Ex-soldier who was supported by donations from The Wiggles star Anthony Field, ...

Anthony Field has shared condolences for ex-solider Brendan Nikolajew, who has died at age 30, just weeks after receiving a terminal cancer diagnosis.

In a post shared to Twitter, The Wiggles star, 58, wrote: 'Rest In Peace Brendan' alongside a photo of Brendan with his family. 

The performer had earlier pledged to donate royalties from The Wiggles new album, Lullabies With Love, to Brendan's family. 

The children's entertainer, who is also a former army man himself, told Sense Music Media that he'd removed his name from every track on the album and replaced it with Brendan's, so that all co-writing royalties would flow directly to the Nikolajew clan. 

'[Brendan is] one of those guys who you talk to and he just brightens up your life, even though he's going through the worst you could be going through,' Field told the publication.

'[Lullabies with Love] will give royalties to the kids and the family for a few years. Every so often, they'll get some money, which will be really great,' he added. 

'I never thought that I'd be receiving support and admiration from such a legend. Anthony has given so much and it's too humbling,' Brendan had said at the time. 

The former soldier and loving father-of-two was told he had just weeks to live after finding a cancerous lump on his testicle. 

Mr Nikolajew, who lived in Queensland's Moreton Bay, was first diagnosed with cancer after discovering a lump on his testicle three-and-a-half years ago.
