From the Crikey grapevine, the latest tips and rumours …

BAE builds fences. Eight companies have been contracted to build the new fence around Parliament House, and it seems the government is going all out on it. BAE Systems Australia, Lend Lease, Clayton Utz and Sparke Helmore Lawyers are among the companies picked to build what is expected to be a "thermal fence" around the front of Parliament. It's not quite clear what a company normally associated with building missiles and other defence gear will do in building a fence, as much of the detail around the construction of the fence remains a secret in order to protect it from "vulnerabilities".
