A Facebook site set up to help find a missing Kiama teen has attracted more than 8000 likes since Friday.

Scott Carrigan’s family and friends are desperately searching for information on the 19-year-old’s whereabouts after he disappeared on Thursday night.

NSW police have revealed that Scott’s last known movements were in the Kiama area.

According to the Help Us Find Scott Carrigan Facebook page, he was last seen dropping a friend home in the Albion Park area at around 9.45pm on Thursday before he later posted a ‘‘sad status’’ to his own Facebook page from the Albion Park area at 11pm.

His phone has been off since.

Scott owns a 2006 black Holden VZ Calais, registration plate AK7 5CO with green P plates, white wall tyres and venetian blinds in the rear window.

The car is pictured with door stickers in several photos posted on social media, but the stickers had been removed prior to Scott’s disappearance.

The Facebook page urges people to double-check the registration if they think they see the car following several reported ‘‘sightings’’ involving one of Scott’s mates, who has a similar car.

Scott is known to frequent the area from Wollongong to Nowra.

Scott is described as being of Caucasian appearance, large build, 190 to 195cm tall, black hair, brown eyes and was last seen unshaven.

Friends and family have taken to social media to spread the word using the hashtag #findscottsafe.

Anyone with information is urged to contact police on 000 immeadiatley.
