It was nothing more than a wealth re-distribution tax, high income earners were hit with increased power bills, lower income earners & welfare recipients etc. were given subsidies to carry on as usual.
Billions of $ were given to energy producers in the form of subsidies...which were overly generous and they are now bleating about....
Don't get me wrong...I think climate change is real and burning fossil fuels is having a big impact.
The problem for Oz was we were acting like a bunch of vegetarians running an abattoir. Taxing local coal fired energy producers, while they very same coal was being shipped to places like, Pakistan, who claimed their "new" coal fired plants were "cleaner", then claiming a carbon credit to burn the same australian coal !!
A stupid tax. Glad to see it gone.
