Jimboomba Relay for Life teams will instead by invited to join forces with the Northern Gold Coast Relay for Life at Coomera from October 26-27, free of charge.
A Cancer Council spokesperson said the decision to cancel the event was not taken lightly.
"The cancellation has been made with the safety of all our participants in mind," the spokesperson said.
"As a thank you for the Jimboomba community's support, we would also like offer free registration for the 2020 Jimboomba Relay For Life."
Jimboomba's 39 teams have raised more than $47,000.
Relay for Life campaigner Fiona Strachan, who lost two sisters to cancer, said they would have been proud of the $1612 she raised.
As the face of the Jimboomba Relay for Life campaign, Ms Strachan said she was overwhelmed by the generosity of the community, family and friends for their support.
"Our best defence is early detection, but we have made amazing progress with treatments including targeted treatments and immunology which has improved life expectancy especially for stage four cancer patients," she said.
"This can't be done without raising the awareness, clinical trials and raising funds for research and support."
