The two men went missing in bush land near their property at Millaa Millaa, 100 kms South West from Cairns.
Police were contacted at around 4am this morning and searched at the Sutties Gap Road property, with the Cairns Dog Squad, with additional aerial searches.
The 57-year-old man went bushwalking at around 4.30pm yesterday and failed to return. His son, a 23-year-old man, went looking on foot at around 8pm last evening, and also failed to return to the property.
Both men are related to Cairns businesswoman and internet entrepreneur Nicky Jurd, who drove to the area this morning to assist.
"My dad and my little brother JJ have been found in the forest," Nicky told CairnsBlog. "Everyone is safe and well."
"Thanks everyone for your support. Especially thanks to the SES."
