Reporting periods for child sex offenders in Queensland will double while some will be subject to lifelong monitoring under laws the state government says are the toughest in Australia.
Repeat offenders will be subject to 20 years of monitoring and reporting to police under legislation to be introduced to parliament this week.
Reporting periods for first-time offenders will increase from five to 10 years, Police Minister Mark Ryan said on Tuesday.
"The most serious recidivist child sex offenders will be monitored for their entire lives," Mr Ryan told parliament.
"Any form of child abuse is deplorable, while child sexual abuse is especially sickening."
The announcement follows plans to expand Queensland police powers to inspect the digital devices of child sex offenders.
The legislation introduced to parliament last month will allow police to enter the residence of a reportable offender to undertake a digital device inspection.
"This will go a very long way to evening the playing field," Queensland Police acting chief superintendent Denzil Clark told reporters in October.
"At the moment our power of entry is in relation to confirming reportable offender's personal details."
