The federal government sought the extradition of nine people, seven of which related to child sex offences, to Australia in the past financial year.
One person was returned to Australia to face murder charges and another for drug offences, the annual report of the attorney-general's department said.
There were 34 unresolved extradition requests made by the Australian government at the end of the reporting period.
Australia also surrendered 10 people during the same time period to the United States, United Kingdom, Ireland and Poland for crimes including sexual assault, manslaughter, child sex offences and fraud.
This included four Australian citizens, two of whom were convicted.
Of the remaining two, one had pleaded guilty and was awaiting sentencing and one was awaiting trial as at the end of June 2021.
