A low income health care card helps eligible Australians reduce their healthcare costs by providing access to discounts on prescriptions and some medical services. To apply for one, you typically need to meet certain income thresholds, which are assessed by Services Australia. You can apply online through their website, or in person at a Centrelink service centre.
