It was a key objective of the Budget and has become the Rudd government's mantra: "to put downward pressure on inflation".

Even Federal Treasurer Wayne Swan said the Budget was "focused on dealing with the inflationary challenge".

But according to secret Treasury advice obtained by Seven News through Freedom of Information laws, it may not have been focused enough.
