Jimmy Barnes is already up and out of bed after undergoing open heart surgery this week. 

In an update posted to Instagram, it was revealed the legendary singer is making a rapid recovery. 

‘Update for all you well wishers sending in positivity. Day three post op we had a few walks up and down the hall way, 250m I’d say’ it read. 

‘A tough and fragile day but here’s a big brave smile for us. Keep up the good work Jimmy’.

In the image, Jimmy appeared in good spirits despite his illness and wore a hospital gown while wheeling along his drip.

Earlier this week, the rocker’s daughter Mahalia provided an update on her father as he recovered in the ICU.

The Australian singer, 41, told Sunrise’s Sam Mac on Friday, Jimmy is ‘doing really well’ but has ‘a long road ahead’.

She also said the support from friends and fans has been ‘incredible’ and they’re ‘very grateful’.

‘The outpouring of love and support was incredible,’ Mahalia said.

‘I know that my mum and all of us really appreciated and still appreciate it because it is going to be a long road ahead.’

The singer was recently rushed to ER following complications from bacterial pneumonia 

‘We’re very grateful for how much everybody loves him and how much people are showing their love for him.’

It comes after Jimmy posed to Instagram on Thursday evening to provide an update on his health, with his wife Jane sharing a positive message.

‘Jane here to update you about our Jimmy. Good progress today in ICU. Some massive tubes have come out and first physio visit,’ she began.

‘Clearing lungs and deep breathing, we know he’s good at that!’

‘Our family thanks each and everyone [sic] for your well wishes, every single one counts so please keep them coming.’

The singer was recently rushed to ER following complications from bacterial pneumonia, but it appears he will make a full recovery soon.

Jimmy informed his followers on Wednesday he was undergoing open heart surgery after a bacterial infection spread to his heart.

Following the procedure, the Scottish-born Aussie took to Instagram to let his followers know he is healthy, happy and likely to make a full recovery.

Late last month, Jimmy was forced to cancel his headlining appearance at Rock the Boat cruise festival in Noumea, New Caledonia, after being hospitalised with bacterial pneumonia.

He then had to pull out of his scheduled performance at By The C in Torquay on December 2 after his condition failed to improve.

Jimmy has a string of sold-out headlining gigs booked for January and February, including multiple shows at the Red Hot Summer Tour festival.

However, Jimmy confirmed on Wednesday his upcoming shows will likely be axed after doctors found his infection had spread.

Jimmy wrote in a statement: ‘Unfortunately I got some bad news late yesterday… despite everyone’s best efforts the bacterial infection I’ve been battling over the last fortnight has apparently now spread to my heart.

‘It’s infected an otherwise healthy valve that was replaced some years ago due to a congenital defect, so I’ll be getting open heart surgery over the next few hours to clear this infection and put in a clean valve.

He went on to express his frustration and shock at the diagnosis, writing: ‘Obviously this is going to take me out of action for a while. I know lots of other people are battling even worse things but it still feel hugely frustrating. Just a few weeks ago I was the fittest I’ve been in decades!

‘Anyway, as you can hopefully appreciate, this has all happened very suddenly so it’s going to take a few days for everyone to figure out what is going to be doable with my upcoming shows.’
