The Wallabies’ dismal World Cup campaign blew its budget by $2.6 million, or some 10 per cent, as Rugby Australia splurged on travel spending and benefits for players.

Phil Waugh, chief executive of Rugby Australia, said a review into the unsuccessful campaign found poor culture and a lack of trust were the main reasons for the national team’s performance. He said the governing body had made personnel changes as a result of the cost blowout caused by executives who had spent money without approval.
