Register your interest and be the first to hear about the 2020 Seinna’s Gala Dinner at the Sergeants Mess Chowder Bay Rd, Mosman!

Neuroblastoma is not well known in the community; most Australians wouldn’t even be aware of it, despite this disease taking the lives of more children under five than any other cancer.

Sienna, the daughter of Lucy Jones and Oliver Hoffmann, endured six rounds chemotherapy, surgery, a stem cell transplant and radiotherapy and yet, despite her extraordinary resilience, could not overcome the aggressive form of neuroblastoma she had. She died in February 2010 when she was just two and a half years old.

The very first dinner held in Sienna’s honour was in March 2010 and so far, these events have raised over $500,000 for vital research.

This year’s Sienna’s Gala Dinner will be held on Thursday 20 February 2020.

The superb Sergeants Mess at Sydney’s Chowder Bay will be the stunning waterfront venue for next year. We will provide a delightful evening of delicious food, wine and entertainment. 

Through ticket sales, silent auctions, raffles and our signature pink and gold balloon prizes we will be raising vitally needed funding for research into a cure, so all children diagnosed with neuroblastoma get the chance to grow up to live long and healthy lives. If you, or your business will like to support through prizes, sponsorship or auction items please contact us on 

Thank you for helping us increase the amount of research into neuroblastoma, to fund leading scientists who can unravel more of the mystery of neuroblastoma, and to ultimately to work towards a cure for this disease.
