Jimmy Barnes has issued a desperate plea to fans after one of his family members went missing.

The Aussie singer, 69, shared a post to Facebook on Sunday asking fans to help find his son Jackie’s nephew after his family reported him missing.

‘Please help us find Blake, Jackie’s nephew,’ he wrote above the missing person’s report.

Blake Powell, who is only 14, went missing in Sydney’s Castle Hill on Friday and hasn’t been seen since 4pm that day.

‘He is 185cm tall, of thin build, 70kg, Caucasian appearance with an olive complexion, brown hair and eyes,’ the post read.

It went on to say that the young boy is known to take public transport and spend time at Sydney-based shopping malls.

‘Police and Family hold concerns for his welfare given his young age.’

‘Any information – please call Crime Stoppers on 1800333000 or Castle Hill Police,’ the post finished.

The heartbreaking update comes after Barnes faced another medical setback in February, having undergone three different surgeries over the last year and a half.

The Never Tear Us Apart hitmaker has been in and out of hospital since late 2023, receiving two hip operations and open heart surgery.

The musician underwent another operation on his hip just six months after he was forced to get urgent ‘remedial’ hip surgery in August last year.

In a video posted on Instagram, Jimmy appeared using a walking frame to support himself as he carefully made his way down a hospital hallway just a day after his surgery.

Garbed in a patient gown, Jimmy appeared to be in good spirits as he took a stroll through the building wearing compression socks and foot pumps.

‘Please help us find Blake, Jackie’s (pictured left) nephew,’ Jimmy wrote above the missing person’s report.

‘I’m walking, day one. Woohoo! I’ll be jogging by tomorrow. Dancing by Friday,’ he joked.

Jimmy was forced to cancel two months’ worth of gigs last August after noticing an ache in his side while performing in New Zealand, which led to an urgent ‘remedial’ hip operation.

He previously underwent open-heart surgery to fend off a staph infection, which then returned and attacked his hip, leading to surgery and a six-week recovery.

The rock star made a triumphant return to stage in October after his health struggles as he performed with his band Cold Chisel at The Entertainment Quarter.

The Cold Chisel 50th anniversary tour, dubbed The Big Five-0, sold over 150,000 tickets across 16 shows, making it one of the most highly-anticipated Aussie tours of the year.
