Lindt Cafe siege survivor Louisa Hope says she's found a "happy place" in raising money for Australian nurses, including those who cared for her following the 2014 attack.
Ms Hope was taken hostage along with her mother and 16 others during the terrifying Sydney siege, which claimed the lives of cafe manager Tori Johnson and barrister Katrina Dawson.
She has since founded the Louisa Hope Fund for Nurses to benefit nursing staff at the Prince of Wales Hospital, so far raising about $180,000 to support six projects.
"It is indeed my most happy place to be involved with the nurses like this," she told reporters at a Sydney function for the charity on Wednesday.
"It's such a privilege for me - to find the opportunity to remind people to be hopeful and keep focused on progressing our world forward."
Ms Hope spoke alongside Police Commissioner Mick Fuller at the function at the Parliament of NSW.
She spent three months in hospital recovering from shrapnel wounds from when police stormed the cafe at 2am on December 16 after gunman Man Haron Monis executed Mr Johnson. Ms Dawson, a mother of three, was fatally wounded by police bullet fragments.
More than three years on, Ms Hope says she's feeling "happy and well in her heart".
"I'm looking forward to improved health, but really focused around the future now," she said.
"I've got a little list of post-siege concerns I'm working on."
Ms Hope's fund gives nurses the freedom to choose a research project or equipment and she says as soon as the money was put on the table, the ideas came "flooding in".
"That said to me that they already knew what they wanted, all they needed was the funding."
Mr Fuller said nurses can't be thanked enough for the difficult jobs they do.
"We often talk about courage in policing and in defence, but there are many who show great courage every day in terms of protecting us in the community," he said.
