The federal government will unveil new funding to help people update their electronic health records with details of how they'd like to be cared for in their older years.

Health Minister Tanya Plibersek will on Thursday announce more than $10 million in federal funding to develop new advanced care planning and end-of-life care initiatives.

The changes will also see advance care directives put on the national eHealth record system, so doctors across the states and territories can follow the predetermined wishes of their patients.

At the moment, people can use an advanced care plan to stipulate what types of treatment or interventions they would - or importantly would not - like to undergo if their health deteriorated.

Ms Plibersek said advanced care plans were mostly filled out by the elderly or people with terminal illnesses who may not want some of the "very intrusive and quite difficult" treatments.

She said with the plan logged online, family members and doctors could be fully aware of the wishes of the person if certain situations were to arise.

"We hope that by having this conversation family members will feel more comfortable about the decision their parents are making," she told ABC TV on Thursday.

"Where these advanced care directives exist and where they're followed by family members, those family members deal with the grief and loss of losing someone, much better."

Ms Plibersek, who will on Thursday launch the 4th International Society of Advance Care Planning and End of Life Care Conference, said it was important these state-based plans were unified into one national document in the event of someone having a stroke or heart attack while travelling.

Work has begun in Tasmania to roll out the initiatives, before it will be expanded across the country.
