Australians feel their country is no longer the land of the fair go, according to research from peak welfare body the Australian Council of Social Service.

Three-quarters of the people who took part in the study felt the gap between rich and poor was widening and almost 60 per cent felt income and wealthy inequality was bad for society.

The report follows ACOSS research that found that someone in the highest 20 per cent of income earners in Australia has about 70 times more wealth than a person in the lowest 20 per cent.

The council will release the new findings compiled by Ipsos at its national conference, which begins in Sydney on Thursday.
