Lebanon played only one Test between the 2022 and 2026 Rugby League World Cups, facing Italy in Sydney.
Head coach Michael Cheika has selected no players from Lebanon's domestic competition, relying instead on ancestry-qualified players backed by the Lebanese diaspora in Australia.
The Cedars' quarter-final finish in 2022 secured automatic qualification for 2026, but their match against France could be their last World Cup appearance for the foreseeable future.
In 2024, the International Rugby League downgraded Lebanon from full membership to affiliate status.
World Cup participation requires full membership, which depends on governance and domestic participation benchmarks for men's, women's and youth Rugby League.
IRL chair Troy Grant told AAP that conflict creates a difficult environment, though Lebanon's governance has improved and Australia-based supporters are helping.
Grant said the nation has lacked the playing time needed to maintain participation numbers, making full membership difficult.
He said the IRL is working with Lebanon individually, as it has with Ireland and Scotland, to help it retain full-member status and World Cup eligibility.
