Gyprock is an Australian manufacturer of gypsum-based products. They do not intentionally include asbestos in any of their products.
It is possible that spun wool insulation manufactured in the 1940s could contain asbestos.

It is recommended to have the insulation tested for asbestos before conducting any renovations or other activities that could disturb the material.
No. Rock wool is made from rock that has been melted and then forced through small holes to make long, fibrous strands. It does not contain any asbestos. Even if the rock used in the beginning did contain asbestos (and that kind of rock is not used for this) the asbestos fibers would be melted and destroyed in the manufacturing process.
No. Rockwool or mineral wool insulation is mineral fibers from volcanic rock heated and spun into a cotton candy texture and has never been reported to have been manufactured using asbestos.
It is possible that a brand of Johns Manville Spintex rock wool insulation from the 1950s may contain asbestos. Asbestos was commonly used in insulation materials during that time period.
