The ACT Liberal Party has called for a comprehensive federal audit of all infrastructure spending in Canberra, citing corruption findings involving the Construction, Forestry, Maritime, Mining and Energy Union (CFMEU).

The opposition is urging Finance Minister Katy Gallagher to scrutinize Commonwealth contracts in the nation's capital to ensure public funds are not compromised by the union's alleged misconduct.

The demand for an audit comes as political scrutiny intensifies around the CFMEU, which has faced significant regulatory and legal pressure in recent months.

The ACT Liberals argue that the integrity of federal infrastructure projects in the capital must be verified given the union's historical influence in the construction sector and the newly surfaced corruption evidence.

This development adds to a broader wave of regulatory and political challenges facing major Australian institutions.

The Reserve Bank of Australia recently confirmed it is reviewing its relationship with KPMG Australia, marking a significant escalation in regulatory pressure on the firm amid growing concerns over professional standards.
