Assistant Accountant/Book Keeper in Sydney

For more than 35 years, the Humpty Dumpty Foundation has been helping hospitals and health services care for children by providing much needed medical equipment and initiatives that improve health outcomes. Humpty's mission is to raise funds to provide essential and often lifesaving paediatric medical equipment for hospitals in every corner of Australia. We work with health services to improve the capacity and capability of hospitals and healthcare workers to manage serious and life-threatening medical emergencies through a combined approach of medical equipment and health initiatives.

Each year, the Humpty Dumpty Foundation receives hundreds of submissions from hospitals and health services across Australia requesting a wide range of essential and specialised equipment to help them manage newborn and paediatric medical emergencies. Through Humpty’s Wish List, we provide hospitals and health service centres with the medical equipment they so desperately need.
