Around 3.5 million Australians have received JobKeeper support under the $70 billion scheme, but some areas have been more reliant on the plan than others.
New data to be released by Treasurer Josh Frydenberg and seen by News Corp on Thursday names the postcodes claiming the most JobKeeper payments.
It comes amid debate on whether the payments should be extended to certain industries and groups. In its latest economic outlook, the Organisation for Economic Cooperation and Development (OECD) called on the government to extend the JobKeeper program.
"Extraordinary policies will be needed to walk the tightrope towards recovery," OECD chief economist Laurence Boone said.
"Higher public debt cannot be avoided, but debt-financed spending should be well-targeted to support the most vulnerable."
The report said “some income support measures may need to be extended beyond their September expiry date”.
However, the government has refused to extend the scheme, leaving industries like aviation and tourism in the lurch.
And the new Treasury data reveals the areas that are also eyeing the September deadline with the most concern.
