Jenny Munro, a Wiradjuri woman who has been involved in the Aboriginal Land Rights movement since 1972, was rushed to hospital on January 26 during an Invasion Day rally in Sydney.

Doctors later determined she had suffered a heart attack with Ms Munro since having undergone four bypass surgeries given the severity of the issues.

Her family were unaware that she had experienced previous heart attacks, something her daughter Lorna suggests "speaks to a much bigger issue she and many Elders and land rights stalwarts have experienced".

"After spending a life time breaking barriers and fighting for her people's rights, she has neglected herself in the process."

Ms Munro has worked tirelessly since she was 17 for the improvement of Indigenous rights and livelihoods.

She has worked in a range of roles, from the Aboriginal Medical Service to the Secretariat of National Aboriginal and Islander Child Care (SNAICC), where she served as chairperson.

She has used her experience in community-controlled organisations to launch the Land Council on Erambie Mission and the Aboriginal Legal Service in Moree, as well as raising seven children.

As chairperson of the Metro Land Council, Ms Munro fought to have The Day of Mourning and Protest site heritage listed and she is one of the founding members of the Redfern Aboriginal Tent Embassy which began to protest the creation of a commercial development on the area known as "The Block".

In 2015, Ms Munro was recognised for her lifetime of work as she was awarded the Eddie Mabo Social Justice Award by the National Indigenous Human Rights Awards, in particular for her work with the Redfern Aboriginal Tent Embassy.

After occupying the area in Redfern for more than 400 days, Ms Munro and the Tent Embassy's protests won as the federal government agreed to spend $70 million on homes for Indigenous people.

"Mum has given her all to her people now we need that love and support more than ever," Lorna said.

Her family created a GoFundMe page for her "Care and Support" on February 1st, which raised over $15,000 in its first two days.

The fund is set to aid the family in covering the costs of her bills and utilities, her medical bed, mobility aids and other support needed.
