Average household wealth has exceeded $1 million for the first time, but the distribution of wealth across the nation is deeply unequal, according to research from the Australian Council of Social Services and University of New South Wales.

The report, released on Wednesday, is based on 2017-18 figures.

ACOSS chief executive Cassandra Goldie says it is a scary premonition of the level of wealth inequality the country will reach during the COVID-19 pandemic.

"Even before this crisis the highest 20 per cent of households had nearly six times the income of the lowest 20 per cent, and the average wealth of the top 20 per cent was some 90 times that of the lowest 20 per cent," she said.

Fresh GDP figures announced on Wednesday showed the nation had entered a recession as a result of the lockdowns to suppress the COVID-19 pandemic, its first since the early 1990s and its deepest since the 1930s Great Depression.

The executive director of Anglicare Australia, a partner of ACOSS, says the report also showed people on the lowest incomes had almost no savings or assets to weather a crisis.

Kasy Chambers says that means the pandemic will push wealth inequality to eye-watering heights if much-needed social supports don't remain in place.

"1.6 million Australians are now out of work. Many more are at risk of their losing jobs, and some will never go back to full-time hours," she said in a statement.

"They will be recovering from this pandemic for months and years to come. They need certainty."

St Vincent de Paul Society and Anglicare Australia, both partners of ACOSS, have joined the organisation in calling for a permanent increase to the unemployment JobSeeker payment.

"There are many things we can't control right now, but what we can control is ensuring people on the lowest incomes have enough to get by and rebuild their lives," Dr Goldie said.
