Plug pulled on expo deal THE NSW government's decision to terminate arrangements with a consortium to build a temporary convention facility while Sydney's Darling Harbour undergoes a $1 billion revamp has alarmed the multi-million-dollar events sector. Negotiations between a consortium known as Sydney Harbour Expo@Glebe Island - which won preferred bidder status to construct 25,000sq m of temporary exhibition space in December - and Infrastructure NSW were terminated on Tuesday night.
