Since 2011, the Indigenous Literacy Foundation has helped over one million books reach hundreds of remote communities around the country.
In the last six years alone, over 600,000 have been delivered in a partnership with Australia Post, now extended for another three years.
AusPost and ILF first partnered in 2020, reaching over 400 communities with their work together helping drive the foundation's effort to support culture, Country and language-centred literacy.
ILF says Aboriginal and Torres Strait Islander communities "should be able to determine how to best teach and educate their children".
ILF also provides early learning resources and mentorship programs, and helped get 158 books in English and 48 First Languages published by community.
Last year alone, with AusPost, over 140,000 books reached communities.
"Our long-term partnership with Australia Post is one we are truly proud to celebrate today and is a testament to our shared values and commitment to invest in Communities today for tomorrow's opportunities," ILF chief executive Ben Bowen said.
"The extension of this relationship is the foundation for the ILF to confidently grow our investment in the literacy aspirations of Community, knowing that reading opens doors to a world of opportunity."

The partnership is also slated to continue supporting year 11 and 12 students from remote areas to Sydney for a week-long writing and illustrating workshop.
ILF's Create Initiative sees the students publish a book through the workshops.
Australia Post has also highlighted ongoing commitments to Indigenous Literacy Day, ILF's annual national celebration.
"We're proud to continue our long‑standing partnership with the Indigenous Literacy Foundation. Through our delivery network, we help ensure these educational resources continue reaching First Nations children in remote Communities, supporting a love of reading and a strong sense of identity," AusPost general manager of community and stakeholder engagement Nicky Tracey Tracey said.
Mr Bowen said for ILF, it's an honour to do their work investing into First Nations communities "through the distribution of books, publication of Community stories, and mentoring young people toward fulfilling career pathways".
"Aboriginal and Torres Strait Islander peoples are best placed to make decisions for their Communities. Australia Post's investment into literacy via this partnership is key to us connecting remote Communities with culturally relevant literacy resources and programs - helping Communities to reach their literacy goals and enabling them to make decisions that strengthen their futures," he said.
