Australia’s M&A Renaissance: Why 2026 Is Shaping Up as a Breakout Year for Dealmaking
From Zero to 100: The Sudden Acceleration
Australian public M&A has “gone from zero to 100” in a matter of months, according to global law firm Ashurst, with 2026 shaping up as a breakout year for dealmaking after a challenging 2025. The catalyst came in February when a Macquarie-led consortium agreed to acquire Qube Holdings for A$11.7 billion (US$8.3 billion), the largest Australian M&A transaction since Blackstone’s A$24 billion acquisition of AirTrunk in 2024. Macquarie Asset Management is heading the consortium paying A$5.20 per Qube share, adding a ports and rail operator to its extensive infrastructure portfolio.
The Numbers Behind the Momentum
The data underscores the scale of the revival. Australia recorded US$52 billion of M&A volume across 451 deals in the first half of 2026, up 23 per cent year-on-year, according to Mergermarket data. This ranks among the country’s strongest first-half performances, trailing only 2007, 2011 and 2021. Even excluding the Qube transaction, Australian M&A volume is up 18 per cent so far in 2026 from the same period last year.
However, the full-year picture reveals a more nuanced story. PwC Australia’s M&A Outlook 2026 found Australian deal value reached US$79.5 billion in 2025 (down 8 per cent year-on-year) with volume falling to 1,285 deals. Yet strategic intent remains exceptionally high, with 52 per cent of Australian CEOs planning major acquisitions in the next three years. Of these, 36 per cent are explicitly targeting new capabilities and 27 per cent looking beyond their core sector.
Foreign Capital Floods In
Global investors poured into Australia in 2025, with inbound deals representing 45 per cent of total deal value, up from 30 per cent a year earlier. US, Canadian and Japanese capital led the charge, with standout transactions including Brookfield and GIC’s acquisition of National Storage REIT and CC Capital and OneIM’s scheme for Insignia Financial. Private equity buyouts rose 32 per cent in value to US$30.5 billion across 95 deals, marking renewed momentum after subdued activity following the 2022 peak.
Kushal Chadha, Deals Leader at PwC Australia, captured the sentiment: “The appetite is there and increasingly, it’s appetite for deals that genuinely transform businesses. CEOs aren’t just chasing scale, they’re targeting capabilities and technology that will define how their companies compete in the future”.
Structural Shifts Reshaping the Market
HLB’s Australian M&A Report FY2026 reveals a decisive shift toward quality over quantity. While deal volumes declined to 895 completed transactions in FY2026 from 1,077 in FY2025, the average transaction size jumped to A$162 million, up from A$133 million the previous year. Sectors including technology and materials are attracting premium valuations, while traditional industries face mounting pressure. International buyers continue to pay a premium, with one in three deals involving a global party.
Corrs Chambers Westgarth’s M&A 2026 Outlook identifies six major themes shaping the market: supply chain diversification, increased investment in defence and defence-adjacent sectors, a stronger focus on technology and innovation, a rise in shareholder activism, continued momentum in resources deals, and renewed cross-border investment led by US bidders.
Regulatory Reform Adds Complexity
Australia’s regulatory environment shifted significantly in 2025, with reforms designed to bring greater structure and certainty while demanding more from dealmakers upfront. From January 2026, certain transactions require ACCC notification and clearance before completion—the most significant merger control reform in decades. Foreign investment reviews have also become more nuanced, with deals involving critical infrastructure, minerals, technology or sensitive data facing higher scrutiny.
Despite these complexities, the fundamentals remain compelling. Australia’s reputation as a stable, resource-rich and innovative economy continues to attract long-term investors seeking growth through strategic acquisitions.
