Australian bomb experts were working to destroy "explosive" materials found in a suburban Adelaide home Tuesday, following the arrest of a 43-year-old man.

South Australian police said the materials were found late Monday and the man, Aaron Ellis, appeared in court early Tuesday facing charges of possession of explosives.

"Investigations are continuing at the address," the police said in a statement, adding that the Bomb Response Unit had been deployed. "There is no danger or threat to the public," they said.

National broadcaster ABC said the man had come to the attention of the authorities earlier this year for anti-Muslim social media posts.

Local media reported the explosives were so-called Mother of Satan -- a chemical explosive used by jihadi and other terror groups.

Aerial images from the scene showed explosives experts packing sandbags around an object ahead of the planned controlled detonation.
