Family of missing Aus man delay Nepal trip

The family of an Australian missing in the Himalayas since last month's earthquake have deferred their search mission, as Nepal deals with a second disaster.

NSW man Tyronne White was last seen alive in a remote village on the morning the 7.8 magnitude quake hit on April 25.

His brother Brett had planned to fly to Nepal with his wife and father on Wednesday, but was forced to cancel their trip after a 7.3 magnitude quake on Tuesday.

Brett told AAP the family were devastated by the delay, but said the search would be too dangerous with the country experiencing aftershocks and landslides since the second quake.

Family members have received no recent news about the 44-year-old and still plan to fly to Nepal when it is appropriate, he said.

Mr White, an experienced traveller and trekker, is thought to have been near the village of Langtang when the quake struck.

More than 100 people were killed a week later when a post-quake avalanche hit the northern village, which is a popular spot for Himalayan trekkers.
