Indigenous women have travelled more than 3,000 kilometres to share their language and traditional hand signing at Hobart Language Day.

Anmatyerr woman April Campbell and senior Anmatyerr elder Clarrie Nagamara travelled from Ti Tree to the Tasmanian capital to share iltyem-iltyem, the Anmatyerr name for Central Australian sign language.

Ms Campbell teaches Anmatyerr language to school children and works with elders to maintain language and culture.

She said it was important to educate others about her language.

"We came here to Hobart to share our knowledge, we came to share hand signs that we always use in our community," she said.

"We use them when we go out hunting, when we are talking to deaf people and it is really important for us to use hand sign in sorry business.

"When somebody passes away we always use hand signs. And also we use hands signs to talk to elders."

Ms Campbell said preserving traditional sign language was crucial.

"It is really important for kids to learn hand signs," she said.

"To pass it on to next generations."

Ms Campbell and Ms Nagamara discussed the sign language they use at home with family, on hunting trips and as part of everyday communication.

They demonstrated a number of different signs and also shared traditional sand stories with young children at the event.

Linguist Jenny Green from Melbourne University, who accompanied the two Anmatyerr women to Hobart, said sign language was an important form of communication.

"These journeys to other places really open people's eyes up to different traditions from different places," she said.

"It increases people's knowledge and respect for the fabulous diversity of language practices in this country.

"As a person who has learnt some of these things as an outsider, as a white fella, I think they are beautiful languages."

Anmatyerr was one of about 20 languages, including Spanish, French and Russian, being shared at Hobart's fourth Language Day event.

Also shared was the revived Tasmanian Aboriginal language, palawa kani.

The Tasmanian Aboriginal Centre (TAC) describes palawa kani as being "the revived form of the original Tasmanian Aboriginal languages. It incorporates authentic elements of the original languages remembered by Tasmanian Aborigines from the 19th to the 21st centuries. It also draws on an extensive body of historical and linguistic research".

"There are no living speakers of the original Tasmanian languages," the centre said.

"Spoken records of the original sounds are limited to a few sounds that can only just be heard when Fanny Cochrane Smith spoke on the records of her songs in 1899.

"So to attempt to recover the original sounds and meanings, we have to start from written records made by early Europeans of the sounds they heard, and the meanings they thought they understood when they heard our ancestors speak."

Hobart Language Day organiser Matthew Bishop said about 150 people attended.

He said having Ms Campbell and Ms Nagamara at the event was "a special opportunity to learn".

"It is a nice exchange of culture and opportunity to educate people that traditional sign language exists in Australia."
