Before four-year-old Elliot Parish died from brain cancer three years ago, his father Rick promised to meet him "at the moon" every night at 7.45pm.

Regardless of where he has been in the world since then, Mr Parish has kept his promise.

"Wherever I am, once it's 7.45, I go outside and look at the moon," he said. Tonight, on the third anniversary of Elliot's death, family and friends will gather on Port beach in his memory.

When Elliot lost his 15-month battle with the brain tumour medulloblastoma, Mr Parish vowed to do what he could to find a cure so other families would not have to endure the same heartache.

The former SAS soldier and his wife Emily set up the Telethon Adventurers, which has raised more than $6 million for research and treatment.

Last year, they marked the second anniversary of Elliot's death by holding a brain tumour symposium that brought experts together, the first of its kind in the world.

Mr Parish said the adventurers wanted to build on the brain tumour research laboratory, which they had set up at the Telethon Institute for Child Health Research.

"We're funding international clinical trials," he said. "And we're taking a global leading role in trying to fast-track a cure for childhood brain tumours."
