The past year has marked a pivotal period for Isuzu Australia Limited (IAL) and the wider Australian heavy commercial vehicle sector.

In 2025, Isuzu Trucks achieved its 37th straight year of market leadership*, underpinned by the Australian launch of the all-new MY25 Isuzu truck range. The year also coincided with the introduction of updated Australian Design Rules (ADRs), ushering in higher standards for safety and emissions across the national truck fleet.

“2025 was always forecast to be a significant year for Isuzu in Australia,” commented Director and Chief Operating Officer, Mr Andrew Harbison.

“The introduction of the new ADRs was the trigger for the launch of our all-new MY25 truck range in Australia and for Isuzu, this was a once in a generation model release.

“With our record atop the Australian truck sales race extending back to 1989, there’s a lot of pressure and expectation with every product we bring to market.

“And our brand tagline, ‘Reliability is Everything’ sets a very public standard that we must ensure all our products live up to,” Mr Harbison continued.

“All told, we’ve brought over 200 models from our latest MY25 truck range to market over the past 12 months, spanning the light, medium and heavy-duty weight segments, and to see these trucks represented in another year of sales leadership for Isuzu is a proud moment for IAL and the Isuzu Dealer Network.”

New-generation range drives sustained leadership

More than 200 MY25 variants across light-, medium- and heavy-duty segments were introduced during the year, providing customers with one of the most comprehensive model line-ups ever offered by the brand.

Isuzu secured its 37th consecutive year as Australia’s best-selling truck manufacturer, recording total sales of 12,420 units by the end of 2025.

Despite an overall market contraction, Isuzu increased its total market share to 27.5 per cent, highlighting the strength of customer demand for the new range.

“Once again, over one in four new trucks rolling out of dealerships Australia-wide bore the iconic Isuzu chrome badge in 2025,” enthused IAL Head of Sales Craig White.

“It’s been an absolutely huge year for us, starting with our dealer and customer launch of our new range back in March, which was hotly followed by our grand public unveiling and display at the 2025 Brisbane Truck Show.

“The real test of course was the start of sales in the second half of the year – the interest from across the industry that we had in the lead up to this gave us great confidence and the numbers have borne this out,” Mr White said.

Light-duty strength underpins overall performance

Isuzu Trucks continued to build on its long-standing dominance in the light-duty segment throughout 2025.

Positioned for the next phase of growth

“The team at Isuzu Australia and the Isuzu Dealer Network has another packed year ahead of it as we move into the next phase of growth for the brand,” said Mr Harbison.

“Competition gets tighter and tighter; the operating environment continues to grow in complexity and our customers’ demands evolve with technological and industry requirements.

“We’re thrilled to be bringing new products and services to market, designed to assist and support our customers as partners in their heavy commercial vehicle needs,” he said.

Dealer network continues to set the standard

“The Isuzu Dealer Network must be recognised for their pre-eminence in the Australian truck market,” said Mr White.

“Isuzu’s proud history in Australia stretches back over 50 years and many of our dealers have been a part of the journey since day one.

“All Isuzu truck operators can be assured that their local Isuzu dealer will provide the same peerless customer support and industry nous that has seen Isuzu achieve this remarkable record, as this approach underpins our future success,” he concluded.
