Matthew Ebden has missed out on selection for Australia's Davis Cup first-round clash with Germany next week, with Alex De Minaur named in the five-man team.
Australia's second-highest ranked player Matthew Ebden has been overlooked for next week's Davis Cup clash with Germany in Brisbane.
Nick Kyrgios will spearhead the hosts' World Group first-round tie with Jordan Thompson, John Millman, doubles specialist John Peers and Alex De Minaur named in a five-man team.
Ebden beat world No.16 John Isner at the Australian Open last week and world No.6 Marin Cilic at Kooyong earlier this month but that form was not enough to get him the nod over Sydney teenager De Minaur.
Instead the 30-year-old will join Alex Bolt as the team's hitting partners.
"We have named Alex De Minaur in the five-man team after an impressive couple of weeks on the tour," Australian Davis Cup captain Lleyton Hewitt said.
"He has worked hard and we are pleased to give him this opportunity."
Thanasi Kokkinakis was not considered after suffering a pectoral injury in his early exit at Melbourne Park.
World No.17 Kyrgios will carry the hopes in the singles, after another run into the second week of his home grand slam.
"Nick comes off a title win at Pat Rafter Arena and a fourth round appearance at the Aussie Open so we'll be looking to channel his experience when we return to Brisbane," Hewitt said.
"Brisbane is also home for Johnny Millman and both Jordan Thompson and John Peers have had success on that court in singles and doubles."
Pat Rafter Arena will host a Davis Cup tie for the fourth time with the opening singles on February 2.
