It is only a proposal at this stage.

Realistically there won't be anything more said officially about this until budget time next year (about mid-March) and anything that they do will come into effect 1 July next year at the earliest but it is likely that it will take much longer than that to get it all sorted out (and work out how to pay for it - specially after they are spending so much on the stimulus package now)

So people who are due before July next year are very unlikely to get anything from this one (but will still get the $5000 if they are entitled to it)
