Nappies for an eight-month-old baby were among the supplies delivered to a group of campers isolated by floodwaters on the NSW south coast since Monday.
Other items delivered to the 41 campers stranded in the Deua National Park on Thursday after frantic efforts by rescue crews to locate the group included satellite phones, food and medicine.
The State Emergency Services's Illawarra South Coast team has led the effort to rescue the campers after floodwaters rose at Bendethera on Sunday night and throughout Monday.
Relatives raised the alarm on Tuesday and SES crews made contact with the group on Wednesday.
Three children were stranded with the groups.
One of the stranded campers, Deborah Baker, told the ABC before their misadventure she'd wished to be stuck on a desert island to help curb her smoking habit.
She said while the thinning supplies were a concern, everything else was okay.
"It's been a wild experience," she said.
But it could be days before the group are able to leave their remote campsite, a NSW SES spokesman said.
"NSW SES, NSW Illawarra Police Rescue Squad, NSW Police Force and NSW Ambulance have been able to reach the sites," an SES spokesman said.
"Lifesaver 23 has visited the sites, checking on campers welfare and restocking with food, nappies, medicines and water.
"All campers are safe and well and the SES will assist in helping the campers head home over the next couple of days."
The rescue effort included combined crews from the National Parks and Wildlife Service and the SES, who travelled from Moruya on Wednesday by road to a flooded crossing.
