A young Australian mum has decided not to tell her 5-year-old son he's dying.

Hannah White's son, Joshua, was diagnosed in 2016 with a terminal form of cancer and to avoid casting a shadow over his remaining days she decided to keep the hurt hidden and keep him smiling.

Joshua has rhabdomyosarcoma, a rare form of soft tissue cancer.

"If you actually met my little boy, he's full of life," Hannah told Nine.

"He's so energetic and when you see him you wouldn't think that his fate has already been determined, at all, like you cannot tell he is sick.

"I think I just want to keep it that way and I don't want to… I don't even know how to start a conversation with him about it."

While Hannah, 23, is glad she has decided not to tell him about his diagnosis, if he asks she says she wouldn't lie to him.

"It just hasn’t come up yet."

She also has two younger children Torii-Lee, four and Maleeyah, two who haven't asked about their brother's illness.

"I don't think they would understand either," she said.

Hannah and her three kids were on holiday in Queensland when Joshua got ill. They took him to hospital where they were given the news.

The then four-year-old went through 40 cycles of chemotherapy and 24 cycles of radiation treatment.

While Joshua was undergoing treatment and supporting him, she had to make a tough decision to miss her youngest, Maleeyah, walking and talking for the first time.

"It was hard, and still is hard but at the end of the day, I guess you have to do what you need to do to save your child."

She says the community were supportive of her decision not to tell him the entire truth.

"Questions don't get asked, especially when my kids are around."
