Widnes will face champions Parramatta and Cronulla Sharks first up in their qualifying pool at next month's World Sevens. The Vikings are representing Great Britain in Sydney and also using the tournament as part of their pre-season training camp in Australia.
As well as the Eels and the Sharks, coached by former Wigan boss Stuart Raper, Widnes will also come up against a qualifier in their pool A matches.
Wigan were the last British club to take part in the tournament and ended up as winners in 1992.
The event will see Aaron Moule make his Vikings debut and takes place in Sydney on 24 and 25 January, with qualifying games earlier in the week.
