FOWLER MP Chris Hayes says the average Fairfield family will be $5000 worse off because of the the impact of the 2014 federal budget.
Mr Hayes, the chief opposition whip, said the cuts proposed in the budget would have a significant affect on his constituents because the area he covers is a lower socioeconomic area, with an average wage $34,000.
His state Labor colleague Macquarie Field MP Andrew McDonald, who is also a pediatrician, said the $7 co-payment introduced by the government had already led to a drop in the number of people attending local doctors' surgeries.
"This is the worst thing that's happened to public health in the past 30 years," Dr McDonald said.
"It will completely destroyed our free health care system, it's been designed like a slippery slope and eventually we'll have paid health care."
Hughes MP Craig Kelly, a Liberal, said the tough measures to be introduced in the budget were necessary to repay the nation's debt.
"These cuts are going to be unpopular, but we have to make the hard decisions for the betterment of the country," Mr Kelly said.
"The $7 co-payment to go to the doctor will be cut off at 10 trips to the doctor per year and most of that funding will go towards a $20 billion medical research fund, which will more than double the medical research spend in this country."
Mr Kelly said it was easy for a government to give away money and run up debts, but his government was acting in the best interests of the country.
Mr Hayes said Fowler will also be greatly affected by changes to Newstart.
"Fowler is one of the highest unemployment areas in the country, with close to double the national rate. Having to wait six months will cause all sorts of social problems, including a potential increase in the crime rate."
