Heads up, Sydney — it's almost that glorious time of the year when all your favourite burger shops join forces. Yep, the beloved Burgapalooza is back for 2019, taking over Parramatta's Prince Alfred Square Park for both lunch and dinner sessions on September 21 and 22.

This year's lineup sees local legends like Mister Gee, Down N' Out, BL Burgers and Black Bear BBQ dishing up one-off creations to tempt the masses, with plenty of meat-free options to boot. There'll be joined by some star talent from further afield, too, including Brisbane's Fat Belly Jacks (and its Nashville hot chicken burger), Newcastle's Newy Burger Co and Burger Hounds from Wahroonga.

You can make your burger even cheesier, by loading it up with cheese sauce from a free — yes, free — cheese fountain. Spice fans, on the other hand, can test their tastebuds over at a chilli eating competition.

A selection of Coopers brews and Fireball whisky cocktails will be on offer, too, while a lineup of DJs play hip hop, funk and soul throughout the day.

In between burgers, the fun continues with a Wipeout-style blow-up obstacle course, with winners scoring free burgers and Menulog vouchers.

Burgapalooza will run from midday–4pm and 5–9pm on Saturday, September 22, and Sunday, September 23.
