This is the best summary I could come up with:

For several hours the home in Arncliffe was cordoned off with tape warning of a toxic, nuclear or biological hazard inside.

Australian Border Force (ABF) confirmed officials had carried out an operation with the assistance of fire crews.

The material was discovered in a suitable and effective container with no release of radiation, the brigade added in a statement.

Photos from the scene showed the small brown-brick apartment building cut off from the road by red and yellow tape saying: “Contaminated area - do not enter - hot zone”.

Nemr Khamis, 60, added: "In the morning I heard the loud trucks and all that stuff, I looked out of the window and I saw the ambulance and the fire brigade.

Part of Australia’s department of home affairs, the AFB is responsible for offshore and onshore border enforcement, investigations, compliance, detention operations as well as customs services in the country.

I’m a bot and I’m open source!
