Samoa A have come from behind to record their first win of this year's Pacific Rugby Cup on Tuesday.
Tonga A led 10-5 at half-time but the Samoans crossed for three second half tries to take the game 27-18 in Sydney.
Both teams now travel to Canberra where Tonga will face the Brumbies A team on Sunday and Samoa take on the Argentina Pampas XV next week.
