That’s according to a report conducted by the Australian Workplace Innovation and Social Research Centre.

The findings of the report, released on Friday, show the estimated financial impact of Joe Hockey’s May budget on every Australian electorate by the year 2017.

Removal of the carbon tax and the scrapping of the school kids income bonus were taken into account when tabling results. Outcomes were reached by breaking down and applying each of the government’s budget saving measures.

While the Prime Minister promised the carbon tax will leave Australian families $550 better off each year, data from the Workplace Innovation and Social Research Centre suggests otherwise.

Fifteen of the 16 hardest hit electorates are held by Labor MPs, the study concluded.

Moreover, the electorates of North Sydney and Warringah, held by the Treasurer and Prime Minister respectively, are among the least affected.

Hume – a seat which spans from Cootamundra in the west to Picton in the east – finished midfield on the list of most affected electorates.

The study found the average household will be stung to the tune of $360.50 in the 2017/18 financial year.

Neighbouring households in the ACT, meantime, fared better.

Ratepayers in the north Canberra electorate of Fraser will be $199 worse off, the report concluded. Those in the south of the ACT, in the seat of Canberra, will forgo $160.

The number crunching contradicts both the government and Opposition.

Member for Hume, Angus Taylor, last month spruiked his government’s axing of the carbon tax. A businesswoman in the town of Young, Mr Taylor claimed, was set to save $1200 on her next electricity bill – savings directly attributable to the carbon tax removal.

“Hairdresser Melissa McColl from Young told me her power bill was set to fall by $1200,” Mr Taylor wrote on his Facebook page.

“Melissa employs many young people, and she was looking at having to cut back on staff but for the expected saving.”

The study also makes a mockery of comments from Opposition leader, Bill Shorten, who claimed the May budget would leave a single income family surviving on $65,000 per annum nearly $6000 worse off each year.

“A single income family with two children, earning $65,000 a year, will be $6000 a year worse off because of the Prime Minister’s broken promises on the GP tax, the petrol tax, family payments and cost of living,” Mr Shorten told Parliament in June.
