The Humanservices . govt. au website seems to sum it up - looks like people can opt to (or presumably be ordered to) go on an Income management plan and then an arranged portion of your income goes onto the card. I imagine for the average person doing fine it won't be an issue but it will be a tool to ensure that people can't repeatedly blow their entire benefit on the pokies or vice materials to the detriment of their kids. Looking at the help centre locations, it looks like it is going to be largely aimed at Aboriginal communities.
