They also brought home a bronze and a silver medal each after a three-week trip to the Middle Eastern country.

Special Olympics Committee Mid North Coast chairperson Dianne Davis said it was an outstanding effort from the duo on the world stage in their respective divisions.

"Darren came fifth in the singles in his division, won bronze in the doubles and gold in the team event which was great," she said.

"Jason got fifth in the singles, gold in the doubles and silver in the teams event.

"One of the guys Jason was bowling against came up with seven strikes - and a perfect game is 10 - so fifth place facing someone like that is a fantastic result."

Wallis calls Port Macquarie home, while Holley has plied his tenpin bowling trade down at Forster and they overcame the taxing 14-hour flight to challenge some of the best bowlers in the world.

"It's such a long trip especially for guys with intellectual disabilities because you never know how they're going to react when they get over there," Davis said.

"But the boys performed perfectly.

"Everything went to plan, the carers got them in the running and they're all excited and looking forward to the next one."

Since their return earlier this month, they "haven't stopped talking about" their results.

"The guys put in so much hard work," Davis said.

"They're dedicated to their sport and they love tenpin bowling, but it's also the atmosphere of being involved with the Special Olympics.

"Now all the athletes in the region know that if you put the work in - like any sport - and you plod along each week, these sorts of things can happen."

In total, the Australian team emerged from the competition with an impressive 42 gold, 44 silver and 55 bronze medals.

"They haven't stopped talking about it and they're all talking about the next one in Germany which is four years away," Davis said.

"We've had to slow them all down a bit and tell them they've got to go through the process again and keep up their scores."

Jason faced tough competition from older, more experienced players representing the USA and Malta, but according to his mother, Julie Daskal, who went over to support her son, he held his own.

"I couldn't be prouder," she said.

"Not many people can say they have a world champion in their family."
