Independent Senator David Pocock purchased billboards to pressure Treasury Minister Jim Chalmers over a proposed tax on gas exports [1].

The move signals an escalating effort by crossbench members to force the government to implement more aggressive resource taxation. Pocock said a tax on gas exports would generate significant revenue while addressing climate concerns, and ensuring a fair contribution from the resources sector [1].

During an appearance on the ABC News program *Insiders* on April 20, 2026, Pocock discussed the fiscal measures he is championing [1]. The conversation focused on the potential for a gas export tax to stabilize the budget and fund public services. Pocock also raised the issue of Petroleum Resource Rent Tax (PRRT) revenue, and proposed changes to capital gains tax as part of a broader strategy to reform how Australia taxes its natural resources [1].

The use of public advertising to target the Treasury Minister represents a shift in tactics for the senator. By moving the debate from the Senate floor to public billboards, Pocock said he aims to increase political pressure on Minister Chalmers ahead of future budget cycles [1].

Treasury Minister Jim Chalmers has faced ongoing scrutiny regarding the government's approach to resource rents. The debate centers on whether the current tax framework allows companies to avoid paying a fair share of the profits derived from the country's natural gas reserves [1].

Pocock's strategy links fiscal responsibility with environmental goals. He said the resources sector must contribute more to the national treasury to offset the long-term costs of climate change, and the transition to renewable energy [1].

The use of public billboards by a sitting senator indicates a breakdown in traditional legislative negotiation, suggesting that independents may use public shaming and high-visibility campaigns to secure concessions from the Treasury. This approach leverages public sentiment regarding corporate tax fairness to create political leverage for resource-based fiscal reforms.
