Questions & Answers

The record, in brief

Who is Paul Gardner Brook?

Paul Gardner Brook (known professionally as Gardner Brook) is an independent strategic-risk and geopolitics analyst and a former senior investment banker (Lehman Brothers, Nomura). He publishes independent analysis at paulgardnerbrook.com.

What was his role in the NSW ICAC “Operation Jasper” inquiry?

He was a cooperating witness — never a defendant — whose evidence the courts repeatedly preferred over that of the people he testified against.

Was Gardner Brook ever charged with any offence?

No. He was a witness, not an accused, and holds a clean criminal record.

Did the courts accept his evidence?

Yes. The NSW ICAC (2013) found his evidence “designed to be generally honest and accurate”; the Federal Court (2018) found it “essentially reliable” and “entirely consistent with the documentary record” [2018] FCA 1019; and the convictions it supported were unanimously upheld by the High Court of Australia in 2026 [2026] HCA 1.

What happened to the people he gave evidence against?

Mr Brook was the cooperating witness in the proceedings — never an accused, and never charged. It was the people he gave evidence against who were convicted and jailed [2021] NSWSC 1343; the High Court of Australia unanimously upheld those convictions in 2026 [2026] HCA 1.
