I didn't find it fair to talk about Marijuana in Australia without pointing out Australia's "Beer Culture". So I did something I've wanted to do personally for awhile now, determine exactly how much beer is produced in Australia. So I turned to Wikipedia...
The 'Breweries in Australia' Wikipedia article divides breweries into 3 categories.'Major Breweries', 'Microbreweries' and 'Brewpubs'.
'Major Breweries' currently consists of 9 breweries consisting of nationally recognizable beer brands.
'Microbreweries' are distinguished by adding that "The maximum amount of beer a brewery can produce and still be classed as a microbrewery varies by region and by authority, though is usually around 15,000 barrels (18,000 hectolitres/ 475,000 US gallons) a year."
There are a total of 114 Microbreweries listed in the article. I did note that one microbrewery was closed, so I am unsure how many are still active in the complete list (sorry, no. I won't be crecking them all individually :P)
Brewpubs; restaurants or pubs that have breweries attached to them...34 of them make the Wikipedia list.
157 recognised breweries in total...now for some figures.
Carlton & United Breweries
Producers of Victoria Bitter (VB), Carlton Draught, Melbourne Bitter, Carlton Cold, Carlton Midstrength, Carlton Black, Crown Lager...although I could only produce figures for how much Victoria Bitter (VB) that they produce.
"VB is Australia's only billion dollar retail beer brand and sells the equivalent of one slab (24x375ml cans/bottles (9 Litres) every second"
9L X 60secs X 60mins X 24hrs X 365days = 283,824,000 Litres per year
(http://en.wikipedia.org/wiki/Victoria_Bitter)
Cascade Brewery
36 million litres (http://en.wikipedia.org/wiki/Cascade_Brewery)
Coopers Brewery
"Production during 2010-11 reached a record 62.9 million litres"

Boag's Brewery
J. Boag and Son currently (2010) employes over 150 people and produces over 76,000,000 litres of beer annually.

Tooheys Brewery
Production output: 300 million litres

Providing these figures are true, between these 4 breweries and the most successful beer of just one other major brewery, a total of 758,724,000 litres are brewed! If Australia's population were to be 23 million (it's less) there would be enough beer produced to give everyone over 32 litres.
Thanks for reading :) To wrap things up here's a picture that illustrates what Australian's today think of our collective alcohol consumption...
