A major corruption investigation by the NSW Independent Commission Against Corruption (ICAC) has entered public hearings, with Operation Rosny examining allegations involving political donations, internal party influence and possible breaches of NSW electoral funding laws.

The inquiry is focused on claims involving people connected with the NSW Liberal Party, property developer Jean Nassif, hotelier Michael O’Hara, Catholic Schools NSW chief executive Dallas McInerney, and other individuals. ICAC has stated that the investigation concerns whether certain political donations were improperly made, not properly declared, or exceeded legal donation limits.

One major area being examined is whether members of a conservative Liberal faction known as the “Reformers” received or organised political donations that may have breached electoral funding rules. Investigators are looking at whether donations were used to support activities including recruiting or renewing party members.

The inquiry is also examining allegations involving property developer Jean Nassif and whether political payments were connected to attempts to influence government decisions or advance business interests. ICAC has emphasised that these are allegations being investigated and that the inquiry will determine whether any conduct breached relevant laws.

Another part of the investigation relates to allegations that payments involving organisations or businesses may have been used to support political activity. The commission is examining whether arrangements involving Catholic Schools NSW and other entities complied with electoral donation requirements.

During early hearings, evidence has included discussion of political relationships, factional activity and alleged efforts to influence internal party structures. Some witnesses have provided evidence about donations and their involvement with Liberal Party groups.

Michael O’Hara, a hotelier named in the inquiry, has appeared before ICAC and provided evidence about donations linked to the Liberal Party faction. Reports from the hearing indicate he acknowledged involvement in funding activities but said his motivations were political rather than improper.

The inquiry has attracted significant attention because of its potential implications for political transparency and accountability in NSW. ICAC investigations do not automatically mean individuals have committed offences; the commission examines evidence and may make findings or recommendations after considering all information presented.

Several political figures have been mentioned during discussions surrounding Operation Rosny, although being mentioned in an inquiry does not mean a person is accused of wrongdoing. ICAC has identified the scope of its investigation and will continue gathering evidence through public hearings.

The public inquiry is expected to continue for several weeks, with witnesses, documents and other evidence examined as investigators assess whether electoral laws were breached and whether any improper conduct occurred.

The outcome of Operation Rosny could have wider consequences for political donation rules, party governance and transparency standards across New South Wales.
