Message in bottle sparks NSW coast search

A message in a bottle that washed up on a NSW south coast beach has sparked a search of waters along the coastline.

A Westpac Life Saver Rescue Helicopter scoured the NSW coast from Broulee to Bermagui on Tuesday.

Police say the note, reportedly dated January 2, reads: "enough food for two days, boat out of fuel, scared, send help".

The note indicated two people were in need of help.

The rescue chopper returned to base after failing to find any sign of a boat or debris.
