SYDNEY - More than 80 percent of Australians are worried about their ability to meet debt repayments in the future, a survey by data intelligence company Veda showed on Monday.

The biannual survey found 82 percent of respondents were worried about their ability to pay their debts in the future, compared to 75 percent a year ago.

The survey also found that one in five Australians was struggling to pay off their current credit commitments.

However, about 29 percent of Australians were considering applying for more credit in the next six months, the survey found.

"It is concerning that there are people struggling with their current debt levels but are turning to more credit as the answer, potentially edging closer to a debt spiral," Veda senior adviser Matthew Strassbourg said in a statement.

The survey found people in 25-34 age group were the most worried about their ability to repay debt and the most likely to borrow more in the next six months.

About 70 percent of this age group had received help from a family member to repay debts compared to about 35 percent for the rest of the population, the survey found.
