The announcement is a rare digital content first for Australian users. For a $3.00 per month subscription fee subscribers will get access to ‘all you can eat' downloads.

The downside is that although the MP3.com.au music catalogue numbers in the 100,000 tracks, these are from independent artists rather than the higher profile songs in other catalogues.

MP3.com.au features 15,000 Australian and 10,000 international artists.

The downloads will be converted into the mobile music standard format mpg4.

"This is the first time in Australia that a mobile network is able to offer such a service," said Domenic Carosa, destra's CEO. "3 mobile is adding genuine value to its customer base by making available and simplifying unlimited downloads of high quality digital music to mobile handsets."

"Working with destra to deliver MP3.com.au on 3 mobile gives our customers access to unsigned, talented music recording artists," said Annie Mackin, 3 mobile's Head of Content. "The subscription service allows our customers to download as many tracks as they want from mp3.com.au's extensive catalogue of songs as often as they want each month."

destra Media is hosting and managing the service and has developed the user interface and experience for 3 mobile customers.
