There are some required laws to observe when selling wine in New South Wales from your website.
All available to read here: http://www.olgr.nsw.gov.au/liquor_online_sales.asp
Quite important to follow the laws because there are fines and penalties.
A few key things that stand out to me as very important.
Over 18 Warning
On your website you must display the following notice: ‘It is against the law to sell or supply alcohol to, or to obtain alcohol on behalf of, a person under the age of 18 years.’ This notice needs to be prominently placed on your website – consider putting it on your home page as well as the actual page where online sales are made.
That doesn’t mean you have to block people who are under 18 from viewing the site.
Display your licence number
If you sell alcohol online, you must display your liquor licence number prominently on the website and in any relevant advertisement published in print or electronically. You can consider placing your liquor licence number on the home page and the page where online sales are made.
Collect DOB of buyer
In NSW, the legal drinking age is 18 years. At the time you make the first online sale, you must confirm that the buyer is at least 18 years of age.
Most shopping carts let you require the customer put in a date of birth, its often a default.
Delivery must specify to whom it is going
You must give written instructions to the person responsible for delivering the alcohol.
A person under the age of 18 years cannot accept delivery of alcohol sold online, by phone, fax or mail order.
There is a checklist at the end of the OGR website.
This topic was researched in March 2013, it’s possible the laws may change in the future so refer to the OGR website for the official rules at the time you are setting up your shopping cart.
