Woolworths has overcome tough trading conditions in the retail sector to lift its sales by 4.7 per cent to $56.7 billion in the 2012 financial year.
The retailer's key Australian food and liquor division increased sales by 3.8 per cent to $37.5 billion, while home improvement sales leapt 24.7 per cent and petrol sales rose 11.4 per cent.
Chief executive Grant O'Brien said the overall result was underpinned by growth in customer numbers, market share and units sold.
"The last quarter, in particular, was a stronger end to what was a challenging year," he said in a statement on Monday.
"Retail conditions remained subdued due to consumer and business uncertainty and an unseasonably cold and wet summer period."
