Sexual assault is on the rise, with the number of victims hitting a seven-year high of 23,000 last year.
And for one in six of those victims, investigations wrapped up with no offender proceeded against.
The latest crime figures from the Australian Bureau of Statistics on Thursday show the largest increases occurred in Tasmania (up 15 per cent) and Victoria (up 14 per cent).
Both the number of female and male victims were the highest since the Recorded Crime - Victims collection of data began in 2010.
There were almost 19,000 female victims and more than 4000 male.
