The firm released a statement saying that more than 90 per cent of its partners voted in favour of integration but that a handful of partner did not wish to join a global law firm.

"We respect their decisions and they will leave as friends of the firm. We wish them well in their future plans," the statement read.

Thomsons Lawyers chief executive partner Adrian Tembel said the new Brisbane office, to open later this fiscal year, will assist the firm in achieving its $100 million revenue goal.

"My partners and I signed-off on a three-year strategic plan late last year. Our expansion into Brisbane will achieve a number of our key financial and geographic objectives," he said.
