Smoking costs a bomb
Because the Australian government does not want its citizens to smoke, they have made it incredibly expensive to do so. Smokers currently pay a tax of USD$0.7 per cigarette, which is one of the world's highest tobacco taxes.
It's expected to rise as well; from September through 2020, the tax rate will rise by 12.5 percent, bringing the cost of a pack of cigarettes to roughly USD$40. It's also working, with Australia's adult smoking rate nearly halving since 1980. According to Deutsche Bank, the world's two most costly cities for purchasing a pack of cigarettes (with costs around USD$20) are Melbourne and Sydney. If you're coming to Australia and have a smoking habit, now is the time to quit.
However, it's up to you whether you smoke or not, but it's not a cheap habit in Australia. With regulations in place that makes a packet of cigarettes cost $40 (£22), you won't want to start smoking here unless you're willing to pay a big portion of your vacation budget. This is definitely one of the top things about Australia You Should Know before traveling to this country.
