U.K.-based travel management company ATPI has acquired Sydney-based The Travel Authority, expanding its footprint across Australia and New Zealand, the company announced.

Financial terms of the deal were undisclosed. 

The acquisition gives ATPI a portfolio that includes “a raft of established corporate travel clients” and its largest office presence to date in Sydney, the TMC said. The Travel Authority also has operations in Perth and on the northern coast of New South Wales, including clients in the marine and energy industries, which is a focus for ATPI, and in events and leisure travel.

“ATPI’s dedicated marine and energy, and mining and resources, divisions are growing in Australia, and the acquisition of The Travel Authority cements our expansion in this region,” according to ATPI Group CEO Ian Sinderson. “With a strong corporate presence in Sydney and the servicing of marine customers in Perth, The Travel Authority team complements our existing Melbourne- and Perth-based operations, as well as bringing additional support and expertise to our team.”

ATPI significantly has grown its global footprint over the past few years, including the acquisition of German TMC Hamburg Süd Reiseagentur last year.

ATPI on Tuesday also announced that it has added new leaders to its group sales team. Nikki Regan, a former ATPI executive who more recently had been director of traveler care in the U.K. for American Express Global Business Travel, is rejoining the TMC as head of group commercial strategy in the United Kingdom. Former ATPI executive Julian Mills also is returning as the TMC’s director of corporate sales.

In addition, ATPI has promoted head of corporate, media and sports sales James Draper to U.K. sales director.
