"I just wanted to help a bunch of kids," Angus Olsen says of the picture books he wrote and illustrated for young children dealing with cancer treatment.

Mr Olsen's daughter, Jane, was two when she was diagnosed with an aggressive form of cancer.

While he sat at her hospital bedside during her weeks of chemotherapy and surgery, the former Disney cartoonist began drawing about her procedures to help Jane make sense of what was happening because much of the information available about her cancer was aimed at adults.

"It helps them be a bit of an authority [and] that goes upwards through families and friends as well," Mr Olsen says of the effect his books have had on young cancer patients.

"It helps ease children into their cancer therapy and can get them through faster. The other great thing it does is that children usually find my work before they find misinformation in the world which is dangerous."

Producing more than 20 books in 24 languages, Mr Olsen's work has gone global but he has not made a cent from more than half a million downloads through Redkite, which provides counselling and financial assistance for families of children with cancer, and also at his own website I Draw Childhood Cancer.

A former resident of Yeoval outside Dubbo, Mr Olsen runs the CafeXpresso kiosk at Katoomba train station.

With Jane, now 10, in remission since May 2017, he says his books are motivated by the "privilege" of being able to "contribute to these children's lives in a positive way".

"The same team that saved my daughter's life are now using my material - that was a powerful moment for me," he says.

Mr Olsen's work earned him the title of NSW Local Hero for 2024 and he is one of eight contenders for the Australia's Local Hero Award to be announced by the Prime Minister on the eve of Australia Day as part of the 2024 Australian of the Year Awards.

ACM, the publisher of this masthead, is official media partner of the Australian of the Year Awards, which are presented in Canberra on January 25.

The following profiles and pictures of each state/territory's Local Hero of 2024 have been supplied by the National Australia Day Council, organisers of the Australian of the Year Awards.

When his daughter, Jane, was diagnosed with an aggressive form of cancer, Angus Olsen sat at her bedside drawing about her procedures to help her make sense of it.

The former Disney artist's artworks and books use simple language to help children better understand their cancer treatment. He's produced more than 20 books, which have been accessed by people in 102 countries.

In 2020, Angus made a series of comics to illustrate the similarities between lockdown and what children with cancer face all the time. Angus has teamed with several charities to create resources and raise funds for childhood cancer research.

Every one of his images can be accessed free from his website idrawchildhoodcancer.com and social media pages.

Betul Tuna is deeply committed to humanitarian and community causes. The Turkish Muslim-Australian - who was born, raised and lives on Yorta Yorta country - has been instrumental in supporting local and international communities during emergencies and making the district a safe, supportive place.

During the 2022 floods in her local community and the 2023 earthquake in Turkey, Betul helped ensure affected communities received necessary supplies and access to essential services.

She also coordinated the design and implementation of a state-funded program that aims to prevent violence against women in migrant and refugee communities and created a bold and successful campaign against female genital mutilation.

Betul co-founded the Hijack'd mobile food van providing culturally appropriate food and creates jobs for local young people. The 38-year-old also co-founded the Point of Difference Studio which champions arts, culture and identity and advocates for culturally safe, respectful and accessible environments in regional Victoria.

Clair Harris believes no child should go without. She started Tassie Mums at her kitchen table in Hobart in 2018 to help families with essentials. Her charity now assists more than 1800 children each year with clothing bundles, nappy packs, activity packs, prams and car seats.

Tassie Mums supplies items to 70 social service organisations across the state working with refugees, families escaping domestic violence or affected by mental health issues and financial stress.

Clair, 42, is incredibly humble, but her efforts have made a real difference. She drums up financial support and clothing donations from across the community and her vision has inspired a large group of regular volunteers.

Last year, Tassie Mums' winter coat and pyjama drive collected more than 800 coats and vests and 600 pairs of PJs to ensure Tasmanian children are warm in winter. The group also helps schools with new socks and underwear.

David Elliott's chance discovery of a dinosaur fossil during routine sheep mustering in 1999 led to the revival of Australia's palaeontology field - and the creation of a palaeo-tourism industry that put outback Queensland on the map.

David's initial fossil discovery was followed by others. As palaeontologists began to return to the region to investigate, David and his wife Judy founded the Australian Age of Dinosaurs Museum of Natural History in 2002 as a not-for-profit charity.

The museum first operated on the couple's property, where they conducted dinosaur digs and built an impressive collection of fossils. Later, it was moved onto donated land.

Today, it houses Australia's most significant collection of fossils from the country's largest dinosaurs.

A major tourist attraction, it serves as a centre for Australian paleontological research and discovery. David, now 66, was recognised for his contributions to science with an Order of Australia Medal (OAM) in 2015.
