2021 site compliance audit with qualifications

2021 · documented · low materiality

An external consultant's 2021 Isaac Plains East annual EPBC compliance report listed Pires among staff interviewed and found qualified compliance with relevant conditions for its stated reporting period. It also recorded rehabilitation monitoring was completed after the reporting period, and expressed the audit's limitations. This is not proof of continuing compliance or personal responsibility.

Attribution: Individual involvement documented. The audit names Pires as one of the staff interviewed. It does not attribute the compliance findings solely to him.

Evidence gaps

• This partial screening does not include dedicated person-specific searches for every fraud, safety, environmental, governance and legal topic, all material prior-employer records, original court or regulator registers, or independent credential verification.

• One broad name-and-employer query is repeated across topic entries; it represents one actual search, not nine separate topic searches.

• The exact continuation of some roles at 31 October 2026 is inferred from the latest accessible dated company materials and undated leadership page, not independently confirmed.

• The eventual status of the 2025 water infringement notices and any related investigation is not established.
