Coopers Brewery Ltd has reported a leap in its annual net profits, off the back of rising sales.

The independent brewer, which is battling for survival following a hostile takeover offer from Lion Nathan, said that net profits jumped by 51% to A$14.3m in the year to 3 June.

Coopers' sales growth drove the good results, with sales value up by 18% to A$127.2m, and volumes also up 18% to close to 50m litres.

The sales growth was pushed by sales outside of Coopers' home state of South Australia.

Coopers said its interstate beer sales have increased by 72% over the past two financial years.

The company said it will pay a final dividend of A$3 per share, up from A$1.05 a year earlier.
