INTERACTIVE: Pressure mounts to maintain coronavirus income support as report predicts dire consequences

That's, according to modelling by Deloitte Access Economics released by the Australian Council of Social Services.

The modelling forms part of an 89-page report estimating the economic impacts of lowering levels of income support payments.

September 25 was the first day of the reduced coronavirus supplement, with recipients getting $300 less per fortnight than when the payment was introduced.

The federal government plans to retain the $250 fortnightly supplement until December 31.

It has yet to announce what will happen after then, though Prime Minister Scott Morrison in July said the government had "no intention of... going back to the original JobSeeker base payment".

Reducing, then removing, the coronavirus supplement would strip $31.3 billion from the Australian economy over the course of two financial years, according to Deloitte.

An average of 145,000 full time jobs were likely to be lost during that period, with most of the damage likely to take place in 2021-22.

No Wimmera or Grampians areas were listed in the most remote local government areas in Australia, when it came to modelling localised impacts and the communities that would be hardest hit.

Reducing, then removing, the coronavirus supplement would slash more than 246 jobs from Ararat Rural City.

Spending was predicted to drop by $3309 per person, on average, by the end of 2021-22. The local government area's economic output was estimated to drop by more than $2642 per person.

Horsham municipality is predicted to lose 337 jobs in a year if income support is reduced, as recipients struggled to afford goods and services.

Consumption would drop by $2698 per person by the end of 2021-22, and the city's output was predicted to drop by $2154 per person.

The report says areas with low levels of JobSeeker applications are often protected due to their strong links to mining or agriculture, or that had low unemployment due to strong tourism sectors before the pandemic.

A spokesperson for Deputy Prime Minister Michael McCormack said the government had always said it would review the coronavirus supplement later in the year.

"The government has already announced unprecedented support through more than $300 billion in emergency response measures," the spokesperson said.

"Any suggestion that the government is reducing spending is simply not correct.

"The government has to carefully balance that unprecedented support with appropriate incentives to help people re-engage with the workforce as jobs continue to come back as the economy re-opens."

The spokesperson quoted one of Mr McCormack's recent press conferences, at which the deputy prime minister said: "The best form of welfare is a job."

"If you don't have a job and there's somebody offering you a job and offering you good pay and good conditions, then pitch in. Have a go."

The spokesperson reiterated the government's commitment to ensuring all of Australia bounced back from the COVID-19 pandemic.

"We will continue to invest in job-creating infrastructure, business support and other initiatives to help people get back to work sooner," they said.

Australian Council of Social Service chief executive Cassandra Goldie called on the government to move quickly to legislate a permanent, adequate JobSeeker rate.

"The doubling of Newstart at the start of the pandemic came as a huge relief," Ms Goldie said.

"After 26 years without a real increase to Newstart, people without paid work were finally able to afford the basics.

"But they now face a deeply uncertain future, with these devastating cuts to their already tight budgets and 28 people receiving JobSeeker for every job vacancy in regional areas."
