Canberra pushes back on Trump-era tariffs, but the slavery-era clause in Australian law does the work itself
Australia's trade minister, Don Farrell, told reporters on 9 June 2026 that a fresh round of United States tariffs targeting Australian exporters was "not linked" to Australia's Modern Slavery Act, the 2018 statute that requires large companies to report on supply-chain risks. The denial, reported by SBS News, came as US officials have privately pressed Canberra to weaken provisions in the Act that American firms say expose them to liability for downstream labour practices in Asia. Canberra's position is that the two policy tracks run on separate rails. The trade data, and the timing, suggest the rails are closer to parallel than the minister is letting on.
The dispute is the first concrete collision of the second Trump administration with a mid-sized, US-aligned economy over labour-rights regulation, and it is being watched closely in Wellington, Tokyo and Seoul. The structure of the fight is familiar: Washington extracts concessions from allies under the cover of a tariff threat, while the targeted country insists the two questions are unrelated. Whether they actually are is the only question that matters for Australian exporters.
What Farrell said, and what the US is signalling
Speaking to SBS on 9 June 2026, Farrell framed the new tariff measures as part of a broader American push to reshore manufacturing and reduce dependency on Chinese inputs. The slavery-law provisions, he said, were "not on the table." The US Trade Representative's office has not published the legal text underpinning the new measures, but reporting from the Sydney Morning Herald and the Australian Financial Review in recent months has pointed to supply-chain due-diligence requirements — including clauses in Canada's and Germany's forced-labour import bans — as a friction point in trade-staff talks.
In plain terms, the US argument is that overlapping national rules on supply-chain disclosure create a compliance thicket that functions as a non-tariff barrier. The Australian counter is that the Modern Slavery Act is a transparency regime, not a trade instrument: it does not block imports, and it does not impose duties. Whether that distinction survives a US trade-action probe is the open question.
The structural frame: labour law as the new tariff battlefield
The deeper story is that labour-rights and supply-chain statutes have moved from the margin to the centre of trade diplomacy. Between 2022 and 2025, the EU's Corporate Sustainability Due Diligence Directive, the US Uyghur Forced Labour Prevention Act, and a wave of national modern-slavery laws turned corporate reporting on supply-chain risk into a routine compliance burden. Industry groups in Washington now treat those statutes as a de facto trade issue, and they have the ear of an administration that reads regulation of any kind as friction.
Australia is an interesting test case because its Modern Slavery Act is, by global comparison, a light-touch instrument. It requires reporting, not remediation. Penalties for non-compliance are limited. The point of the statute, as its original drafters argued, is to make corporate supply chains legible to investors and civil society — to let sunlight do the work. That is precisely the design feature that irritates trade hawks in Washington: a law that does not block goods can still shape where they are sourced from, and that effect is hard to measure and harder to litigate.
Counterpoint: the two-track theory has real evidence behind it
Farrell's insistence that the two files are unconnected is not a non-starter. The new tariff measures sit inside a 2026 American push that has hit a long list of jurisdictions, including several with no modern-slavery statute at all. The shape of the package — broad-based, with sectoral carve-outs for critical minerals and pharmaceuticals — is consistent with a reshoring logic, not a labour-law one. American unions, the domestic constituency most invested in the slavery-law fight, have been notably quiet on the Australia file, which suggests the link is weaker than some Australian commentators have assumed.
The honest read is that both things are partly true. The tariffs are primarily a reshoring instrument; the slavery-law provisions are a secondary irritant that the US may use as leverage in a side negotiation. That is how trade politics usually works: smaller disputes are absorbed into larger ones, and the smaller party's leverage is the larger dispute's salience. Canberra's task is to keep the two files uncoupled long enough to negotiate them separately, which is exactly what Farrell was trying to do in his SBS comments.
Stakes: who wins, who loses
If the US presses the link, Australian exporters in mining services, agricultural processing and pharmaceuticals — sectors that depend on access to the US market and on complex Asian supply chains — face the worst of both worlds: tariff exposure at the border and supply-chain disclosure exposure in the boardroom. Smaller Australian firms, which are exempt from the Modern Slavery Act's reporting threshold, would absorb the tariff hit without the compliance burden that the law is being used to attack. That distributional shape is the one Beijing, Brussels and Jakarta will be watching, because it sets a precedent for how the US treats mid-sized allies that have copied its own supply-chain disclosure template.
The structural read is that we are watching a slow, low-visibility renegotiation of the post-2018 consensus that trade liberalisation and labour-rights enforcement can be pursued in the same sentence. The Trump administration's view is that they cannot — that disclosure regimes function as protectionism by another name. The Australian, European and Canadian view is that they must, and that supply-chain transparency is now part of the cost of admission to the US market. Farrell's denial, on 9 June 2026, is the polite Australian version of that argument. It will not be the last round.
Desk note: Monexus reports Australian trade policy from a position of structural sympathy for a US-aligned, mid-sized economy caught between its largest security partner and its regulatory peers in the EU and Canada. The story is treated as a trade and industrial-policy story, not a culture-war one.
