Business failures and setbacks

Resource Development Group administration

FY2024–September 2025 · documented · medium materiality

RDG’s FY2024 annual report named this executive as its non-executive director. MinRes reported RDG entered voluntary administration in July 2025 after drawing A$145m under a MinRes loan at June 2025. In September creditors approved MinRes’s asset purchase proposal; MinRes said its board made the acquisition decisions with Ellison and its RDG nominees excluded. Contemporaneous July 2025 reporting also identified both roles at administration, based on the RDG website; precise cessation dates remain unconfirmed.

Attribution: Role overlaps event; causation unproven. Contemporaneous reporting identifies the directors’ roles, but their personal decision-making and responsibility for the company’s failure are not established.

Relevance: Relevant to capital allocation and oversight.
