ACCC chairman Rod Sims said competition in the online travel booking sector had grown considerably recently, which would limit Expedia's ability to increase fees. "The ACCC considered that the acquisition was unlikely to diminish the dynamic nature of the industry," he said. He said a number of smaller online travel agents had entered the market and metasearch sites like Tripadvisor and Google Hotels Finder were playing an increasingly important role, allowing hotels to directly market themselves to consumers. "Disruptive developments from smaller online travel agents and from companies in related online sectors, such as the metasearch providers, can be expected to constrain Expedia in the future." Despite the ACCC's approval, the Accommodation Association of Australia and the Tourism Accommodation Association say their concerns remain. "Currently Expedia is estimated to hold 10 per cent of the Australian hotel portal market. With the acquisition of Wotif, Expedia will grow to 45 per cent. Another major competitor, Priceline, is believed to have approximately 40 per cent. With a successful acquisition the two companies may have up to 85 per cent of the Australian market," said industry spokesman Bradley Woods. "The acquisition may trigger major commission rate increases, flowing onto consumers and the Australia tourism industry. Higher commission rates are bad news for consumers."
