The uneventful opening follows US markets closing higher after senate leaders agreed to revive talks to craft a fiscal relief package.

However, global investors may have lost hope. After trading closed, Treasury Secretary Steven Mnuchin asked the US Federal Reserve to return money earmarked under the March pandemic relief act for emergency lending to businesses, non-profits and local governments.

Meanwhile South Australia’s building and construction industry says it must be allowed to resume operations next week to protect the livelihoods of 70,000 workers and limit damage to the state economy.

Elsewhere in the building industry, Grocon has called in administrators after problems with its Barangaroo construction project in Sydney.

Chief executive Daniel Grollo said he is furious at the government agency Infrastructure NSW, which Grocon has been fighting in court over the Barangaroo precinct.

On the ASX, insurer IAG will raise up to $750 million through a share sale after a NSW court ruled insurers have to pay compensation to business customers affected by the pandemic.

IAG will set aside $865 million for the potential cost of pandemic claims.

This decision will mean an $805 million impact on full-year earnings.
