Australia's biggest businesses are being called on to offer victim-survivors of domestic violence more support.
The plea is part of a new corporate alliance, One Generation, which launched on Wednesday and aims to prompt business solutions for customers impacted by domestic and family violence.
Telco giant Optus has already signed up along with AGL and EnergyAustralia, Origin Energy, South East Water and Suncorp in a bid to provide better support within their services.
This includes staff training and re-training, account security, financial hardship relief and referrals to specialist services for customers.
One Generation co-founder Catherine Fitzpatrick said the alliance's inaugural companies have services that impact or are used by the majority of Australians.
"There is a really critical role for businesses to play here...as they may be the first place a victim-survivor asks for help," she told AAP.
"We have now got energy, water, telecommunications and insurance involved in this initiative because things are getting worse."
Chief executive at Origin Energy Frank Calabria agreed, saying essential services are often victim-survivors' "first line of defence".
Former Australian of the Year and advocate against family violence, Rosie Batty, said the initiative for businesses was long overdue.
"It takes all of us to contribute and create change. Use your power. Use your influence. Be part of the solution," she said.
"Because it will take every single one of us to stop this horrendous social issue in one generation.
"People experiencing domestic and family violence are in every element of our society. It does not discriminate, we all need to be part of this solution."
In 2016, Ms Batty called for a national corporate alliance to take action to address gender inequality and violence against women and their children.
The commitment comes after National Australia Bank was sued for allegedly failing to properly answer requests for hardship support from some of its most vulnerable customers over a near five-year period.
A lawsuit filed by the financial regulator in the Federal Court claims the bank and one of its subsidiaries did not respond to 345 hardship applications from customers within the 21-day period required by law.
The Australian Securities and Investments Commission revealed on Monday it was seeking the court to impose fines on NAB and subsidiary AFSH Nominees.
