She carried all necessary provisions with her and as a condition of the record didn't accept any assistance.

Her designated onshore contact Tony Roberts said she was in high spirits when they spoke on the phone on Tuesday afternoon.

Her emotions were of the "whole elation of being home and being safe," Mr Roberts said.

"The main thing I expressed to her is what she's just achieved, what no other Australian woman has ever done," he said.

It is the second record for Lee, who in 2017 became the fastest woman to row 1 million metres.

It wasn't all smooth sailing through the Atlantic Ocean for Lee, who suffered from a cut on her hand which wouldn't heal, diarrhoea from the dehydrated food she was eating, a broken rudder and a pipi infestation, along with loneliness and exhaustion.

Mr Roberts, who has more than 50 years of sailing experience and who has also travelled solo across the Atlantic Ocean on his boat, communicated with Lee via a satellite phone and coached her throughout the trip.

"I knew how to push her, I knew how to keep her mind active, I knew how far to challenge her so that she would get the job done before she would break down," Mr Roberts said.

Lee, who lost 14kg through the trip, had a BBQ onshore and had already drunk "a couple of rums" by the time she spoke to Mr Roberts.
