Social media is often blamed for eroding traditional culture but, Lisamarie Wia and Emily Papa, are flipping the script.
They're using Tik Tok to teach their native Enga dialect and have found that people are excited to learn.
"We're starting off with the basics first then we're moving onto pronouns the deeper we get in we're doing it in parts so we're heading in that direction," Lisamarie said.
The girls have posted five videos with the first of the videos having already been viewed more than 84,000 times.
Australian National University Linguistics expert Danielle Barth said it's the first time she's seen the social media platform used to keep language going.
"I think it's a great idea especially for languages where we don't have heaps of resources for," she said.
"Tik Tok is a great way to do it because people engage with it."
Emily Papa is hoping that other young Papua New Guineans will follow their lead.
"[To] showcase their culture and be proud of who they are as Papua New Guineans," she said.
