The Disaster Hub app will allow businesses to access checklists, financial assistance and other resources when disasters strike in Queensland.

Businesses will find "prepare, respond and recover" checklists, suggested communication messaging, how-to video animations, small business resilience case studies and links to access information and financial assistance.

It's hoped the free app will help small businesses get back on their feet sooner after a disaster.

Small Business Minister Di Farmer says the government sought feedback from small businesses, industry and local councils hit by the 2019 monsoon trough in the north and far north.

"We know that small businesses have done it tough through COVID, and in north Queensland small businesses have been doing it even tougher," she said in Townsville on Tuesday.

"Whether that's a natural disaster or whether it's something like a cyber security strike, you can immediately go to the app and you can find out what you need to do immediately to keep yourself and your employees safe."

Thuringowa MP Aaron Harper said the app would help small business owners in stressful times.

"Many small businesses often become overwhelmed not knowing how to best prepare their business ahead of a looming disaster or where to go for help afterwards," he said.

The app has downloadable resources that can be accessed during power outages.
