What DIDS26 Means for Australian Defence Supply Chains

On 2 July 2026, the Federal Government released the 2026 Defence Industry Development Strategy — DIDS26 for short. If you work anywhere near Australian defence industry, you have probably already skimmed the headlines: more self-reliance, more local manufacturing, workforce targets for the primes.

But the part that does not make the headlines is that every one of those ambitions has a freight problem attached to it.

What DIDS26 actually asks for

The strategy sets three outcomes: a stronger and more resilient sovereign defence industrial base, capability delivered through stronger and more diverse international industrial partnerships that reduce supply chain shocks, and a contribution to national productivity by helping Australian defence businesses commercialise and scale.

Underneath that sit the Sovereign Defence Industrial Priorities, the areas that the government has decided Australia must be able to do for itself. They cover maintenance, repair, overhaul and upgrade of ADF aircraft; continuous naval shipbuilding and sustainment; sustainment and enhancement of the combined-arms land system; domestic manufacture of guided weapons, explosive ordnance and munitions; development and integration of autonomous systems; and battlespace awareness and management systems.

If you read that list again as a logistician, it turns into something quite different: outsized aircraft components on AOG timelines, hull blocks and modules needing heavy lift, tracked vehicles needing permits and low loaders, Class 1 dangerous goods with security-cleared handling, and sensitive technology bound by export controls. We have written before about what it takes to transport critical military assets, and none of it gets simpler at scale.

Self-reliance is a logistics problem before it is a manufacturing one

There is a comfortable assumption buried in “made in Australia”,  that if we build it here, the supply chain gets simpler. It usually does not. It gets shorter at one end and more complicated at the other.

A guided weapons facility in regional Australia still needs precision machinery from Europe, raw material from Asia, and a compliant way to move finished product to a magazine or a port. A continuous naval shipbuilding program still depends on modules, plate and componentry arriving in sequence, at the right berth, in the right order,  which is project cargo by any other name. The manufacturing becomes sovereign. The freight becomes more demanding, not less.

DIDS26 is explicit that supply chain vulnerability is a core risk to national defence. Which means the question your program office starts asking is no longer just “can you deliver it”,  it is “what happens when the primary route closes”.

Four questions worth asking your freight forwarder 

• Can you actually handle this class of cargo? Explosive ordnance, export-controlled technology and classified componentry are not add-ons to a standard forwarding service. Ask what has been moved, not what could be.
• Who has visibility, and how? Chain-of-custody expectations in defence are different. Encrypted tracking, controlled access and a documented handover trail should be standard, not an upgrade.
• What is the second route? If the plan depends on one port, one carrier or one air corridor, it is not a plan, it is a preference.
• Who is personally accountable? On defence programs, a single point of contact who knows the whole movement beats a ticketing system every time.

The partnership point

One of the more interesting shifts in DIDS26 is the emphasis on genuine partnership over transactional relationships. That is a fair signal for how the defence industry should work with its own suppliers, too.

Logistics providers brought in at bid stage rather than after contract award consistently deliver better outcomes, because route feasibility, permit lead times and port capability shape the schedule you are committing to. Discovering in month nine that the only crane capable of lifting your module is booked out for a quarter is an expensive way to learn that lesson.

What to watch over the next 12 months

DIDS26 sits within a biennial cycle alongside the 2026 National Defence Strategy and the Integrated Investment Program, with further detail still to come through the Defence Policy for Industry Engagement and Partnership. The Government’s announcement framed industry policy as security policy, and the practical implication for anyone in the supply chain is that requirements will keep firming up rather than settling. Build schedules on the assumption the compliance bar rises.

Where TGI Cargo fits in

We have spent more than 30 years moving cargo that does not fit the standard system, including critical assets under our defence logistics solutions. Our teams sit in Brisbane and Canberra, close to both industry and the decision-makers, and our defence work is backed by military-encrypted GPS tracking, dedicated vessels where required, and a single point of contact who owns the movement end to end. It is a large part of why clients choose TGI.
