Australia warned locals specially those residing in Victoria state of the escape from prison of two of its worst sex predators.

If not for the electronic monitoring bracelets that the two men are required to wear, authorities won't be able to know that 27-year-old Sean Andrew Carmody-Coyle and 26-year-old David Gregory Byrnes have escaped Corella Place just before midnight on Wednesday.

However, the electronic tracking bracelets only work within the facility. Corella Place is a transitional facility for sex offenders who have completed their prison sentences. Although both men have served their sentences, police still consider them potential nuisances to the community and its safety.

Mr Byrnes sexually assaulted a five-year-old boy inside a toilet cubicle at a shopping centre in 2004 when he was 18 years old.

Less information, meanwhile, is known about Mr Carmody-Coyle and his offense.

The men had "breached their court-ordered curfews and left the facility unaccompanied late last night," a Corrections Victoria spokesman confirmed.

"Both of these men have significant criminal histories and are considered violent sex offenders and are dangerous," acting Victoria Police Commander Neil Patterson has told Fairfax Radio, noting police are continuing an extensive search of the Ararat area for the men.

In May, Corrections Minister Edward O'Donohue announced the Corella Place residents would be the first to use GPS-enabled bracelets that could help law enforcement authorities track dangerous parolees and even those on sex-offender supervision orders as it tracks them wherever they are.

But they are scheduled to be introduced next month, July.

The existing electronic bracelets with Messrs Byrnes and Mr Carmody-Coyle use radio frequency technology but only when the offender is in a specific area. Outside the zone movements are untraceable.
