Any eligible business customer with facilities of up to $10 million could now defer repayments of their business loans for six months, the bank said on Monday.

Loan interest would be capitalised into the existing loans.

The bank said the support for business and agribusiness customers followed the federal government business relief package announced on Monday.

"To qualify for the deferral, customers must also be no more than 90 days in arrears at the date of the application and confirm their business has been negatively impacted by COVID-19," the bank said.

"Business customers who operate as commercial property landlords will be required to provide assurance to the bank they will not take any action against their tenants for the non-payment of rent for the period of their repayment relief. "

Managing director Marnie Baker said: "With today's announcement, almost every business customer will be eligible to seek deferral of loan repayments, which, in conjunction with the range of other available measures, will provide many with options to manage the impact of COVID-19 over the coming months`"

"We continue to provide the necessary assistance to our customers to ensure they get through this unique and challenging time and we are providing them with tailored support based on their individual circumstances."

She said the new measures would provide respite in the immediate period, but more support would be needed for businesses to prepare for long-term recovery.
