The group includes 26 leading senior constables, 20 senior constables, 14 sergeants, seven first constables, five senior sergeants and one ranked inspector or above.
They are waiting for a court hearing or for their case to be completed, which can take years.
A spokesperson for Victoria Police said the force would not be deterred from investigating complaints against officers, regardless of their rank, position or tenure.
“No one in Victoria Police is above the law.
“The authority and responsibility entrusted in police means they should be rightly held to a higher standard than the rest of the community both on and off duty.”
The spokesperson said some officers facing charges resign before their cases get to court. Disciplinary action can start only once cases are completed and can include dismissal, fines, a pay cut or a ban on promotion.
Of the 78 members currently facing charges, 15 have been suspended with pay, 16 transferred to other duties and 13 suspended without pay.
The remaining 34 have no interim action against them.
About 17,900 people work as police or public transport police in Victoria.
