Blacktown police commander Mark Wright is leaving his post after a tenure marked by a reduction in crime and a focus on community engagement.
Superintendent Wright has been at the station for seven years, and in the top position for five.
He said he had been offered a wide-ranging leadership position.
"I believe the time is right to look for a new challenge and further diversify my career," he said.
"The new position is the commander, management and leadership development, education and training command."
"I will primarily operate from the Police Leadership Centre on the UWS campus at Richmond, but will be responsible for a number of units at Parramatta Police HQ and Goulburn Police Academy."
"It will be very different to any command position I have held previously. But after 32 years of operational policing, it will be an opportunity to use my experience to help benefit our future leaders."
Superintendent Wright thanked the hard-working police and staff at Blacktown local area command.
"I am confident that Blacktown is a stronger place and will continue to evolve with the on-going engagement of the young people and the diverse community that is Blacktown," he said.
"There is no doubt, that my time here has been the highlight of my career to date."
Superintendent Wright has received high praise from the community for his work starting the Comm4unity program to engage young people in Blacktown, and with the city's diverse ethic groups.
His work changing perceptions of youth and crime in Blacktown has been the subject of ABC 7.30, A Current Affair and Sydney Morning Herald features.
His tenure as superintendent has coincided with annual average decreases in most crime statistics.
Superintendent Wright's last day is Wednesday, September 25.
His new role starts on October 1.
