The Serb, who collected his fourth Melbourne title and sixth career major with victory over Andy Murray on Sunday, just about catches his breath before leading his country into their World Group opener against Belgium.
However, the 113-year-old competition is not the powerful draw card it once was.
World number two Roger Federer, fourth-ranked David Ferrer as well as world number seven Juan Martin del Potro have opted not to turn out for Switzerland, Spain and Argentina respectively.
Murray's British team does not have a match while 11-time major winner Rafael Nadal also misses Spain's trip to Canada as he completes his recovery from the knee injury which has kept him off court for seven months.
Djokovic and ninth-ranked compatriot Janko Tipsarevic, who spearheaded Serbia's first Davis Cup title in 2010, should help their country prevail over Belgium in Charleroi. The home side's top player David Goffin is ranked only at 50.
"The Davis Cup title came in the right moment. I believe that feeling of sharing one of the biggest titles in our sport with my team for our country, in our country, was one of the best feelings I experienced as a player," said Djokovic, who skipped the tournament in 2012.
His absence last year was felt as Serbia were defeated in the quarter-finals by eventual champions Czech Republic.
Spain, winners three times in the last five years, and runners-up to the Czechs in 2012, travel to Vancouver without their three top players -- Nadal, Ferrer and Nicolas Almagro, who has a leg injury.
