The JobKeeper program and the Coronavirus Supplement have both been extended.
Business Port Augusta Chairperson Darren Sherriff said the economic support for local businesses and their workers is helping local communities through the Covid-19 pandemic.
"The extension is imperative at the moment because as much as South Australia hasn't been hit as hard as other states, we have still got some issues to come and we have still got fallout from the previous shutdown," he said.
"We have been lucky so far, but as far as the economy goes .. even for me personally, I know it is going to affect my sales figures by September/October which is when it was originally due to finish."
According to the Grattan Institute thinktank, close to 9 per cent of people living in the federal Grey electorate have lost their jobs during the global pandemic.
Regional electorates have been significantly more affected than metropolitan counterparts.
"I think the whole package has been reasonably generous from the start, but the timeline is what I think needs attention," Mr Sherriff said.
"There has been a lot of knee jerk reaction and now there needs to be some serious planning over the next 12 months to two years .. we need to plan ahead for how its going to impact unemployment and the economy."
The JobKeeper payment will continue at its current level until September 27, after which it will be extended for a further six months.
A two-tiered payment will also be introduced so as to better reflect the pre-Covid-19 income of payment recipients.
Specifically, from September 28 until January 3 next year, the two payments will be $1,200 and $750 per fortnight, with the lower payment for employees who worked less than 20 hours a week in the month of February pre-Covid-19.
From January 4 to March 28 next year, the two payments will be $1,000 and $650.
The temporary Coronavirus Supplement for those on income support will also be extended until December 31, 2020. The $550 per fortnight supplement will continue until September 24.
From September 25 until December 31, the supplement will be $250 per fortnight. The changes were outlined last week.
