The Australian Competition and Consumer Commission are urging households to check if they had faulty Infinity electrical cables installed between 2010 and 2013.
According to reports, the cables can cause house fires and electrocution.
The product safety regulator said Infinity cables installed in NSW homes in 2010 could have already started cracking, but other states and territories (where it was installed from 2011) could be in danger from next year.
"If you have had electrical cables installed in your home between 2010 and 2013, the ACCC is urging you to get your home inspected by a licensed electrician. Do not attempt to inspect the cabling yourself,” ACCC Deputy Chair Delia Rickard said.
The cable could become prematurely brittle and break when near heat sources and roof access areas if the cables are disturbed by home owners or tradespeople.
The national recall began in August 2013, however four years into the recall, only 54 per cent of the 4,313 km cable has been fixed.
Ms Richard said suppliers, installers and property owners are affected.
"In some circumstances, suppliers, installers and property owners may be liable to pay compensation for injury or property damage caused by Infinity cable installed in building,” she said.
All TPS and Orange Round cable sourced from Infinity Cable Co Pty Ltd and supplied under 'INFINITY' and 'OLSENT' brands are affected.
