This is how the market looks in
Percentage adult smokers
The Australian Bureau of Statistics reported that in 2011-12 there were 2.8 million Australians aged 18 years and over who smoked daily.
LHP status (legality, availability etc)
Sales of e-cigarettes containing nicotine are banned outright. Nicotine is classified as a Class 5 poison in Australian law and sale of liquid nicotine is therefore highly restricted. Sales of e-cigarettes with no nicotine are currently technically legal, but the federal and some state and territory governments are considering further restrictions that could amount to outright bans in some cases. For more information on e-cigarette laws and regulations in Australia and elsewhere, this site provides some insight, although factasia.org cannot vouch for accuracy or currency.
As of April, 2015, tobacco products in stick form (predominantly cigarettes and cigars) not exceeding in weight 0.8 grams per stick actual tobacco content pay AU$0.47008 excise tax per stick. Other tobacco products, including nasal snuff, are rated at AU$587.62 per kilogram of tobacco content. On November 6, 2013, the Government imposed four 12.5% annual tobacco excise increases which commenced on 1 December 2013, followed by another hike on September 1, 2014. The remaining two increases will be applied on September 1, 2015 and September 1, 2016, respectively, a cumulative 60% increase over the four years. It is estimated that the average Australian smoker will pay over AU$25,000 on tobacco products over the four years of the program. To compare tax rates on a country by country basis, this WHO site, although somewhat out of date, provides some insight.
Price of a pack of 20 sticks
It is estimated that illicit cigarette sales grew to 13.2% of total consumption in 2013 (Oxford Economics).
Packaging and labelling requirements
Health warnings cover at least 75% of the front of most tobacco packaging, 90% of the back of cigarette packaging and 75% of the back of most other tobacco product packaging. Since December 1, 2012, all tobacco products sold, offered for sale, or otherwise supplied in Australia must be in plain packaging. (ref).
