Islamic State terrorist Khaled Sharrouf and his two sons have been killed in Syria, media reports say.
The ABC and The Australian reported government officials as confirming Sharrouf - who fled Australia in 2013 to join extremist forces - and his sons Abdullah, 12, and Zarqawi, 11, were killed in a coalition air strike while driving near Raqqa on August 11.
Photos of Sharrouf's corpse and the corpses of his sons had been seen by members of Australia's extremist community, the ABC reported.
If confirmed it would be the first known deaths of Australian children by a coalition air strike in the Syrian war.
In February, Sharrouf became the first Australian to be stripped of citizenship under new anti-terrorism laws.
He made headlines in 2014 when he posted a photograph of one of his sons holding the head of a Syrian government official.
Sharrouf went to Syria on his brother's passport just a year after completing a four-year jail term for plotting a high-level terrorist attack in Australia.
He was caught during a major counter-terrorism investigation that broke up jihadist cells in Melbourne and Sydney.
