January in Sydney has several cultural stalwarts that offer it’s sun-drenched denizens ways to get together and part-ay, none as long-running and culturally ingrained as the free, live shows in the Domain, put together as part of the yearly Sydney Festival.

Many a Sydney-sider has chucked the picnic blanket over the shoulder and strolled into the Domain, bottle of vino and hamper brimming with cheeses in hand, for a balmy evening of Jazz, Opera, Rock or even Spanish Flamenco over the years but this year’s offerings differ in a number of ways, namely that for the first time in its history Sydney Festival is banning BYO alcohol and food.

Yep, for this Saturday’s Flaming Lips headlined free gig in The Domain, patrons will not be allowed to bring their own food and beverages, instead being forced to purchase from the on-site bar and food facilities.

The gig, which kicks off at 5pm and also hosts sets from Royal Headache and Belfast FM, is the first time that the January Domain series of gigs will be no BYO. The following weekend shows of Opera in the Domain and Symphony in the Domain remain BYO friendly.

Confirming the ban to us via Twitter, Sydney Festival says the rule is due to ” limited space” as well as the fact that bands are playing right from gates open at 5pm. “Also security reasons and keeping the event free from dangerous substances & items.”

The BYO ban is most likely being enforced due to the nature of the gig, which unlike in previous editions, is a more raucous all-out rock gig as opposed to a sit on a picnic rug and chill vibe, as well as the fact organisers are probably expecting larger numbers than in prior years.

You’ve been warned friends, bring those cash moneys if you’re heading along this weekend.

Check below for the full list of prohibited items, as noted on the official Sydney Festival website and head to our SydFest Feed here, for the full list of shows including gigs by Girlpool and Joanna Newsom.
