Farmer Auto Village helped organise the evening.
She did not know what Mr Gault would whip up for his guests during the demonstration but he was a great presenter to watch, she said.
"He's charming and funny but a natural and polished presenter. He's quick to laugh with his cheeky little grin which will make it fun. Obviously, he's wildly passionate about food. It will be a very special night."
The organisation has to raise $2.5 million a year to keep its doors open to help the local community.
