The Centre for Social Impact has painted a grim picture of the financial health of Australian households, reporting that almost two-thirds of adult Australians face some level of financial stress or vulnerability - a much higher level than in other surveys of financial stress.The Centre has published a report, Financial Resilience in Australia, which says that only 35.7 per cent of adults are financially secure.It found two million people experience "severe or high" financial stress.Other findings are that one on four people report having experienced difficulty accessing financial services in the past 12 months and 48 per cent have only a basic understanding of financial products and services.Around 17 per cent said they were over-indebted or were just managing to make their repayments. Half said they had limited or no savings.On the positive side, 49 per cent reported that they followed a budget and 56.8 per cent reported that they make extra repayments on personal loans and 28.5 per cent make extra repayments on home loans.The Centre for Social Impact is a collaboration of the University of New South Wales, Swinburne University of Technology and the University of Western Australia. Its figures are based on a survey of 1496 respondents over 18 conducted by Roy Morgan Research.The finding that two million people experience severe or high stress is based responses from people in this group, who say they face at least one of the following issues: they have trouble paying a debt or meeting cost of living expenses; they have limited access or unmet demand for credit or insurance; or they have limited understanding of financial products.Factors affecting financial resilience include income level, education, housing and mental health.
