Three Suncorp executives have completed a 300km, 10-day trek to raise $150,000 for charity.

Commercial insurance EGMs Chris McHugh and Paul Smeaton and Suncorp Bank Branch Manager Di Retchford completed the Simpson Desert Challenge for Youngcare.

The charity offers accommodation and assistance to young people with special needs who have to live in aged care facilities.

Last year Mr McHugh completed a Great Wall of China trek to raise cash for the same cause.
