The family of a Sydney schoolboy killed in the Barcelona terror attack, and several others who were hurt, will be offered $75,000 in support.
The federal government on Tuesday formally declared the incident an act of terrorism to allow those affected to receive one-off payments.
Seven-year-old Julian Cadman was among more than a dozen people who died after a van mowed down people in the market area on Las Ramblas on August 17.
Another seven Australians were affected, including his mother Jumarie who was injured.
The declaration means that Australian residents harmed, or whose close family died, as a direct result of a terrorist attack, can seek or share in a payment of up to $75,000 in financial assistance.
The Australian government has now declared a total of 40 overseas terrorist acts, including the Barcelona incident and another in Cambrils, Spain, a day later in which a vehicle drove into pedestrians.
"It is an important acknowledgement of their pain and suffering," Attorney-General George Brandis and Human Services Minister Alan Tudge said in a joint statement.
