Bushfire affected Kangaroo Island residents can now access $280 per adult and up to $700 for a family to help with their immediate needs.
Assistance is being provided through the jointly funded Commonwealth-State Disaster Recovery Funding Arrangements.
Minister for Natural Disaster and Emergency Management David Littleproud said this support would put cash in the pockets of those most in need.
"These hardship payments are to help meet immediate needs such as food, clothing and medicine," Minister Littleproud said.
"These emergency relief payments will put cash in the pockets of those most in need and help give them dignity.
"This assistance is in addition to the recovery support already available to the Kangaroo Island community.
"The Commonwealth will continue to work closely with the South Australian Government to ensure bushfire affected communities can recover."
South Australian Minister for Human Services, Michelle Lensink, urged residents directly affected by the Kangaroo Island bushfire to apply for the one-off emergency government grants to assist with immediate, temporary relief.
"In difficult and trying times like these, the community needs assistance quickly and efficiently – and we are here to help," said Minister Lensink.
"Residents directly affected by the Kangaroo Island bushfire can receive up to $700 per family.
"The emergency relief grants are intended to provide immediate financial help for essentials, such as toiletries, medication and clothing and I urge affected residents to apply for this relief.
"The State and Federal Governments are standing shoulder to the shoulder with the community at this tough time and further recovery will be made available as required."
Minister Lensink thanked volunteers and emergency services on the ground.
"It is thanks to the vital work of volunteers and emergency services right across the state that our communities have people there to help in their hour of need – thank you," Minister Lensink said.
