Troubled steelmaker Arrium is expected to provide an update on its Whyalla steelworks when its chief executive fronts a Senate committee hearing.
Andrew Roberts is scheduled to face the committee, which is hearing evidence about the future of Australia's steel industry, in Canberra on Wednesday.
The committee earlier visited Whyalla, where union representatives warned that uncertainty about the steelworks had prompted many local homeowners to sell up.
Arrium is also expected to come out of a trading halt on Wednesday after its banks knocked back a proposed bailout involving a private equity group.
The company, which is grappling with growing debt and low iron ore prices, has said it needs to find $60 million in savings to continue operating the Whyalla steelworks.
There are fears jobs at Arrium's mining operations in Whyalla could be under immediate threat after some workers voted not to take a pay cut to help the embattled company.
