Shadow Portfolio — 24 March 2026

Senator McKenzie, Leader of the Nationals in the Senate, used two Senate interventions on 24 March to press a coordinated opposition case on the fuel security crisis, combining a procedural call for a national biofuels strategy with coalition support for a substantive motion on transport infrastructure.

In the first intervention, Senator McKenzie called on the government to immediately establish a national biofuels and low-carbon liquid-fuel strategy [TA-260324-senate-dd516f85acd4:s162]. She cited years of unresolved consultations by the transport minister as evidence of inaction and framed biofuels as a practical supply-side buffer against further fuel shocks rather than a long-term climate instrument [TA-260324-senate-dd516f85acd4:s162].

The Nationals pointed to New South Wales and Queensland ethanol mandates as existing models the federal government could build on, and explicitly rejected any response centred on relaxing sulphur standards — positioning the coalition as pro-biofuels rather than pro-deregulation. Senator McKenzie called for the matter to be elevated to National Cabinet and attacked the government's appointment of the current fuel tsar, arguing the role demanded logistics expertise, not a climate policy background.

On the transport infrastructure motion, Senator McKenzie announced coalition support and laid out a clear jurisdictional argument: public and active transport investment belongs with states and territories, not the Commonwealth [TA-260324-senate-dd516f85acd4:s167]. The federal role, as the Nationals define it, runs to supply-chain data sharing, national ethanol mandates, fuel rationing frameworks, and GST relief for the transport industry — a concrete policy menu that differentiates the coalition position from the government's response.

Senator McKenzie attributed the underlying crisis to the Middle East conflict and characterised the Minister for Climate Change and Energy's handling as a failure, pointing to the government's own shift to National Cabinet coordination as evidence that ministerial management had broken down [TA-260324-senate-dd516f85acd4:s167].

The two interventions are plainly coordinated in message. Both frame the government as having been slow, mismatched in expertise, and reactive. Both advance biofuels and ethanol mandates as the central supply-side answer.

The National Cabinet call in the procedural intervention and the jurisdictional framing in the motion together construct an argument that the government has failed at both levels — federal ministerial management and intergovernmental coordination. The Nationals' policy offer is specific enough to anchor future scrutiny: supply-chain data sharing, national ethanol mandates, fuel rationing, and GST relief each constitute a testable commitment the government can be pressed against.
