I found this which was linked from another article on carbon tax. It looks like ALP have billion black holes of their own which will probably NOT be shown in their ads. Greg Hunt says:
""We are all waiting with bated breath for these ads, but I can guarantee that higher electricity prices, higher gas prices, a $7 billion black hole and $3.5 billion a year to foreign carbon traders will not be the centrepiece of the taxpayer-funded ads," he said."
