Businessman and federal MP Clive Palmer has holdings in more than 100 companies, according to his register of members’ interests.

Billionaire MP Clive Palmer owns so many companies, properties, cars and aircraft he can’t list them all on the official parliamentary register.

The register, tabled in federal parliament on Wednesday, includes an 11-page list of Mr Palmer’s interests – the longest of any MP.

Mr Palmer has declared specific share holdings in 94 private and 11 public companies and reveals he holds director positions at 85 companies in Australia and overseas.

He also writes that he’s a shareholder in, and director of, other companies “from time to time, as listed with ASIC”.

Mr Palmer’s list of other assets valued at more than $7500 includes vintage cars, boats, paintings, planes and helicopters, albeit with no specific details.

The member for Fairfax also notes his ownership of properties in Brisbane, the Gold Coast, Sunshine Coast, Jandowae, Port Douglas and on Bora Bora in French Polynesia.

There are no specific details of his real estate holdings.

Mr Palmer also address the issue of the declaration of gifts valued at more than $750, which all MPs must routinely declare.

“In my capacity as a director of (private) companies … gifts are often sent to me for those companies to evaluate the suitability for their businesses,” he writes.

“I have therefore signed an acknowledgement with those companies that all gifts received by me during my term as a member of the House of Representatives will be on the account of those companies and not received on my behalf personally”.
