South Australians will face another hike in the Emergency Services Levy (ESL) this year to pay for the January Sampson Flat bushfire response.

The State Government proposed to raise the intake from the levy to $285.7 million in 2015-16, a $19.8 million increase on this financial year.

It would equate to a $23, or a 9 per cent rise, for a metropolitan residential property worth $426,400.

A metropolitan commercial property worth $1.5 million would face a 10 per cent increase of $187, while industrial properties face an additional $178.

The increases will be smaller in regional areas, where discounts apply, and there would be no increase for ESL on vehicles and pensioners and low income earners will continue to receive concessions.

The State Government said the increase would help pay for extra equipment and training, costs incurred from the bushfires and cancer compensation for CFS volunteers.

Last year Treasurer Tom Koutsantonis removed a general remission on the ESL, sending bills soaring and generating anger from residents, land owners and CFS volunteers.

It increased by about $150 for people with a $400,000 home and about $370 for people with a $1 million property, in what the Government said was an attempt to compensate for federal budget cuts to health and education in 2014-15.

Farmers were hit especially hard. Many have multiple property titles under their care and some said they had faced increases beyond 1,000 per cent.

The "tax" prompted widespread protests from CFS volunteers, many who are farmers and who threatened to refuse to fight fires on government land in response.

The Government says additional ESL revenue will cover: $7.5 million for the emergency services response to the Sampson Flat fire

$7.5 million for the emergency services response to the Sampson Flat fire $6.7 million for the extension of presumptive compensation entitlements for CFS volunteers who contract certain cancers

$6.7 million for the extension of presumptive compensation entitlements for CFS volunteers who contract certain cancers $6 million for extra training and support for CFS, SES and Volunteer Marine Rescue, a new emergency services telecommunications system, two new CFS bulk water carriers and extra protective clothing for CFS volunteers

Family First MLC Robert Brokenshire said the Government was treading on thin ice.

"We've already seen the anger created when the Government increased the levy by $90 million last year," he said.

"What people are saying to me is, they want emergency services funded properly, but they keep questioning what the Government is doing with the massive amount of money they get every year.

"I think the Government would be treading on thin ice if they were to hit farmers again with an ESL increase.

"It may well be some of the farmers carry out their threat and don't continue to be members of the CFS."

Mr Brokenshire said the $90 million raised by the ESL hike last year went to Treasury and was not spent on emergency services.

Sampson Flat bushfire response just under $10 million

Emergency Services Minister Tony Piccolo said the Sampson Flat bushfires of January cost the state's emergency response budget just under $10 million.

This included about $6.6 million for CFS operations, $2.4 million to the Department of Planning, Transport and Infrastructure, $600,000 to the Department of Environment, Water and Natural Resources, $250,000 to the MFS and $65,000 to the SES.

Mr Piccolo said in any budget there was a "revenue side and an expenditure side".

"If the expenditure goes up, you need to find revenue," he said.

"Unless you find savings elsewhere, that remains the case with any budget."

The state budget is expected to be announced in mid-June.
