Just like the now-fading labor push to put the GST front and centre, the push to force costings out, is just not going anywhere. Nice try, and in a normal environment it would be a good question.
But given labor's appalling record, it just a joke. Nobody cares, because they know that whatever the costings are, they will be less than the ongoing incredible cost of labor.
I know of a young individual who is fighting to raise $18000 for a kidney operation. All sorts of locals are chipping in. Contrast that with Kevin Rudd spending $800,000 plus for a four hour visit to Afghanistan.
