Samoa A handed Queensland their first defeat to finish the Australian leg of the Pacific Rugby Cup with it's perfect record in tact.
Last season's runners-up were 24-8 winners in Brisbane on Monday, following victories over the Brumby Runners and Junior Waratahs.
Fiji Warriors made it back to back wins with a 30-15 defeat of the Junior Waratahs in Sydney.
Both teams now head to New Zealand for the next three rounds, with the Tongan team already in Auckland.
