SYDNEY, June 17, 2016 (Xinhua) -- Photo taken on May 25, 2016 with a cellphone shows Chinese tourists shopping at a Duty Free store in Sydney, Australia. Kickbacks to Australian tour guides are still continuing despite a raft of measures by local authorities to counter the practice, causing Chinese tourists to pay up to three times more than the average cost of some goods.
