Cheap booze deals for Sydneysiders advertised on Facebook.

It’s sly grog for the 21st century. A Facebook page offering round-the-clock booze delivery in Sydney has piqued the interest of NSW liquor licensing authorities, who are threatening fines of $11,000 and a 12-month jail sentence.

The Blind Pig Sydney page recently went live on Facebook, offering free delivery of six packs of beer and bottles of wine for $15 a piece and bottles of vodka and whisky with mixers for $50.

Delivery in the inner west, eastern suburbs, north and south Sydney is free, according to the ad, and proof-of-age identification is required on delivery.
