Independent Senator Nick Xenophon and Greens leader Christine Milne moved a motion this week calling for the public release of documents relating to the allegations surrounding Securency and Note Printing Australia (NPA).

Senator Xenophon also called for any written advice provided to the government by the central bank.

However, two major parties have combined forces in the Senate to put a halt to the attempt to make the documents public, which relates to corruption and bribery allegations at the two subsidiary companies of the Reserve Bank.

NPA, a wholly-owned subsidiary of the RBA, and its part-owned Securency have been under investigation since mid-2009 over allegations they bribed foreign officials to gain contracts.

The Greens said they would push for a royal commission into whether the central bank covered up evidence of bribery activity after fresh allegations were aired on ABC TV earlier this week.
