Danny Noppert, Damon Heta, Gabriel Clemens and John Henderson are amongst the debutants in the BetVictor World Cup of Darts at the Salzburgarena from November 6-8.
The 32-nation tournament sees two-player teams representing their nations, based initially on the top-ranked players on the PDC Order of Merit.
Noppert, the 2019 World Series of Darts Finals runner-up, will make his debut for the Netherlands alongside three-time champion Michael van Gerwen.
2019 Brisbane Darts Masters winner Heta, meanwhile, will make his first appearance for Australia alongside former finalist Simon Whitlock, with Kyle Anderson still back in his homeland.
Henderson has been confirmed as Robert Thornton's partner for reigning champions Scotland, while Clemens will partner Max Hopp for Germany as he makes his debut in the event.
England's Michael Smith and Rob Cross will be the top seeds as they seek to secure a fifth title for their country in the tenth staging of the event.
New world number two Gerwyn Price will be joined by Jonny Clayton in the Wales team which is seeded second, with the Netherlands side seeded third ahead of Northern Ireland's Daryl Gurney & Brendan Dolan.
World Matchplay champion Dimitri Van den Bergh partners former World Cup finalist Kim Huybrechts for Belgium, with Germany being the seventh seeds.
2019 finalists Ireland are the seventh seeds as the partnership of William O'Connor and Steve Lennon is rekindled, with host nation Austria - represented by Mensur Suljovic and Rowby-John Rodriguez - completing the seeded nations.
Chuck Puleo will be partnered by 2019 CDC Continental Cup winner Danny Lauby in the American team, with the left-hander set to make his debut after Darin Young withdrew for health reasons after being diagnosed with vertigo.
Bruno Rangel won a qualifier in Brazil to secure his spot alongside Diogo Portela, while Andrea Micheletti and Daniele Petri won the Italian qualifier to secure their World Cup returns.
Haupai Puha will travel from New Zealand to partner Germany-based Cody Harris as they look to build on their run to the 2019 quarter-finals.
World Championship qualifier Matt Campbell will make his World Cup debut alongside Jeff Smith in the Canadian team, and big-stage newcomer Carl Gabriel will partner Devon Petersen for South Africa.
The BetVictor World Cup of Darts will be televised on Sky Sports as well as through the PDC's international broadcast partners including RTL7 and DAZN, as well as for PDCTV Rest of the World Subscribers and at matchroom.live.
