The Australian Greens have unveiled an ambitious economic platform offering a $21 weekly tax cut to workers, pledging to fund broad relief by extracting fresh revenue from the nation's resource giants.

Addressing the National Press Club in Canberra, Greens leader David Shoebridge outlined the blueprint, framing the minor party not merely as a crossbench foil but as an uncompromising political alternative seeking to ultimately "replace Labor".

ABC News Business reported that the centrepiece of the address combines tangible household relief with substantial hikes in welfare payments, anchored by an overhaul of the fiscal framework governing fossil fuel and mineral exports.

Mining windfalls in the crosshairs

At the core of the Greens' proposal is an aggressive attempt to redirect the immense earnings of the nation's multinational exporters back into the public purse. Outlining the strategy, the party declared its intention to pursue what it described as "rivers of gold" flowing from the resources sector.

The plan targets super profits across coal, gas, and mineral extraction, arguing that existing royalty regimes fail to deliver an equitable dividend during periods of elevated global commodity prices. Under the proposal, tightened tax regimes would ensure extractive companies contribute considerably more to Commonwealth coffers, creating an expanded revenue base for domestic programs.

Industry groups have historically resisted windfall levies, warning that higher sovereign tax burdens could temper capital investment and threaten jobs in major export hubs across Western Australia and Queensland. Nevertheless, the party contends that prevailing export arrangements disproportionately enrich overseas shareholders at the expense of local communities.

Cost-of-living relief and income support

The revenue generated by this revised mining tax regime would be earmarked to alleviate compounding household distress. Central to the offering is a direct tax cut worth approximately $21 a week, tailored specifically to ease pressure on low- and middle-income workers grappling with stubborn inflation and high interest rates.

Alongside the tax offset, the platform champions a substantial lift in income support payments. The policy aims to elevate standard welfare baselines above the poverty line, addressing long-standing arguments from social service groups that existing payment rates fail to cover basic essentials such as rent and groceries.

By packaging direct worker relief alongside welfare reform, the party is seeking to insulate its spending proposals against traditional fiscal critiques, insisting that profitable resource multinationals should underwrite domestic social equity.

An overt pitch to traditional Labor heartlands

The policy announcement represents a pointed ideological challenge to the federal government. By positioning the Greens as a viable economic champion for working households, Mr Shoebridge is seeking to erode Labor's support in outer-metropolitan and regional electorates where cost-of-living pressures remain acute.

While the Greens have traditionally drawn support from inner-city seats, the explicit ambition to "replace Labor" signals a strategic expansion into traditional blue-collar territory. Party strategists anticipate that workers frustrated by cautious federal fiscal policy may be receptive to direct relief funded by resource windfalls.

With Canberra facing tight legislative arithmetic in the Senate, the platform ensures that resources taxation and cost-of-living assistance will remain high on the political agenda heading into the next federal contest.
