NSW Maritime is investigating a boating incident at Bithry Inlet, near Tathra, South Coast NSW.
Yesterday, three young men survived the capsize of their 3.7m boat.
The boat was reported to capsize just over 100m offshore.
It is believed none of the three were wearing lifejackets.
While the details of the incident remain unclear, it is a reminder of the importance of lifejackets.
New rules in November 2010 make it compulsory to wear lifejackets in a range of heightened risk situations and that includes when boating offshore in small craft.
Lifejackets are compulsory for all on board when offshore in boats of less than 4.8m. For more details on lifejackets go to http://maritime.nsw.gov.au/campaigns/lifejacket.html
