The body of a 54-year-old man was discovered by another bushwalker on a track at Western Arthur Range Traverse in Tasmania's Southwest National Park about 11am on Saturday.
The Queensland man was believed to have been walking alone and initial police investigations indicated his death was not suspicious.
"His family has been notified and our thoughts go out to his family and friends," a Tasmania Police spokesperson said.
The 58km Western Arthur Range Traverse features very rough, steep and unmarked tracks and is recommended for very experienced bushwalkers with specialised skills, Tasmania's Parks and Wildlife Service advises.
The death marks the second in under a week after a man in his 60s was found dead while bushwalking at Cradle Mountain National Park in Tasmania's Central Highlands.
Emergency services were called to an area near Henson's Peak about 12.30pm on Christmas day where they found the man.
A report will be prepared for the coroner after preliminary investigations also suggested the death was not suspicious.
Another two bushwalkers were rescued on Christmas Eve after encountering trouble while trekking near Federation Peak in the Eastern Arthur Range at Southwest National Park.
The men in their 20s activated a personal locator beacon about 8pm on Monday after they became disoriented on a walk without their equipment.
Search and rescue teams and a police helicopter were deployed but the search was delayed due to poor weather conditions.
The men were found uninjured the next morning.
Senior Constable Cam Rennie said bushwalkers needed to ensure they were prepared for all conditions when bushwalking in Tasmania's unique environment.
"The weather in Tasmania can change rapidly and dramatically, so it is important that all walkers prepare for the worst," he said.
Police advise against walking alone and urge bushwalkers to carry sufficient warm clothing, food and emergency communication devices, preferably ones with two-way messaging capabilities.
