The Coalition, led by Opposition Leader Peter Dutton and shadow treasurer Angus Taylor, has pledged to repeal Labor's recently approved tax cuts if they win the upcoming election, marking a significant shift from their previous stance on lower taxes.

Dutton argues that Labor's proposed 70-cent daily tax cut, effective in 15 months, does not adequately address the immediate financial hardships faced by families.

In place of Labor's tax cuts, the Coalition plans to temporarily halve the fuel excise from 50.8 cents to 25.4 cents per litre, which they claim could save drivers up to $750 annually.

However, AMP chief economist Shane Oliver estimates that the average savings from the fuel excise cut would be around $455 per year.

The NRMA has expressed concerns that reducing the fuel excise could negatively impact road funding, which is crucial for infrastructure projects.

Treasurer Jim Chalmers criticized the Coalition's plan, arguing it would effectively increase taxes for all Australian taxpayers amid rising cost of living pressures.

Meanwhile, the Senate has passed legislation to protect the Tasmanian salmon industry, despite protests, highlighting the ongoing political tensions.

This ongoing conflict between the Coalition and Labor underscores their differing approaches to tackling cost of living challenges for Australian families.

Dutton plans to announce the fuel excise policy in his budget reply speech, emphasizing the need for immediate financial relief for families.

He stated that the Coalition's proposed fuel excise cut would cost $6 billion in forgone revenue but would be a more efficient use of funds compared to Labor's tax cuts.

Taylor confirmed that the Coalition would repeal Labor's tax cut top-up of a maximum of $10 a week, deeming the current measures inappropriate.

Overall, the Coalition has criticized Labor's tax cuts as insufficient and poorly timed, emphasizing the urgency for immediate relief for struggling families.
