The beginning of a consultation process follows Expedia's $703 million takeover of Wotif last year, which resulted in a jump in commission rates at the major online travel agents to 15 per cent from 12 per cent previously. Global giants Expedia and Priceline, the owner of Booking.com, now control about 80 per cent of the market for online hotel bookings in Australia.

They also ensure the last free room at the hotel is part of the available inventory of the online travel agents.
