在独立反腐委员会对新州自由党分支堆积丑闻的Operation Rosny调查中，前总理多米尼克·佩罗特的弟弟让-克劳德·佩罗特作证时公开了与逃亡开发商让·纳西夫之间的窃听电话录音。[1]录音显示纳西夫吹嘘在城堡山地区安装了数百名新党员，并建议向佩罗特兄弟支付10万美元以支持预选。[1]
让-克劳德·佩罗特在作证中承认收到来自涉嫌非法捐赠渠道的2.5万美元，该笔款项以月度5000美元的方式分解支付，同时还直接从被禁止捐赠人迈克尔·奥哈拉处收取了8万美元。[1]
独立反腐委员会指控纳西夫向杰里米·格林伍德、克里斯蒂安·埃利斯和查尔斯·佩罗特提供了总计200万美元的贿赂。[1]让-克劳德·佩罗特曾在美达隆金融公司工作期间（2020年1月至2023年3月）为纳西夫管理投资。[1]此后，他因该反腐调查而被天主教学校新州组织解雇。[1]
Jean-Claude Perrottet, brother of former New South Wales Premier Dominic Perrottet, testified before the Independent Commission Against Corruption (ICAC) in its Operation Rosny investigation into Liberal Party branch stacking, revealing intercepted telephone recordings that documented alleged attempts to influence party preselections through financial inducements [1]. The recordings captured escaped developer Jean Nassif boasting about recruiting hundreds of new party members in the Castle Hill district and proposing to pay the Perrottet brothers A$100,000 to secure their support for a preselection [1].
During his testimony, Jean-Claude Perrottet acknowledged receiving A$25,000 from a company through installments of A$5,000 per month, as well as A$80,000 directly from prohibited donor Michael O'Hara [1]. Nassif's alleged bribery scheme extended further: ICAC charged him with offering A$2 million in inducements to Jeremy Greenwood, Christian Ellis, and Charles Perrottet [1]. From January 2020 to March 2023, Jean-Claude Perrottet had managed investments for Nassif while employed at Medallion Financial, a position that ended following his involvement in the ICAC investigation [1]. His former employer, a Catholic education organization in New South Wales, terminated his employment in connection with the inquiry [1].
