Mystery as father-to-be boxer nicknamed 'Lucky' dies just after the biggest fight of his career

An Australian-based Solomon Islands boxer and father-to-be named Lemuel Silisia has tragically died just days after a title bout in NSW, with his cause of death currently unclear.

Silisia, who had lived and worked in Australia since 2021, took part in the biggest fight of his life on Saturday when he fought for the World Boxing Foundation Australasian Super Lightweight Title in front of approximately 1000 fans.

Despite knocking down his Aussie opponent Adam Flood in the third round, Silisia went on to lose the bout by a points decision.

Following the eight-round bout in Tamworth, Silisia reportedly posed for photos with fans and spoke to media.

In the days following, family members let his friends and followers know that the talented pugilist was fighting for his life in hospital.

His death was announced by family members on Wednesday night, but the cause of death remains unclear. 

Silisia's brother Colson posted a tribute online, explaining that after not responding to brain function tests his brother was declared medically dead.

'His brave heart continued to fight until it eventually ceased beating today [Wednesday] at 5:24pm, when he was called to be with the Lord Jesus Christ,' he said.

'In this time of immense mourning and sorrow, the Silisia family kindly asks for your support and prayers. Your love, thoughts, and prayers provide solace as we navigate through the pain of this loss.

'Though our hearts ache, we hold dear the memories we shared with him, preserving his spirit in our hearts.'

The fighter who was known as 'Lucky' to his family members told media earlier in the year why he had moved to Australia.

'In the Solomons, even if you're good at sport, to be successful it depends on who you know, rather than what you know, but Australia is a big country with lots of opportunities in sport,' he said.

On Wednesday evening, Silisia's boxing club One2 Boxing in Tamworth took to social media to post a short message.

'The last few days we have been bedside with our beloved Lemuel, family and friends,' the club said.

'Your O2B family are heartbroken and we promise your legacy will live on. Rest in peace Lems.'
