The country all-but confirmed their spot at the flagship tournament on June 30 when they thrashed Germany 66-15 in the first leg of their qualifier on home soil in Apia.

They rubber-stamped passage today in the second leg in Germany at the Fritz-Grunebaum-Sportpark in Heidelberg, winning 42-28.

Ahsee Tuala, Melani Matavao and Ed Fidow both scored two tries each for the Samoans as they wrapped up a 108-43 aggregate victory.

The Germans, always the underdogs in the tie, scored three tries of their own and will still have a chance of reaching Japan through the repechage tournament.

Samoa will go into Pool A at the World Cup with Ireland, Scotland, hosts Japan and Russia.

"Congratulations to Samoa on Rugby World Cup 2019 qualification and a place in Pool A," said Beaumont.

"Germany will be encouraged by a strong performance as they look ahead to November's repechage."

Only two spots remain left at the World Cup, which will be filled by the winners of the Africa Gold Cup and the winners of the repechage tournament.
