Chief Minister Andrew Barr said Floriade 2019 attracted 507,550 people through the gates across the month-long festival and NightFest.

That figure exceeds Floriade's previous 2014 record of 481,854 people, he said.

This year's attendance represented an increase of over 27,000 people from last year's event of 480,540 attendees.

"The ACT government is committed to delivering a world-class event which achieves increased visitation and strong economic return as well as providing an outstanding visitor experience." Mr Barr said.

"This year there was a continued focus on the event layout, including a change in market stall locations, more seating around Commonwealth Park and more entertainment across multiple stages and venues.

"With its focus on attracting interstate and international visitors, Floriade showcased some of the best products from our region with Pialligo Estate, Capital Brewing Co., Contentious Character and Underground Spirits joining a range of local food vendors and market stalls.

"Over four nights across the October long weekend NightFest delivered a jam-packed program that included big acts like The Veronicas, Mitch Tambo, Dave Hughes and Urzila Carlson plus local acts The Baker Boys and Los Chavos."

Preparations are already underway for Floriade 2020, which will return to Commonwealth Park from Saturday, September 12 to Sunday, October 11, 2020.
