Portfolio — 13 May 2026

Deputy Prime Minister and Defence Minister Richard Marles used a House question time appearance on 13 May to frame Australia's expanding defence posture around two reinforcing signals: active multilateral engagement in a contested waterway, and a substantial uplift in domestic defence funding. Marles told the House he joined a meeting of 40 defence ministers to discuss a multinational military mission in the Strait of Hormuz — a chokepoint through which a significant share of global energy trade passes — and confirmed Australia has committed an E-7 Wedgetail aircraft to that mission.

He said further talks with the United Kingdom, France, and other partners are underway about additional Australian contributions, indicating the commitment is not yet settled at its ceiling. The strategic logic Marles offered was explicit: a volatile global environment and the ongoing Middle East conflict raise the risk that adversaries could seek to coerce Australia by disrupting sea lines of communication [TA-260513-house-ee1b85aea947:s174].

That framing positions the Hormuz mission not as a peripheral engagement but as directly relevant to Australian trade exposure and strategic vulnerability. On spending, Marles announced a defence budget increase of $14.5 billion over the forward estimates and $53 billion over the decade, bringing total additional investment to $117 billion over ten years. He drew a direct contrast with the previous coalition government, characterising its planning-decade increase as $10 billion against the current government's trajectory — a twelve-fold comparison he used to anchor the scale of the current commitment.
