The Independent Commission Against Corruption (ICAC) has continued its high-profile Operation Navarra public inquiry, with former Parramatta City Council chief executive Brett Newman facing extensive cross-examination over allegations being examined by the anti-corruption body.

Operation Navarra is investigating whether current or former council officials, contractors and associated individuals engaged in corrupt conduct relating to procurement processes, public administration and the awarding of contracts connected to Parramatta Council operations. The inquiry forms part of a broader examination of governance practices within one of New South Wales' largest local government authorities.

During Wednesday's hearing, Newman, who was dismissed from his role as chief executive, was questioned in detail by counsel assisting the commission about a range of decisions made during his tenure. The hearing focused on communications, management practices and interactions with contractors and other council figures that have become central to the commission's investigation.

ICAC counsel challenged Newman on various matters raised through documentary evidence and witness testimony presented earlier in the inquiry. The former council chief was asked to explain decisions relating to council projects, procurement procedures and relationships with individuals whose conduct is also being examined as part of Operation Navarra.

The inquiry has attracted significant public attention because of its potential implications for local government governance and accountability. Parramatta is one of Australia's fastest-growing urban centres, and the council oversees major infrastructure, planning and development projects involving substantial public expenditure.

Throughout the hearing, Newman responded to questions regarding his actions and denied wrongdoing. As is standard in ICAC proceedings, the inquiry is tasked with determining whether evidence exists that may constitute corrupt conduct, rather than deciding criminal guilt.

The commission has heard evidence from numerous witnesses over recent weeks, including former council staff, contractors and external advisers. Large volumes of emails, internal documents and official records have also been tendered as part of the public hearings.

Operation Navarra has examined allegations concerning procurement arrangements, council decision-making processes and whether public resources were used appropriately. Investigators are assessing whether any individuals involved improperly benefited from council contracts or exercised influence in ways inconsistent with public sector obligations.

ICAC hearings are conducted publicly to promote transparency and public confidence in government institutions. However, findings have not yet been made, and the commission's work remains ongoing.

At the conclusion of the inquiry, ICAC may make findings regarding conduct, recommend disciplinary action, suggest reforms to governance procedures or refer matters to prosecutorial authorities if evidence of criminal offences is identified.

Legal representatives for individuals appearing before the inquiry have repeatedly stressed that no adverse findings have been made and that all parties are entitled to procedural fairness throughout the process.

The hearings are expected to continue over coming weeks as additional witnesses provide evidence and further documentation is examined.

It is important to note that ICAC investigations are fact-finding processes. The allegations and issues being explored during Operation Navarra remain unproven unless and until formal findings are made by the commission or determined by a court.
