Unique stories, cultures and languages of three First Nations communities are set to be showcased through the Indigenous Literacy Foundation's upcoming Indigenous Literacy Day.

Held in collaboration with the Sydney Opera House, the annual Indigenous Literacy Foundation (ILF) event will see Indigenous communities from Queensland, New South Wales and the Northern Territory showcased with new bilingual books published by the ILF also set to be launched.

This year's Indigenous Literary Day theme, Be A Proud Voice for Country, will explore the significance of Country through many proud voices with ILF ambassador, Jessica Mauboy, taking viewers into three First Nations communities to share their story.

Alongside Mauboy, viewers will learn about dreaming stories from the riverbank in Cunnamulla (Queensland), join teenagers as they explore culture through poetry and art in Vincentia (NSW) and hear incredible stories and songs from children and Elders on the Tiwi Islands in the Northern Territory

"I am so proud to be an Indigenous Literacy Foundation Ambassador and support the incredible programs they run in remote Aboriginal and Torres Strait Islander Communities," Ms Mauboy said.

"Stories are so important. Sharing stories, songs, and keeping the fire of culture alive is so important to who I am.

"These deadly stories from First Nations Communities keep culture and language alive."

Three bilingual books published by the ILF will also be launched on the day, with students from participating communities set to travel to Sydney to participate in celebrations.

They include Indigenous Year 7-10 students from Vincentia High School on the South Coast of New South Wales who created two texts, ngayawanj bagan-nggul, ngayawanj barra barra-unggul (we belong to the land we, we belong to the sea), and bagan, barra barra, mirriwarr (The Boys Who Found Their Way), during workshops with proud Gunai woman, author and award-winning multidisciplinary artist, Kirli Saunders and visual arts teacher and proud Dharawal woman, Jaz Corr.

Vincentia High Aboriginal education coordinator, Aunty Gai Brown said the books are the culmination of years of community dedication and perseverance to revive the Dhurga language.

"It is the first time our community kids have had the opportunity to express their connection to the land and waterways of their Country using the traditional language of their ancestors," Aunty Gai said.

"The books are a visual delight with artworks completed by the students telling these same stories visually.

"It is a proud moment for our school and Community and we cannot thank the ILF enough for giving us this opportunity to showcase our language and culture to a wider audience."

Yalta Ngayuku Papa? (Where's My Dog?) will also be officially launched, a picture book by students of Tjuntjuntjara Remote Community School, home of the Spinifex people, located in the Great Victoria Desert in Western Australia.

Written in both English and Pitjantjatjara, the bilingual book produced through a workshop led by writer Stewart Ennis and community consultant and artist, Ange Leech invites readers into one of Australia's most remote communities.

"There are a lot of dogs in Tjuntjuntjara and the children's dogs all had these fantastic names – Wi-Fi, One-Side, Army Girl, and so on," Mr Ennis said.

"That was interesting enough, but then they began to draw their dogs, and these dog pictures were so full with character...But one of the most important characters in the book is Country itself, so it makes sense that each page of the book is framed by the images of the Tjuntjuntjara red dirt earth."

Indigenous Literacy Day will also see a celebration of Indigenous musics, dance, art language and storytelling held inside the Sydney Opera House, with participants including ILF Ambassadors Jessica Mauboy, Bianca Hunt, Gregg Dreise, Josh Pyke and Justine Clarke.

Indigenous Literacy Day (ILD) livestream host, Bianca Hunt said was eager to participate in this year's event.

"I'm so excited to be hosting this years' Indigenous Literacy Day! This is my first ILD and I can't wait to be involved," Ms Hunt said.

"It is such an important day to highlight First Nations authors and Communities and ensure our kids have access to reading."

Indigenous Literacy Foundation CEO, Ben Bowen said the theme for this year's Indigenous Literacy Day celebration is a continuation of the practice of culture held by Aboriginal and Torres Strait Islander peoples speaking on behalf of Country as the custodians.

"To 'Be a Proud Voice for Country' is as diverse as the many Aboriginal and Torres Strait Islander peoples," Mr Bowen said.

"Some of their stories have been captured on the pages of the three books launching on ILD.

"This year we celebrate the many languages and cultures of Aboriginal and Torres Strait Islander Peoples and their continued role as the voice for Country."

Livestreamed from the Sydney Opera House, Indigenous Literacy Day will be held on Wednesday 4 September from 10:30am AEST with registrations for the free event now available online.
