The first 'baby boxes' have been introduced in the US state of Indiana so mothers can leave unwanted babies in safety.

The commitment from the US to the scheme comes just three months after NSW Deputy State Coroner Hugh Dillon made a recommendation for baby drop-off boxes following the inquest into the death of a child, whose remains were found at a Sydney beach.

Authorities were unable to conclude who the baby dubbed Baby Lily Grace was or how she died. Mr Dillon called the death "mysterious, distressing and confronting".

The Knights of Columbus, the world's largest Catholic fraternal organisation, is funding the first 100 baby box installations in Indiana, reports NY Daily News.

One baby box can cost between $2000 and $4000.

The 'Safe Haven Baby Boxes' are padded and lock from the outside and also have a sensor alerting authorities as soon as the door is opened.

Save Haven Baby Boxes founder Monica Kelsey, a volunteer firefighter and medic, said: "If these boxes are the answer, great, we're trying to come at it from all angles.
