EXCLUSIVE: Survivor winner Jericho Malabonga (R) will use $500,000 prize money for FIRST TIME to help co-star Luke Toki (L) achieve his dream of taking his autistic son to Disneyland

That's generous! Jericho's surprise trip will be the first major spend of his Survivor $500,000 grand prize after being crowned the winner of the Channel Ten's reality show last October

Luke, who formed a close friendship with Jericho on the reality TV show, had expressed his desire to take his two children to Disneyland if he won.

He revealed last year to OK! magazine that he was taking his role on the reality TV competition seriously for his family.

The Perth resident said winning the $500,000 prize would mean the world to his two sons, Lennox and Nate, who were diagnosed with autism and global development delay (GDD) respectively.

'I want to take them to Disneyland... pocketing the prize money would cover that, as well as another trip,' he said at the time.

'I wanted to help fulfill his dream to take his entire family to Disneyland!' Jericho said, joking he wasn't going to help with his other hope of 'putting it all on red' as expressed on the reality TV show.

He said the plan has been set in place since March, but Luke only told his wife and two children of the exciting trip last weekend.

Jericho explained the children were very excited for the holiday, laughing as he added: 'The kids are ready to go now.'

Surprisingly, this is Jericho's first major thing to have spent his impressive half-a-million prize money on since.

'I wanted to make sure I didn't take anything away from him. This was still 'his thing' to do for the kids. So I said, you buy the family the tickets to Disneyland and I'll help you get them there,' he confessed.

Luke, a Perth mining technician, is beyond excited for the trip and has taken to Instagram with colourful posts announcing the holiday.

'Who would of thought! A year ago I was starving, tired, and at the most miserable place on earth, to then be heading to Disneyland the "happiest place on earth" with my family and best mate - I cant wait,' Luke told Daily Mail Australia.

Taking a cheeky swipe at his close pal, he added: 'I just hope Jeri is tall enough to go on all the rides.'

He announced the news on Instagram, writing: 'After last year's effort on @survivorau I said if I won, I would take the family to @disneyland... Well I didn't win but I made a life-long friend out of it and together we have decided to make a dream come true. The happiest place on earth here we come baby!'
