Large parts of Sutherland Shire are among areas in Australia that are most reliant on the JobKeeper program.
Cronulla, Oyster Bay, Gymea, Engadine and Menai areas are in the highest decile, while most other shire suburbs are in the second most dependent bracket.
The $1500 a fortnight JobKeeper subsidy is due to end in September but the government is considering further jobs support after receiving a Treasury review.
Prime Minister Scott Morrison said an announcement would be made in the third week of July.
"We will have policies in place - we've got to get the decisions right, that's why we gave ourselves six months to give us time to decide what the next step will be," he said.
An index developed by actuarial and data analytics firm Taylor Fry identifies postcode areas most likely to be receiving JobKeeper based on Bureau of Statistics and census data.
Occupations and income of residents form a key part of the analysis and hard-hit shire suburbs have very high numbers in the aviation and building installation industries.
Postcodes with the highest proportion of workers receiving the payment are in the 90-100 decile, coloured dark red, moving down to those with the least proportion, coloured green.
