A young motocross rider hospitalised with a broken tibia following a horrific accident at the Sydney Royal Easter Show has revealed he is in ‘high spirits’. 

Zac Cuthbert was the second of four riders taking part in a gravity-defying jump over a ute and ramp at Sydney Olympic Park on Good Friday.

He took a tumble and landed heavily on the ground, forcing the show to come to a halt for 30 minutes as paramedics treated him, before taking him to hospital.

Mr Cuthbert provided an update on Sunday morning, sharing a photo from his hospital bed, showing his left leg in an external fixation, a surgical technique that uses pins, clamps and rods outside the skin to stabilise fractures. 

‘Thank you everyone who has reached out and showed love and support! Doing well in high spirits,’ he wrote on Instagram, holding two thumbs up.

‘The FMX community are dope.’

His pregnant wife took to Instagram to thank the public for their support during a difficult time.

‘From what was meant to be your last few shows before our boy arrives has tragically come to an early end,’ she wrote.

‘We have a long road ahead of us, but nothing we can’t handle! It breaks my heart to see you go though this, but I’ll be right by your side for every step of the way.

‘Also a massive thank you to everyone that’s reached out to Zac and I. He will be back ripping again as he does in no time.’

The couple first announced in November they were expecting a baby, uploading a photo to Instagram walking through a garden holding hands, and holding a sonogram. 

More than 80,000 attendees flocked through the gates on day two of the iconic annual event on Good Friday.

The Airtime Freestyle MotoX team confirmed on Saturday that Cuthbert was okay and recovering in hospital.

‘He’s come away with a broken tibia, but is more disappointed about not being out there tonight with the boys!’ it wrote.

‘These moments are never easy, but they’re part of what we put on the line every time we ride.’

Prior to Cuthbert’s accident, footage of a harness racing competition in the main showground showed a distressed horse running around the arena before its cart toppled over.

A rider on a horse was seen watching nearby, waiting for a safe opportunity to intervene.

‘Oh no, oh no, no f***’, a spectator is heard in the background.

The clip titled #eastershowfail sparked anger and concern from viewers.

‘This just makes me feel really sad,’ one commented.

Many others expressed concern for the horse.

Show organisers have since assured that the horse is okay.

‘During the light harness class yesterday, a buggy flipped due to a gear malfunction during a horse competition,’ a spokesperson told Daily Mail.

‘No injuries occurred and both driver and horse are okay.’

Organisers expect almost one million visitors to attend the show over 12 action-packed days.

Not a single exhibitor has pulled out of the show, despite the ongoing fuel crisis.

‘They’ve been in months of planning, and they need to be here,’ managing director Murray Wilton told reporters earlier in the week.

‘It’s the pinnacle agricultural event of the country.’

The show has reintroduced an afternoon ticket for families to enjoy the night-time entertainment at a cheaper price.

The Sydney Royal Easter Show runs until April 13.
