What else ?

Definitely a "chickens coming home to roost" tax, for when the libs have to fix the financial mess caused by the ALP,

A clean water levy (tax)... we effectively have one already to pay for desalination plant in Sydney,

A clean air tax, probably will happen,

A large family tax, if you have more than 1 child, to offset the future contribution to global warming arising from your offspring, and ideally deter parents from having large families, those with no kids should get a rebate IMHO

A future gas-guzzler tax, to coax the leadfoots out of overpowered vehicles into hybrid or electric vehicles when they become viable;

A large vehicle tax, to persuade buyers of SUV's it's time to downsize, though making car parking spaces smaller would effectively achieve the same;

A toilet tax, based on how many 'loos you have in the house;

An excess shower tax, metered, to wean teenage daughters off 45 minute showers...
