For the fourth consecutive IRB Sevens World Series event the two South Sea island nations clashed in the final and, after their reverse in Hong Kong, the Fijians this time prevailed in front of over 13,000 passionate fans.
Unlike in Hong Kong, where the final saw a barrage of points scored either side of the break, the Adelaide decider was a tight affair and on this occasion the Fijians outfoxed Samoa.
Having seen them through to the final with mesmeric solo efforts at the death in both the Cup quarter and semi final, player of the tournament William Ryder sat on the bench for the first half, at the end of which the sides were locked at 7-7. With Samoa's warriors tiring in the second half, Fiji then turned to Ryder and shortly after replacing Serevi he jinxed through for Fiji's third try.
The Adelaide event was a resounding success and, with over 25,000 fans through the turnstiles over the two days, looks set to become a tournament to rival the best on the Series.
Defending Series champions Fiji now have 104 points, 10 clear of Samoa on 94 and 14 more than New Zealand going into the final two events in London and Edinburgh.
Earlier in the Cup, Kenya scored a shock victory over England to win through to their first ever IRB Sevens World Series semi final and although they lost to the Samoans they take 12 points from an IRB Sevens event for the first time.
In the other semi final New Zealand led Fiji for much of the game before the brilliant Ryder stole the show at the death.
Australia claim historic Plate
The magnificent Adelaide Oval crowd was treated to a home success when Glen Ella's Australia won a rare victory against the Boks of South Africa.
Anthony Sauer scored a hat trick and Ben Lucas and skipper Tim Atkinson each scored as the home side ran out 31-0 winners to take the plate trophy and eight points towards the IRB Sevens World Series race. South Africa receive six points for finishing runners-up.
Wales win Bowl
Two tries by Jamie Roberts and one each for Lee Williams and Jonathan Edwards were enough to see Wales to the Bowl title against Tonga, 26-14.
Remarkably the success was Wales' eighth trophy in as many events and they also overturned a large loss suffered at the hands of the Tongans in Hong Kong. Tonga's tries in the final were both scored by Vungakoto Lilo.
Canada take Shield title
Canada finished the Adelaide tournament on a high, beating Japan 43-17 to take the Shield title.
Leading 17-5 at the break following tries by Akio Tyler, Dave Moonlight and Neil Meechan, Shane Thompson's men cut loose in the second half to score four more to Japan's two. Philip Mack, Tyler, Moonlight and Ben Grant all scored for the Canucks while Yamamoto and Nakazono added to Suzuki's first half effort for Japan.
