Woolworths Group is reporting an annual 21 percent decline in earnings - before interest and taxes - to 249 million dollars

Sales went up 4.6 percent.

Managing Director, Spencer Sonn, says as a business - they've faced the same cost challenges as customers.

He says high global inflation, ongoing supply chain issues and bad weather have all materially impacted the business.

Sonn says despite that, they've given workers an average 19 percent wage increase over 2 years.
