Despite a few roadblocks in the Senate, the legislation was passed late last week and Federal Member for Hume Angus Taylor said it was good news for Australia and for Yass.

"The will of the Australian people is clear - they wanted the carbon tax to go," he said. "Labor tried to block us, the Greens tried to stop us, but Australians have prevailed."

He said scrapping the carbon tax will save the average family around $550 per year.

However Iain Fyfe, Greens candidate in the upcoming state election for the seat of Goulburn, said it was a giant step backwards for Australia.

"I'm concerned about the future, I'm concerned about the kids and I'm concerned about the fact that we don't have time to mess about," he said.

"It's not like another policy where we can say 'Oh well in five years we'll review it and if it's not working we'll do something else', this has deadlines on it that are out of our control so mucking around is bad."

The Tribune contacted Actew AGL and Origin Energy and each will update bills and backdate costs from July 1.

Mr Taylor said local producers and business owners will especially notice the reduced costs.

"Getting rid of the carbon tax is a tangible way in which the Government is helping to reduce costs for Hume businesses and farmers," he said.

"It will make it easier for them to compete and create more jobs."

ActewAGL's Acting General Manager Retail Tony Muckle said his company was working to make sure changes would take effect as quickly as possible.

"Any price reductions will be passed on to customers in full and backdated as required by law," he said.

"We are continuing to liaise with the ACCC in relation to the carbon repeal and are updating our systems and processes so we can pass on in full any price decrease as quickly as possible once the new prices have been finalised."

Origin Energy CEO Energy Markets, Frank Calabria said they've also started changing their systems accordingly.

"Origin has started a program to update its billing systems with revised usage charges that exclude the carbon price. Customers will start seeing the new prices on their household energy bills from September, and these will be backdated to July 1," Mr Calabria said.
