[citation needed] The companies imported and installed fibrous, loose-fill amphibole asbestos, in most cases brown amosite from South Africa, although blue crocidolite has been detected.

The loose-fill amosite asbestos used by Mr Fluffy was especially hazardous, because its lack of a bonding agent allowed it to migrate easily to hidden corners and cracks inside a residence.

[3] In 2015, the Government of the Australian Capital Territory released a list of places affected by Mr Fluffy insulation contamination, which totalled 1,022 properties.

[citation needed] Dirk Jansen ran his company from his family home in Lyons and stored bags of asbestos fluff under his house.

[citation needed] Prompted by growing public concern about the hazards of asbestos in general, and Mr Fluffy's product in particular, a Commonwealth audit in 1988 identified most of the homes in the ACT containing the insulation.

[8] A number of heritage homes have also been affected and will be lost, including Deasland, one of Canberra's most important historic homesteads, which was built by George Harcourt in 1893 and was demolished in early 2022.
