Automatic warnings at high speeds and live electronic monitoring are just some measures used to ensure the safety of posties.
A submission to the parliamentary road safety inquiry examining how Australia can push toward no road deaths by 2050 outlines the mail provider's efforts to keep drivers out of crashes.
Key among the initiatives is Australia Post's use of telematics, with on-board computer equipment tracking location and speed - and even providing an audible alert when a driver exceeds 103 km/h.
Vehicle performance such as over-revving and harsh braking are also monitored, while the technology also generates automatic compliance reports that are sent to depots.
"Drivers play a key role in creating safer roads ... we believe that telematics is one of the most useful technologies to improving driver safety," the submission reads.
All Australia Post heavy vehicles have dash camera systems, automatically triggered by intense acceleration, braking and cornering.
The submission also describes Australia Post's future plans regarding road safety, which include using electronic work diaries to constantly manage driver fatigue levels.
It is also considering the use of advanced computer vision technology that would offer real-time monitoring of fatigue and distraction via a system tracking eye closure and head position.
Australia Post invested more than $300 million expanding its operation network in the 2019/20 financial year.
The committee is examining measures that can be taken to achieve "Vision Zero" by 2050, referring to eliminating crashes causing death or serious injury.
Australia Post will give evidence to the inquiry on Tuesday.
