So now that Norton Rose, Allen & Overy, DLA Piper, and — just last month — Clifford Chance have all launched in Australia, how long before the next big international firm makes a move Down Under?

Perhaps awhile, judging from the swift reaction of the two Magic Circle firms who might be expected to follow rivals Allen & Overy, which launched in Australia at the beginning of 2010, and Clifford Chance, which last week announced plans to merge with two boutique firms: Sydney’s Chang, Pistilli & Simmons and Perth’s Cochrane Lishman Carson Luscombe.
