The Australian Recording Industry Association (ARIA) has honored 13 domestic acts at its ARIA Number One Chart Awards for reaching the top spot between Jan. 1 and Dec. 31 2007 on ARIA's weekly singles, album or music DVD charts. Australian artists notched up 29 weeks at the top across those charts last year.

At a ceremony held in Sydney's Doltone House venue today (March 6), Eleven/EMI rock band Silverchair collected awards marking its four weeks at No. 1 with the single "Straight Lines" and a similar spell at No. 1 on the albums chart with "Young Modern."

Singer-songwriter and "Australian Idol" winner Damien Leith was honored for a three week spell at No. 1 with "The Winner's Journey" album (Sony BMG) and one week with the single "Where We Land".

AC/DC's "Plug Me In" (Albert Music/Sony BMG) was another wnner, having spent five weeks atop the DVD charts.

John Parker, head of the ARIA chart and marketing committee, tells Billboard.biz: "[When launched] six years ago, the idea of these chart awards was to provide media publicity for the charts. Now it's all about the artists and their achievements."

Denis Handlin, ARIA chairman and chairman/CEO of Sony BMG Music Entertainment Australia told attendees, "The future of this business is not dependent on new technology, the internet or how smart the bean counters are. The future of our business is built on discovering new talent and supporting our artists."

Delta Goodrem and John Butler performed acoustically at the event, which also featured performances by two up-and-coming acts. They were rock band Getaway Plane (Shock), which debuted at No. 14 on ARIA's album chart late February with "Other Voices, Other Rooms," and singer/songwriter Michael Paynter, who will launch his debut single "Closer" in May through Sony BMG.

The awards were filmed by MTV Australia for a one-hour special.

John Watson, Sydney based manager of Silverchair and Missy Higgins says, "Such events are a reminder of how important local music is. It's interesting that the more global we get, the more important local music becomes. In Australia we're getting more and more local No. 1's; that's just an indication of how healthy the Australian music scene is."
