Prisoners are being rewarded with sex for good behaviour as authorities believe it helps them reintegrate into family life.

An extension of the visit centre hosts the inmates and their guest in a special room which is available to low and medium security offenders across Victoria and the ACT only.

Corrections Victoria spokeswoman Courtney Crane wouldn't give details about how the approval process or how many conjugal visits took place but said it helps the prisoners reintegrate into family life once they are released.

'The program has been significantly strengthened in recent years, with special-category offenders subject to a much higher threshold of approval,' she told the Herald Sun.

The special relationship must be approved and evidence must be given they were together before the inmate went inside.

One senior corrections source said some inmates were successfully faking their status to get someone approved.

For some legitimate, model inmates it was a chance to be rewarded.

'You know the ones who get approved have played ball and have been good during their sentence,' the insider said.

Corrections Victoria said the Residential Visit Program also offers contact with children and opportunities to see other family members.

The initiative aims to reduce reoffending while also minimising the 'heavy' impact on loved ones.
