One of the unit's vessel was forced off the water in August when vandals threw a rock through the boat's front window.

The Marr family, of Canberra, heard the news and wanted to help.

Four-year-old Darcy was sitting on the lap of his mother, Carlene, when he found out. He jumped off and ran straight to his piggy bank.

The eldest, 10-year-old Lachlan, also pulled out a $5 note.

The family are regular visitors to the area, with father Matt's family living at Tuross.

Volunteers at the unit were so moved by the kindness of the boys, they offered them a boating trip on a Marine Rescue vessel at the Moruya River on Friday, October 2.

The family of four spent a morning out in the sunshine, and met members of the unit and the regional operations manager Glenn Sullivan.

Mrs Marr, who preferred land to sea, said it was crucial knowing there were trained rescuers available when her husband went out to sea, if ever he needed them.

Tuross Head Marine Rescue unit commander Alan Blessington said it was disappointing to see the damage in August.

Then to hear of the kids helping was "heartwarming".

Ron Ingram, of Winda Woppa Fishing Charters, heard the boys' story, and offered the family a free charter.

He said good deeds deserved rewards and as bad as COVID-19 had been, it brought the community together in spirit.
