How much does it cost for two people to travel to Australia 10 days?

Go to Australia with Zhongxin Tourism Group, 1 1 day. The tour fee is 1.5w for one person. There are quite a lot of places to visit, such as Cairns, Sydney and Melbourne, and the hotels are also very good ~ if you go alone, you want to have a good time of 25,000 to 30,000 RMB. If I play the Great Barrier Reef and seaplanes or helicopters, Australia is not cheap! If it is a poor tour, the budget is about 1000 yuan per person per day plus round-trip air tickets ~
