Kosciusko Coast

Niulakita, the southernmost island of Tuvalu, rises from the southwestern edge of the submerged Kosciusko and Martha Banks. The banks spread beneath the Pacific east of these waters, their shallowest parts a danger to shipping. In 1595 Álvaro de Mendaña sighted Niulakita during his second voyage across the Pacific and called it La Solitaria.
