Nick also admitted that Shane was incredibly welcoming to him when he first arrived on set.
“Crawf was awesome. When I first got there, the staff, they were a bit on their toes – they weren’t sure how I was as a person and they hadn’t been around me before,” he admits. “But me and Crawf, we got along really well.”
Having previously tested out the Warped Wall last year, Shane reveals that he “encouraged” Nick to try out some of the obstacles on the course, but the 26-year-old tennis star decided to leave them to the Ninjas.
“I most definitely didn’t test out the course,” Nick quips.
However, Shane gave in to temptation, revealing that he had another go at the Warped Wall this season.
“I did – I had a go on a higher one this season and I made it to the top,” he boasts, before adding: “I’m like a big kid, so I would love to have a go on all the obstacles. I kept asking if I was allowed, but they were off limits, except for the Ninjas.”
One Ninja who knows the show like the back of her hand is recent Celebrity Apprentice star Olivia Vivian.

Olivia appeared on all four seasons of Ninja Warrior, making history by becoming the first woman up the Warped Wall as well as the first woman to make it through to the grand final.
The warrior tragically lost her father in February 2013 to cancer.
"As some know, I lost to my father to melanoma in 2013, so I’ll do my best to help make sure others don’t go through what my family did," Olivia penned on Instagram.
"To learn and grow we must push past our limits, so get ready to watch myself and a group of amazing humans get uncomfortable and fight for a good cause," she said.
The Warrior paid tribute to her father by choosing the Melanoma Institute Australia as her charity to support in Celebrity Apprentice.
