Why VCDF’s Expanding Role Matters for Defence

When most people think about Australia’s National Defence Strategy (NDS), they tend to focus on major capability investments, the platforms and weapons systems. However, one of the most significant changes is not about capability itself, but how Defence is reorganising to deliver the strategy.

Over the last decade, Defence capability has largely been developed within Service lines. While this approach produced highly capable platforms, it also introduced challenges. Systems were not always designed to integrate from the outset, gaps emerged between acquisition, sustainment and operational use, and transitions into service were at times uneven. The NDS addresses this by directing the development of an integrated, multi-domain force and shifting away from a collection of platforms towards a connected system. Delivering this vision requires a fundamentally different approach.

This shift changes how Defence defines value. The key capability question is no longer just about platform performance, but how a capability contributes to the integrated force. Interoperability, connectivity and system compatibility are now as important as individual performance. While Service requirements remain important, joint force outcomes have become the critical measure, and resources are being prioritised towards capabilities that deliver the greatest strategic effect.

This has direct implications for Industry. The role of Industry is evolving beyond platform delivery to include supporting integration, enabling effective transition into service, and contributing to sustainment and readiness across the force. Success increasingly depends on the ability to operate within a system, not just deliver a standalone capability.

At the centre of this shift is the Vice Chief of the Defence Force (VCDF). VCDF is responsible for the design of the joint force and for managing the transition to an integrated, multi-domain system while sustaining readiness. This includes sequencing the withdrawal of legacy systems, introducing new capabilities, and aligning workforce and infrastructure. Centralising these functions enables Defence to deliver capability more coherently and efficiently, ensuring that investments are aligned to a joint design and strategic priorities.

The expansion of VCDF’s role is more than an organisational adjustment, it is central to how Defence will realise the intent of the NDS. By elevating joint force integration and aligning capability decisions across the organisation, Defence is moving towards a more coherent, system-based approach. For Defence and Industry alike, this represents a fundamental change. Success will be measured not only by delivering capability, but by how effectively that capability integrates, transitions into service, and contributes to overall readiness. Those who can operate in this more connected, system-focused environment will be best positioned to deliver enduring strategic effect.
