What is the consumption level in Sydney? Is it expensive?

Sydney's tourist attractions or shopping centers have dense food streets. Eat a light meal or fish and chips with drinks, about 12- 15 Australian dollars per person, and 70 yuan RMB is about RMB. And the dinner such as steak in restaurants is generally 30-50 Australian dollars/person, which is about 200 yuan RMB/person. The food stalls around Chinatown are more economical and selective. Food and daily necessities in Australian supermarkets are relatively cheap. For example, drinks bought in restaurants cost 3 Australian dollars per can, while supermarkets only need 0.7 Australian dollars. For accommodation in downtown Sydney, except backpacking inn and youth hostel, it is generally difficult to find a hotel standard room below 100 Australian dollars per night. Brand-name cosmetics or luxury goods will be lower than domestic prices because of the tax rate.
