WA minister review may not be made public

There's no guarantee a review of the financial disclosures of West Australian Transport and Finance Minister Dean Nalder will be made public, the premier says.

Colin Barnett was expected to receive the report on Thursday morning.

Mr Nalder came under the spotlight after it emerged he had not divested a stake in Fleet Network, which leases cars to public servants through salary packaging arrangements, in the 60-day time period stipulated under the ministerial code of conduct.

Next came revelations his office had nominated Darryll Ashworth, the chief executive of a property company in which Mr Nalder has invested $400,000, to attend a meeting with the Chinese consul-general and high-level state bureaucrats in August.

And on Wednesday, Premier Colin Barnett was asked about Mr Nalder's investment in a Cottesloe property with Paul Dion Thompson, a financial trader charged in April by a US federal grand jury with conspiracy to commit wire fraud and bank fraud.

Mr Barnett replied he did not know the details.

On Thursday morning, the Liberal leader said he had not yet read the review, but regarded Mr Nalder as a decent and honest man.

"Once I've done so I will consider whether it will be released at some stage," he told an online Q&A.

Mr Nalder says he sought government advice about the Fleet Network stake and appropriately disclosed his one-third investment in the one bedroom unit, which was bought before charges were laid against Mr Thompson, who has known for more than 35 years.

"I did not know Mr Thompson was facing a major investigation when I decided to invest in a property with him," he said in a statement.

"Those matters are for Mr Thompson and to suggest that in any way there is a conflict as a result of my one-third investment ... is grubby politics, desperate and offensive."
