Capital, Capability and Australia’s CGT Question
By Andrew Horton
The recently announced changes to capital gains tax (CGT) in the Federal Budget are framed primarily through the lenses of revenue reform and housing affordability. While these are legitimate national priorities, the broader strategic implications deserve equally serious consideration.
At a moment when advanced technology capability increasingly defines economic strength, industrial resilience and national security, Australia now faces a critical policy question: how can the nation continue to encourage domestic capital to back Australian innovation, enterprise and sovereign capability at scale?
This question matters because the defining strategic competition of the twenty-first century is increasingly shaped not simply by defence spending or industrial output, but by who finances, owns and controls advanced technologies. Artificial intelligence, quantum capability, cybersecurity platforms, sovereign cloud infrastructure, autonomous systems, advanced manufacturing, energy resilience and space technologies now sit at the centre of geopolitical influence and national resilience.
Technology is no longer simply an economic sector.
It is strategic infrastructure.
Capital, correspondingly, is no longer merely financial liquidity.
It is a strategic national enabler.
This is the context in which Australia's evolving CGT framework should now be considered.
The Federal Budget contains several constructive measures. Expanded R&D incentives, venture capital initiatives and targeted innovation reforms signal an increasingly sophisticated understanding within Canberra that advanced technological capability forms part of national power. That shift in thinking is welcome and strategically important.
Modern resilience increasingly depends on trusted digital systems, secure computational infrastructure, sovereign industrial capability and nationally aligned innovation ecosystems.
There is now an opportunity to ensure Australia's capital policy fully complements that ambition.
The proposed CGT reforms - replacing the long-standing 50 per cent discount with indexation arrangements and a minimum 30 per cent effective tax on realised gains will inevitably influence how capital is allocated across the economy. The central strategic consideration is therefore not whether reform occurs, but how reform is calibrated.
Capital responds to incentives.
This is particularly true in advanced technology sectors where risk profiles are materially higher, time horizons are longer and commercial outcomes are less certain.
Dual-use and frontier technologies are rarely built through conservative capital seeking immediate yield. They are typically financed through patient investment willing to absorb significant uncertainty in pursuit of long-term strategic and commercial outcomes. Cybersecurity firms, AI platforms, advanced sensing systems, quantum ventures, sovereign infrastructure providers and space technologies all emerge through capital ecosystems prepared to support innovation before global markets fully validate it.
Australia has historically encouraged this form of productive risk capital through a combination of policy settings including venture frameworks, early-stage investment incentives and the 50 per cent CGT discount.
Those settings have helped support the emergence of globally competitive Australian firms.
The strategic concern now is straightforward.
If domestic investors face broadly similar post-tax outcomes investing in mature global technology incumbents as they do backing earlier-stage Australian enterprises carrying substantially higher risk, capital will naturally gravitate toward safer and more liquid international alternatives.
That outcome would not reflect a failure of patriotism.
It would reflect rational portfolio behaviour.
The implications, however, extend far beyond financial markets.
Nations that consistently finance and scale domestic capability strengthen their economic complexity, industrial resilience and sovereign decision-making capacity. Nations that predominantly consume technologies designed, financed and owned elsewhere gradually become more dependent on external systems during periods of strategic disruption.
This distinction matters more than ever.
Recent global events - from supply chain disruptions and cyber operations to increasing technological fragmentation between major powers demonstrate that resilience increasingly depends on the ability to finance, retain and control critical systems domestically or within trusted alliances.
Capability without capital formation remains difficult to sustain.
The United States understands this dynamic clearly. The CHIPS and Science Act, alongside broader industrial initiatives, explicitly links taxation settings, public investment, research capability and private capital formation to national strategic objectives. Europe, Japan and South Korea are pursuing similar approaches across semiconductors, AI, advanced manufacturing and energy systems.
The common principle is evident: advanced economies increasingly view capital policy as part of strategic policy.
Australia enters this environment with significant strengths.
The nation possesses world-class universities, exceptional engineers, globally respected capability in quantum research and cybersecurity, critical minerals leadership, deep alliance networks and stable institutions. Australia has also already demonstrated an ability to build globally competitive technology firms. Companies such as Atlassian, Canva, WiseTech Global, Cochlear and NEXTDC prove Australian innovation can scale internationally when supported by strong capital ecosystems.
The next phase requires strategic alignment between taxation policy, investment incentives and sovereign capability objectives.
This does not require abandoning reform.
Nor does it require retreating from open markets or foreign investment, both of which remain central strengths of the Australian economy.
Rather, it suggests the value of thoughtful calibration.
A targeted approach that preserves or strengthens incentives for Australians investing in productive Australian enterprises - particularly within strategically significant sectors such as AI, cybersecurity, quantum, advanced manufacturing, defence technology, energy systems and sovereign digital infrastructure would help align tax reform with long-term national capability goals.
Such an approach would continue supporting broad fiscal objectives while recognising that not all forms of capital deployment carry equal strategic value.
Investment in productive sovereign capability generates wider national benefits:
• stronger economic complexity
• deeper industrial capability
• higher-skilled employment
• increased strategic resilience
• enhanced sovereign decision-making capacity
Importantly, domestic capital often plays a unique and important role during the early and scale-up phases of Australian firms. These periods frequently determine where intellectual property resides, where governance structures form and where long-term strategic alignment is established.
Ensuring Australia remains an attractive destination for this form of productive capital therefore carries strategic significance.
This is particularly important because the modern strategic environment increasingly operates in the grey zone between economic competition and national security. Cyber resilience, digital infrastructure, AI systems, communications networks and advanced manufacturing capability all now contribute directly to national preparedness.
Private capital increasingly shapes those capabilities.
That reality requires capital policy to be viewed through a broader national lens.
