One of Australia's top police officers has proposed an app to record sexual consent between parties to combat climbing sexual assault figures. 

NSW Police Commissioner Mick Fuller said rising sexual assault figures need to be addressed through technology and education on consent.

"Whether the app floats or not, I think it's irrelevant... I think it's about understanding that this crime is on the increase … and we need to confront it whether that’s through technology or education and training or through other ideas," he said. 

"Intimate violence particularly against women is a real problem crime for us at the moment and we need to find a solution," he told ABC Sydney.

Recent figures from the Bureau of Crime Statistics and Research state reported sexual assaults rose by 10 percent in 2020 with a total of 15,000 women coming forward.

Sydney University Professor Catherine Lumby said the app proposal was 'naive' and misunderstands the circumstances that surround sexual assault.
