Zambrero is aiming to pack one million meals on Plate 4 Plate Day in 2026, supporting communities experiencing food insecurity worldwide.
The event will take place on Thursday, October 15, with Sharks staff joining volunteers at Sydney's Carriageworks.
The club has participated since 2022, continuing a partnership that allows its people to support communities beyond the field.
Additional packing venues will operate in Canberra, Melbourne, Adelaide, Perth, the Gold Coast, Townsville and Hobart.
Zambrero's international hunger-relief partner, Rise Against Hunger, will distribute the nutritious meal packs to communities around the world.
Founded by Zambrero founder Dr Sam Prince, Plate 4 Plate has delivered more than 100 million meals since it began.
Although this year's volunteer sessions are fully booked, Sharks supporters can still contribute through Zambrero restaurants.
Customers who buy a participating burrito, bowl or Kids Zam meal on October 15 will support the campaign, with donations doubled across more than 350 restaurants.
Further information is available on the Zambrero website.
