The Government says there is every chance prisoners will soon be able to keep in contact with people by video call.
The wide use of video-calling in Australia's justice sector was recently observed by Courts Minister Chester Borrows.
He says the contact helps inmates maintain family links and reduces the likelihood of re-offending, while also being cost-effective and safe.
Corrections Minister Anne Tolley says her officials are already investigating the introduction of video-calling.
But she says until a trial of the scheme takes place, the costs remain unclear.
Mrs Tolley also says she does not know if video-call visits would be made available for all inmates or just those with family and friends at a distance.
