Searchers will today scour a Tongan island for two men missing after their yacht was wrecked last Thursday night.
Attempts to search the volcanic island of Late, west of Vava'u, have been hampered over the past two days due to high seas with 3m swells.
Aerial and on-water searches have so far failed to find the two Australian men, both in their sixties.
Their 50ft Bavaria yacht Navillus broke up after it ran aground on Thursday.
The pair contacted a relative in Victoria via satellite phone, and an emergency locator beacon was activated at the same time, about 10.30pm.
