An investigation is likely into one of the federal government's biggest land deals, the CSIRO giant Ginninderra Project, after the lead executive on the massive development program was sacked.

Sources close to the government organisation say the project, under the stewardship of former general manager for business and infrastructure services Mark Wallis, is now set to come under scrutiny after Mr Wallis lost his job at CSIRO over alleged "breaches" involving a corporate credit card.

The allegations against Mr Wallis are now being investigated by the Australian federal Police.
