Survey data released by the NSW government showed just six out of 10 women who experienced the offensive behaviour reported the incidents, which included unwanted conversation, being asked personal and sexual questions and staring by the driver.
Service providers including Didi and Uber will be issued with new guidelines by the state's Point to Point Commissioner, including driver training regarding what constitutes offensive behaviour towards women.
But the NSW opposition said that was not enough action, renewing calls for a QR code system within taxis for a clearer record to support complaints.
The guidelines will require driver training on offensive and unacceptable behaviour while also empowering providers to act on identifying best practice incident management.
"Whether you are travelling around town in the daytime, or out enjoying our vibrant city at night, this initiative will help ensure that every passenger on every rideshare, taxi and hire vehicle journey feels safe and respected," Transport Minister John Graham said.
"I asked the commissioner as his top priority to continue to reinforce safety standards and develop a culture of accountability within the point to point transport industry, and am very pleased to support these new guidelines in line with that priority."
 Uber, Didi and the NSW Taxi Council all backed the guidelines.
"We believe consistent, industry-wide guidelines play an important role in helping women feel safer when they travel," Uber Australia and New Zealand safety head Nicole Ashton said.
"Ongoing collaboration between government, industry and women's safety experts will be critical to ensuring these efforts are effective."
The NSW Taxi Council has also supported the NSW opposition's proposal for a QR code system within taxis.
The code would be linked to the driver and the vehicle, providing real-time trip verification, fare transparency and creating a clear record to support investigations into complaints.
"More than one in four women experiencing inappropriate conduct is a disgrace, and the government's response is far too weak, it is all talk and no accountability," Opposition MP Natalie Ward said.
"Government can't be in every cab, every time - but a QR code can. Training modules won't stop bad behaviour in the moment (but) real accountability will."
