Luke Saville will make his long-awaited Davis Cup debut for Australia this week, a decade after winning his second junior grand slam crown.

Try telling Luke Saville the Davis Cup no longer matters.

A one-time junior prodigy, 28-year-old Saville will finally make his long-awaited Cup debut in Australia's qualifying tie against Hungary this week in Sydney.

While Germany's world No.4 Alexander Zverev was among the stars to boycott last year's finals in Europe in protest of the famous competition's revamped format, Saville says he wouldn't miss Davis Cup for anything.

"There's such a rich tradition and history of Davis Cup here in Australia to finally get the number and to play alongside great mates and great players that I've idolised is really going to a great experience," Saville said.

"It's definitely the biggest highlight of my career so far."

A decade after adding the Australian Open junior crown to his Wimbledon boys' title, Saville is contending for a doubles berth against Hungary.

He made the Australian Open doubles final two years ago before all but clinching a Davis Cup debut with two wins at the ATP Cup partnering John Peers.

Saville said his heart was racing when he received the phone call from Australia captain Lleyton Hewitt confirming his selection three weeks ago.

"It was really just goosebumps and chills. I still get it now," Saville said after a practice session at Ken Rosewall Arena under the watchful eyes of Hewitt and legendary Cup coach Tony Roche.

"I've looked up to a lot of these guys, all my teammates, for many years. Making my debut is a dream come true.

"Just seeing Tony Roche here and him being on court and taking us through our paces is amazing.

"I'll do whatever it takes to get the win this weekend, whether that's playing or supporting.

"I'm just thrilled to be finally back in Australia and to get the chance to play Davis Cup."

Peers, a grand slam doubles champion and Olympic bronze medallist last year with Ash Barty, is almost certain to be one of Hewitt's doubles picks this week.

Saville is contending with newly-crowned Australian Open doubles champion Thanasi Kokkinakis, Aussie No.1 Alex de Minaur and fellow Sydneysider Alexei Popyrin for the second spot.

"We've got a great team and the whole team is ready and raring to go," Peers said.

The winners of Australia's tie with Hungary will advance to the World Group Finals in September.
