The "Battle for City Hall" debate between Brisbane lord mayor Adrian Schrinner and Labor mayoral candidate Pat Condren two days before the election has been cancelled amid coronavirus fears.

The Queensland Media Club had expected about 300 people to attend its luncheon planned for Thursday, March 25.

In the wake of the growing COVID-19 pandemic, the Queensland Media Club luncheon has been cancelled.

"Refunds will be provided, and the club will begin processing these over the next few days," a statement read.

"We hope to see you all at a Queensland Media Club luncheon in the not too distant future."
