Hotels Doubletree to make Australia debut via conversions By Danny King / February 11, 2013 Share 1 -- Australia will get its first three DoubleTree by Hilton hotels in May after Hilton Worldwide reached an agreement to reflag and manage hotels owned by BG Group of Hotels. Hilton will reflag all three hotels in Australia’s Northern Territory — two in Darwin and one in Alice Springs. The company will also reflag an additional Darwin hotel under Hilton’s flagship brand. The four hotels total more than 850 rooms. Hilton Worldwide already has nine Hilton-branded hotels in Australia, including two in Melbourne and two on Australia’s Gold Coast.
