The Waratahs will delay seeking a replacement for sacked star Lote Tuqiri, with the international wingers camp "incredibly confident" of winning an unfair dismissal case against the Australian Rugby Union.

Tuqiri's sacking last week for allegedly breaching team protocol is still shrouded in mystery, with the Wallabies highest paid star launching immediate legal action to have his $1.2 million a year contract reinstated.

A court date is yet to be set but a source close to the rugby league convert Tuqiri's lawyers have compiled their case and were extremely confident of victory against John O'Neil and the ARU.

Tuqiri already has the support of Waratahs and Wallabies teammates, including captain Stirling Mortlock and the Rugby Union Players Association.

Former West Harbour president Geoff Moxham, who was instrumental in getting Tuqiri involved with the club, hoped the winger's appeal against his sacking was successful, saying the advantages far outweighed any adverse effects on the ARU.
