Australian wine exports increased by 13.5% in the volume in the year to the end of April helping value to reach an annual A$2.5 billion (US$1.73 billion) up 5%.

The nation's Wine and Brandy Corporation said the lower value growth reflected a 7% decline in average value per litre.

Red table wine, bottled and bulk, drove growth and comprised three quarters of the additional 45 million litres of bottled still wine shipments.
