Now would be a good time to give up.
While the Australian governments gain lots of revenue from taxing tobacco products they are also trying to discourage smoking. This means that there is no advertising of tobacco products and smoking is banned in all public buildings, public transport, taxis, restaurants, etc. (some restaurants may have an exemption if they have a separate area for smokers).
Also note that all flights within and to Australia are non smoking and smoking is banned in all airline terminals.
