Saturday's four World Cup matches ended with an aggregate score of 264-10, renewing questions about the gulf between competing nations.
Samoa scored 50 second-half points to beat Papua New Guinea 64-6 in Port Moresby, after leading 14-6 at half-time.
England, needing points after losing to Tonga the previous week, defeated France 82-0 in Perth.
In the women's tournament, Fiji beat Papua New Guinea 40-4, before Australia's Jillaroos routed England 78-0.
England coach Stuart Barrow said his side had faced one of the world's most dominant teams.
"Listen, we got blown away by an excellent team - a team I think that's probably one of the best in the world across all sports at the moment," Barrow said. "They're dominant."
The results prompted fans to debate whether the World Cup format should better reflect differences in team strength, or whether Tier 3 nations need more support to improve.
The blowouts followed Lebanon coach Michael Cheika's claim a day earlier that his nation had been denied a warm-up game.
Separately, England player Jodie Cunningham drew criticism after taking the field in a replacement jersey with "14" written on its back.
She had changed shirts after blood got on her original jersey, but England appeared not to have another one bearing her number.
Fans said the handwritten number looked unprofessional and highlighted disparities between nations and organisations at the Rugby League World Cup.
