Retiring two-time grand slam champion Lleyton Hewitt has been confirmed as Australia's Davis Cup captain.

Hewitt, who helped Australia break into this year's Davis Cup semi-finals for the first time since 2003, will take over from Wally Masur, who was interim captain after Pat Rafter quit the role earlier in the season.

Hewitt faces a delicate task managing Australia's stable of rising talents, which includes the combustible duo of Bernard Tomic and Nick Kyrgios, both of whom have strained relations with the sport's national governing body and the public.

"For me, it's about instilling my experience in these younger guys," the 34-year-old told reporters in Melbourne.

Hewitt's playing career draws to a close after the next Australian Open in January and he retires with two Davis Cup titles in 1999 and 2003 and the record as his country's most prolific singles winner in the team-based tournament.

His first tie in charge will be at home against the United States in March.
