded by the federal and state governments, with the federal share amounting to $125 million. It has already seen the delivery of an initial 130 electric buses into the Transperth network. The Karrinyup depot is the third site to be completed under this initiative, following upgrades at Elizabeth Quay Bus Station and the Malaga Bus Depot.
Works are currently underway to transform other key depots, including Bayswater and Jandakot North, which are slated to support up to 130 and 82 electric buses respectively. Further planning is also in progress for upgrades at Welshpool, Joondalup, and Claisebrook depots, indicating a sustained commitment to expanding the state’s electric bus fleet.
Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King emphasised the significance of the Karrinyup project, noting, “Karrinyup will be one of the first EV bus depots to operate outside of the Perth CBD, and this retrofit will support cleaner, zero-emission buses throughout Perth’s suburbs.”
The Broader Shift to Electric Transport
The electrification of public transport fleets, such as Transperth’s, is a critical component of Australia’s journey towards reducing overall carbon emissions. While much attention often focuses on private passenger vehicles, the transition of heavy vehicle fleets, including buses, offers substantial environmental and economic benefits due to their high mileage and fuel consumption.
This large-scale infrastructure deployment highlights the complexities and significant investment required to support high-power charging for commercial vehicles. Unlike residential EV charging, which can often be managed with slower overnight charging, bus depots require robust fast-charging capabilities to ensure fleets are ready for daily operations. For individual EV owners considering how to best power their vehicles, understanding different charging speeds and infrastructure is key. For those looking to maximise their home charging efficiency, especially with solar, guides like Optimise EV Charging with Solar This Winter 2026: Max Savings Guide offer valuable insights.
The project at Karrinyup also involved a reconstruction of the depot yard, including additional parking for drivers, new line marking, and refurbished driver and staff facilities. This holistic approach ensures that the transition to electric buses is supported by modern, efficient operational infrastructure.
Impact on Local Manufacturing and Jobs
Beyond environmental gains, the Cook Labor Government views local electric bus manufacturing as a cornerstone of its “Made in WA” plan. This initiative aims to diversify the state’s economy and foster local job growth, establishing Western Australia as a leader in sustainable transport solutions.
The ongoing commitment to electrifying public transport, evidenced by the Karrinyup upgrade and future depot plans, signals a long-term shift that will reshape urban mobility and contribute to Australia’s net-zero ambitions. As more electric vehicles, both private and public, enter the market, the demand for robust and accessible charging infrastructure will continue to grow, making such investments crucial for future sustainability. For strata and apartment residents, the challenges and solutions for installing EV charging can be quite distinct from a large depot, as explored in EV Charging for Australian Apartments & Strata in 2026: Solutions & Costs from $1,000.
