Business failures and setbacks

Calidus administration and impaired receivable

Macmahon reported that client Calidus entered administration in June 2024 and its Warrawoona operations entered care and maintenance. Macmahon fully impaired an A$31.8m receivable at FY2024; management then expected a possible route to recovery through the receivers’ sale or recapitalisation process. Final recoveries are not established here.

Evidence gaps

  • Independent verification of education, credential status, full prior-employer tenures and individual outcomes is incomplete.

  • Focused public-source screening is not a comprehensive court, regulatory, criminal, sanctions or credential check; some historical employer records and local-language sources were not reviewed.

  • Final recoveries on the Calidus receivable and individual decision-making are not established.
