Thousands turned out to welcome Roz Savage, 42, as she rowed her 23ft boat, Brocade, into Madang. Several people paddled canoes alongside her as she cruised into the harbour, where well-wishers adorned her with garlands.
"I'm already starting to think about the next one," said Savage, who will rest in Papua New Guinea for a month.
She had previously crossed the Atlantic in 103 days and uses her trips to promote environmental causes. The Pacific endeavour was meant to raise awareness about plastic debris polluting the ocean. She wants people to use biodegradable rubbish bags and reusable shopping bags.
Savage estimates she made 2.5 million oar strokes during her 250-day trip, which was broken up into three different legs.
