Julia Gillard, PM has concealed the insulation program and that has been taken well by the families of the victims.

The mess started when the Auditor General exposed a line of failings by the public servants and many other cases of fraud that have appeared after an expensive clean-up bill came up.

However, the PM has rejected to follow the Opposition's call that is asking for a judicial inquiry to be imposed on former environment minister Peter Garrett as well as on the scheme.

Meanwhile, the auditor’s report was submitted by the Auditor-General Ian McPhee in which he had scrapped months back the insulation scheme that had linked four deaths and close to 200 house fires.

As part of this, as many as 1.1million roofs had been insulated under the program which spent close to $2.8 billion as funds. It is now budgeted that it would need $500 million to be able to fix the problem.

In a research done it was shown that 29 per cent of the 13,808 roofs that had been inspected were suffering from some kind of deficiency.
