When it's free, simple and quick to do, there's no reason to put off at-home bowel cancer screenings which could save your life, First Nations advocates say.

In Australia, eligible 50 to 74-year-olds will receive screening kits to their door automatically every two years. Those aged 45-49 can also request a free kit.

Recent findings from the Australian Institute of Health and Welfare and National Indigenous Australians Agency indicate cancer and other neoplasms are "the leading broad cause of death" for Aboriginal and Torres Strait Islander people.

Between 2014-2018, bowel cancer was the third most common form.

When detected early, more than 90 per cent of bowel cancer cases can be successfully treated.

The National Bowel Cancer Screening Program's campaign 'Bowel Cancer Waits for No One' is encouraging First Nations people to make their health a priority and not put it off any longer.

"As a proud Biripi man and a dad, this campaign is personal to me. We look after our families, we look after our communities, but too often we put off the important things like our health. Thing is, bowel cancer waits for no one. Taking a few minutes to do the free screening test could make all the difference," comedian and campaign ambassador Andy Saunders said.

Mr Saunders said he's proud to be involved with something "breaking down barriers and starting essential conversations for our communities".

"I've done the test myself, and that's why I think it's important to talk about it. It's quick, simple and done at home," he added.

"There's really no reason to put it off when it's something you can do to look after yourself and your family."

According to the National Bowel Cancer Screening Program monitoring report 2026, it's estimated First Nations people participated with the program at a lower rate compared to non-Indigenous Australians; at 38.4 per cent compared to 42.4 per cent.

Between 2016-2017, via the 2019 report, this disparity was much wider.

First Nations people aged 50-74 participated in screenings at less than half the rate of non-Indigenous Australians; 21 per cent compared to 43 per cent.

Lucy Allen was part of earlier campaigns after losing her brother to bowel cancer.

"Four years ago, I shared my story to encourage mob to take bowel cancer screening seriously. I'm still doing my regular tests, because looking after your health isn't something you do once. It's something you keep doing," she said.

"The test is free, quick and simple, and it's something we can all do to look after ourselves and our families."

Kits requests can be made online, via health care professionals or by calling 1800 627 701.
