Nationals backbencher John "Wacka" Williams says everyone has to help with budget repair, insisting the federal government's proposed superannuation changes will leave him out of pocket.

Senator Williams says he doesn't have a lot of super as he prepares to retire in three years but the changes will mean he'll pay an extra $9000 a year.

"We've all got to take a bit of pain," he told parliament.
