No, a Trump presidency isn’t business as usual for Australia — he threatens our economy, security and political stability

Tariffs would hit Australian exports and amplify global trade tensions

Australia ships roughly $16 billion worth of goods to the United States each year, ranging from beef and wine to specialised machinery and pharmaceutical products. A blanket 10–20 per cent tariff would immediately erode the competitiveness of those exports in the US market, forcing producers to absorb margin compression or divert volumes to alternative destinations at lower prices.

The last Trump administration's steel and aluminium tariffs provided a preview: Australian negotiators secured a quota-based exemption, but only after months of diplomatic effort and the acceptance of voluntary export restraints. A universal tariff regime leaves no room for product-specific carve-outs, and the administrative burden of seeking exemptions across dozens of tariff lines would overwhelm small and medium-sized exporters.

Retaliation compounds the harm. In 2018 the European Union and China responded with targeted counter-tariffs on American agricultural and industrial goods, redirecting trade flows and raising input costs for US manufacturers. The European Commission has already signalled it is preparing a rapid, calibrated response should Trump implement his new proposals, while Beijing has expanded its own trade remedy toolkit. A spiralling tariff war would depress global demand, disrupt supply chains and reduce the commodity prices that underpin Australia's terms of trade.

Undermining Federal Reserve independence risks a currency war

Trump's intention to remove the Federal Reserve's operational independence — enabling politically directed interest-rate cuts to offset tariff-driven inflation — alarms monetary economists. Saul Eslake, a former chief economist at ANZ Bank, argues that such a move would undermine confidence in the US dollar as the world's primary reserve currency.

Paradoxically, a loss of confidence in the dollar tends to strengthen the Australian dollar as global portfolio managers rebalance toward perceived safe-haven currencies with credible institutional frameworks. A higher Australian dollar makes every export — from iron ore and LNG to education services and tourism — more expensive for foreign buyers, widening the trade deficit and slowing GDP growth.

If other major economies respond by intervening to weaken their own currencies, the world could face a competitive devaluation spiral reminiscent of the 1930s. For a trade-exposed economy such as Australia, a currency war would amplify volatility in export earnings and complicate Reserve Bank of Australia policy decisions.

Geopolitical realignment threatens the Indo-Pacific security architecture

Trump's stated preference for a negotiated settlement in Ukraine that cuts off US military aid and pressures Kyiv to cede territory would represent a fundamental break with the collective-security principles that underpin the ANZUS alliance and the broader rules-based order. Australian governments of both parties have argued that Russian aggression in Europe cannot be separated from strategic competition in the Indo-Pacific; a perceived US retreat in Europe emboldens revisionist powers elsewhere.

The Albanese government has committed significant defence assistance to Ukraine, a position the federal Opposition has criticised as insufficiently robust. A Trump-imposed settlement would place Canberra in a difficult diplomatic position: either align with a Washington that has effectively legitimised territorial conquest, or maintain support for Kyiv and risk friction with its principal ally.

Beyond Europe, Trump's transactional approach to alliances — demanding payment for US troop deployments, questioning mutual-defence commitments — creates uncertainty for defence planning in Canberra. The AUKUS submarine programme, already beset by cost and timeline pressures, relies on sustained US political and industrial commitment. A president who views alliances as protection rackets rather than strategic investments may not prioritise the technology transfers and workforce development that AUKUS requires.

Domestic political contagion: importing US culture-war tactics

The influence of US political trends on Australian discourse is well documented. Commentators aligned with the federal Coalition and sections of the Murdoch and Seven West Media networks have echoed Trump's rhetoric on immigration, climate policy, gender and electoral integrity. A Trump victory would validate the view that polarisation, grievance politics and institutional distrust are winning electoral strategies.

Australian voters have already experienced a measurable increase in political polarisation over the past decade, with trust in democratic institutions declining and social cohesion indicators weakening. The importation of US-style culture-war frames — often detached from Australian policy realities — crowds out debate on housing affordability, productivity growth, climate adaptation and Indigenous recognition.

If Trumpism is rewarded with a second term, the incentive structure for Australian political entrepreneurs shifts further toward conflict and away from compromise. The long-term cost is a degradation of the policy-making capacity needed to address structural challenges such as the energy transition, an ageing population and regional strategic competition.

Modelling the macroeconomic fallout for Australia

UK Treasury modelling cited in the Crikey analysis estimates a 0.6–0.7 per cent reduction in GDP for both the United States and China under a full tariff escalation scenario, with spillovers to Europe concentrated in export-dependent Germany. Australia is not explicitly modelled, but the channels are clear: lower Chinese growth reduces demand for iron ore, coal and gas; a stronger Australian dollar compresses export margins; and heightened uncertainty delays business investment.

The Peterson Institute for International Economics previously estimated that Trump's 2018–19 tariffs cost the average US household $800 per year in higher prices while failing to reduce the bilateral trade deficit with China, which reached record highs. A broader tariff regime would magnify those effects. For Australian exporters, the combination of reduced US market access, weaker Chinese demand and a stronger currency creates a triple squeeze on revenues.

What this means

The 2024 US election is not a distant spectacle for Australian voters, businesses and policymakers. The policy platform Donald Trump has articulated — protectionist, unilateralist and hostile to independent institutions — would produce tangible economic costs for Australian exporters, complicate the Reserve Bank's inflation-targeting framework, weaken the alliance architecture that underpins regional security and embolden the most corrosive elements of domestic political discourse. While institutional constraints may moderate some impulses, the direction of travel is clear. Australian decision-makers in government, business and civil society should be scenario-planning for a more volatile, less rules-based global environment, diversifying export markets, reinforcing regional partnerships and defending the norms that have underwritten three decades of prosperity and stability.
