After 18 years of planning, the new Sydney Theatre opens. “Snuggled into one of Sydney’s most artificial topographies is a new house of artifice. Its facade, dominated by that huge romanesque proscenium, declares up front a commitment to reality remade. Yet, at the same time, Walsh Bay’s new Sydney Theatre, opening on Saturday, is profoundly shaped by intimacy. You can call it ironic. Or you can relax in the knowledge that probing this truth-illusion relationship is theatre’s core business.”
