It is hard to fathom what it must be like to be the family and loved ones of a missing person.
Each year in Australia there are more than 38,000 missing person reports submitted to the police.
Despite more than 98 per cent of people reported missing are located there are those who are not.
In Tasmania, there are several outstanding missing person cases, some of which are high-profile, and some which are less so.
The theme of this year's National Missing Persons Week is Individuals, not Statistics and it gets to the heart of the matter clearly - every missing person matters.
Each of those people had families and loved ones who cared about them and who have never given up hope or the determination to find out what happened to them.
Tasmania Police do a stellar job working with those families to help provide closure where they can but when people go missing, often without a trace, it's hard to bring the case full circle.
It must be frustrating for those people who work on those cases to come up against every single dead end, as much as it's frustrating for the families that no action or movement has happened - sometimes for years.
This year we all need to play our part and take a second to look at their faces - of the cases that Tasmania Police have chosen to highlight for this year's National Missing Persons Week.
You may not be able to help, you may not have ever been in contact with this person, but if they are missing, estranged from their families or living rough on the street - you never know if you will notice them.
But, if you do have any information, if you do have a connection to any of these cases now is the time to come forward.
It might be something that you think is insignificant but it may just be the missing piece to the puzzle.
All of these families deserve closure, and all of these faces deserve to be recognised and respected, throughout this week and beyond.
