The 22-year-old is one of 107 Australian crew members stranded on 40 ships off the coast of the US and the Caribbean after the coronavirus pandemic wreaked havoc on the cruise industry.

Amber left the Macleay Valley in November of 2018 to pursue her dream of dancing on a cruise ship.

"I just want to keep pushing myself and further my career in dance," she told the Argus at the time.

Amber was booked to dance on the Adventure of the Seas cruise liner through to August.

"Amber is safe," her mother, Tina Keast, told AAP on Saturday.

"She is being fed, is well looked after, has a guest room, and they are doing the quarantining and wearing the masks on the ship even though there is no virus on there and no passengers."

The ship offloaded its passengers weeks ago and there have been no cases of coronavirus on the vessel, but a lack of available flights has meant the four Australian crew on board are floating off the coast of Florida not sure when they will be able to return to Australia.

"It's just a matter of not being able to fly home due to restrictions against flying and not allowing crew movement," Amber told the Argus.

Australia's ambassador to the US Arthur Sinodinos used social media on Friday to write a letter to the stranded Australians, assuring them the government was "working tirelessly to assist with your safe and timely repatriation to Australia".

The US Centers for Disease Control and Prevention has prohibited cruise ship crew from travelling on commercial flights in the US.

"This is making it extremely difficult for cruise lines to make viable logistical arrangements for the repatriation of its crew members," Mr Sinodinos wrote.

The Australian government has worked with cruise ship companies across the globe to help facilitate the return of Australian passengers and crew.

Amber was booked on a flight to return home three weeks ago but it was cancelled. Ms Keast said they are hoping a charter flight can be organised to get the Australians home.

The Adventure of the Seas is scheduled to dock at Fort Lauderdale, Florida, on Sunday for supplies, but Amber won't be able to disembark unless she has a flight booked.

"The cruise company is really looking after them well and everyone on the ship is happy," Ms Keast said.

"If they can get a charter flight organised for all of them to fly home, they will all jump on and do it."

"Amber absolutely loves dancing on the cruises," her mother said.

"Unfortunately, this has happened.

"She would like to be home with her family than be stuck on the ship, but she's happy because she is being well looked after."
