CARDIFF — Australia got its Rugby World Cup campaign off to an winning start with a 28-13 win against Fiji Wednesday but it will be frustrated it could not claim a fourth-try bonus point after dominating most of the match. Fiji, which lost to England last Friday, started brightly but became ragged in the face of some well-disciplined Australian mauling that carried David Pocock over the line twice, with Bernard Foley weighing in with a pair of penalties to ensure a comfortable 18-3 lead at the break. Sekope Kepu blasted through soon after the restart and it looked set for a big Wallaby win, but Fiji fought back well and scored a try through Ben Volavola as Australia lost its way. Attention in Pool A now switches to Saturday, when England and Wales, who both won their opening games, meet at Twickenham. Australia's next game is against Uruguay Sunday. Fiji next faces Wales in Cardiff in eight days' time. Scotland sees off Japan In Gloucester, Scotland started its campaign with a 45-10 win over giant-killer Japan Thursday as the Brave Blossoms failed to follow-up their stunning defeat of South Africa with another victory. All of Scotland's five tries came in the second half. John Hardie and Mark Bennett helped Scotland, 12-7 up at the break, pull away before Tommy Seymour's interception score after the hour sealed victory. Scotland center Bennett's second try 11 minutes from time secured the bonus point before fly-half Finn Russell marked his 23rd birthday with a try of his own. Scrum-half Greig Laidlaw kicked 20 points on his Gloucester home ground. — Agencies
