Dangerous sexual predators will spend a year in jail in Qld if they try to remove their GPS tracking devices.

Dangerous sex offenders who tamper with their tracking devices will spend at least a year in jail under new reforms in Queensland.

Offenders who procure a child or a person with a mental impairment for prostitution also face up to 20 years in jail, up from the current maximum of 14 years.

The reforms are part of the Queensland government’s sweeping changes to dangerous sex offender laws, which are due to be introduced before the middle of the year.

Attorney-General Jarrod Bleijie says offenders who try to remove their GPS tacking devices will spend at least one year, and up to five years, in jail.

“There is a high proportion who re-offend,” he said.

“We want to make sure they see these laws as a deterrent.”

Since 2011, five offenders have tampered with or removed their tracking devices, including two escapees in 2013.

Algana Amos James Tiers, 26, and Tyrone Speechly, 25, fled from corrective services accommodation in Townsville after cutting off their GPS tracking devices in April.

Mr Bleijie said the child protection group BraveHearts supported his latest reforms.

The government has recently been criticised for introducing contentious laws without wider input from the judiciary or civil libertarians.

It backfired late last year when laws that gave Mr Bleijie the power to jail dangerous sex offenders indefinitely were found to be invalid, sparking the current review.

Opposition Leader Annastacia Palaszczuk says the Newman government must commit to full consultation and scrutiny of its planned changes.

“We need workable laws that protect the community and that stand up in court,” Ms Palaszczuk said.

“The know-it-all Attorney-General Jarrod Bleijie bungled his first attempt to change sex offender laws by refusing to subject them to scrutiny and public hearings by the state parliamentary committee and refusing to talk to the legal fraternity.”
