"I have no immediate plans once I have finished withSydney Sixers and will look at every possible avenue that is put in front ofme."
Cricket NSW boss David Gilbert said, "The remarkablesuccess of the Sydney Sixers in its short history is testament to Stuart'sability to build a winning team. He has made a smooth transition from player toadministrator and is well placed for the next phase of his career. Whilst it isdisappointing to lose a person of Stuart's calibre, I understand and respecthis decision and wish him the very best for the future."
