Reservations for everything from caravan parks to five-star hotels  started flooding in a year ago and hotel booking websites report  travellers coming from overseas, and more than 100 locations across  Australia, with a "huge increase" from Perth.
           The average nightly rate for a CBD hotel room during the  conference has risen to $500, compared to $150 for the weekend before,  according to wotif.com. Reservations for the booking website's 600 Melbourne properties have soared, with 80 per cent of city hotels already sold out.
           And Wotif product director Donna Rodios said prices were  still rising, forcing travellers out to the suburbs and as far as  Geelong and Torquay.
           "The outer northern, southern, eastern and western suburbs  are recording a combined [week-on-week] increase of more than 100 per  cent," she said.
