The Age article is a pie in the sky piece written by.... A male.
Shared parenting in the first year is an unrealistic goal for many families due tot the fact treat women's boobs produce milk and men's don't.
That being said a family can choose for the man to take the governments paid parental leave. If they don't it's hardly the governments fault. Blame god (who apparently made men with useless boobs) or the wife (who probably wants to stay home with young bubba).
