Man charged over woman's mountain death

A man will face a special late-night court hearing at Devonport, charged over the suspected murder of his partner in a remote part of northern Tasmania.

The couple from South Australia were bushwalking at Mt Rowland when the 44-year-old woman died in suspicious circumstances, police say.

Her body was found by a search and rescue helicopter on Thursday on the walking track just a short distance from the summit.

Her companion, a 63-year-old man, was taken into custody and after questioning was charged late on Friday.

The couple had been caravanning around Tasmania.

Police said the man is due to face Devonport Magistrate's Court at 8.30pm (AEDT) on Friday.
