Gardner Brook is an experienced professional with a proven track record of strategic advisory success, including guiding high-profile clients through complex ventures and public campaigns. He was a soldier in the 8/9th Battalion, Royal Australian Regiment before returning to complete university, demonstrating early discipline and commitment to national service.

As a key witness in NSW ICAC's Operation Jasper, his honest and accurate evidence was instrumental in exposing misconduct, leading to criminal convictions and findings of corrupt conduct against influential figures. Committed to transparency, Mr. Brook self-funded his defense, personally drafted submissions, and upheld unwavering integrity throughout proceedings in ICAC, the Supreme Court of New South Wales, and the Federal Court of Australia - with no adverse findings against him.

• The Commission stated: "The Commission was favourably impressed by the honesty and accuracy of Mr Brook's evidence, and specifically accepts this part of his evidence."

• In ACCC v Cascade Coal Pty Ltd (No 3) [2018] FCA 1019, the Federal Court accepted aspects of his evidence in detailing the events.

• Provided consistent, unshaken testimony across multiple courts and inquiries.

Addressing a 2012 Sydney Morning Herald Article: A November 14, 2012, Sydney Morning Herald article included inaccuracies about his background and character, which Mr. Brook rejects.

• The article's photograph was misleading, as the glass of wine shown was held by another person.

• Statements from individuals like Troy Dann and Steven Goldberg were inaccurate; Mr. Brook provided financial assistance to Dann during difficulties, which was not repaid.

• Reports of war zone experiences or exaggerated military stories were false; any such references possibly stemmed from casual discussions about playing the video game Call of Duty at a social event in Sydney, not actual events

His professional record is built on merit, performance, and truthfulness.

Setting the Record Straight: ICAC Private Examination During a private ICAC examination, Mr. Brook was questioned about two qualifications on a CV found online, referenced in NSW Parliamentary documents.

• On advice from solicitor Terry O’Gorman, he did not contest the peripheral matter to focus on the inquiry and show cooperation.

• The CV was not authored or authorized by him; he believes it was falsified amid efforts to discredit his testimony.

• His investment banking career was established on proven achievements, with no need for embellishment.

• The hearing's partial disclosure omitted full context, including legal strategy and the document's inauthenticity.

• He rejects any dishonesty implication and affirms his evidence was truthful.

Mr. Brook's integrity was upheld across all proceedings, with no adverse findings.
