Paparan Sahul
English (EN)
The Sahul Shelf is a vast prehistoric landmass that connected the island of New Guinea, Australia, and the Aru Islands during the last glacial period, when sea levels were approximately 120 meters lower than they are today. This submerged continent is one of the most significant geological features in the Pacific, shaping the biogeography, human migration, and cultural history of the region.

Biogeography
The Sahul Shelf is fundamental to understanding the biogeography of the region. The Wallace Line—the boundary between Asian and Australasian fauna—marks the deep-water channel that separated Sunda Shelf (Asia) from Sahul Shelf (Australasia). Species from Asian and Australasian realms were isolated for millions of years, until sea levels dropped and humans crossed.
Human Migration
The Sahul Shelf was the route through which first humans arrived in Australia approximately 65,000 years ago. These migrants, who originated from Africa via Asia, crossed the deep-water channel between Sunda and Sahul—a feat of maritime navigation that remains one of the earliest examples of intentional ocean crossing.
Cultural Connections
The peoples of eastern Indonesia—especially the Aru Islands and Papua—share cultural and genetic connections with the peoples of Australia and New Guinea, reflecting the ancient Sahul connection.
The Sahul Shelf Today
Today, the Sahul Shelf is submerged beneath the Arafura Sea and the Torres Strait. Its remnants are visible in the shallow seas, the island chains, and the deep cultural connections between the peoples of the region.

萨胡尔陆架是上一个冰期时的巨大史前陆地，当时海平面比今天低约120米，连接了新几内亚、澳大利亚和阿鲁群岛。这片被淹没的大陆是太平洋最重要的地质特征之一，塑造了该地区的生物地理学、人类迁徙和文化历史。 萨胡尔陆架是第一批人类约65,000年前到达澳大利亚的路线。这些从非洲经亚洲而来的移民跨越了巽他陆架和萨胡尔陆架之间的深水通道——这是最早的有意跨洋航行实例之一。
Bahasa Indonesia (ID)
Paparan Sahul adalah daratan prasejarah yang luas yang menghubungkan pulau New Guinea, Australia, dan Kepulauan Aru selama periode glasial terakhir, ketika permukaan laut sekitar 120 meter lebih rendah dari hari ini. Benua yang tenggelam ini adalah salah satu fitur geologi paling signifikan di Pasifik, membentuk biogeografi, migrasi manusia, dan sejarah budaya wilayah tersebut. Paparan Sahul adalah rute di mana manusia pertama tiba di Australia sekitar 65.000 tahun yang lalu. Para migran ini, yang berasal dari Afrika melalui Asia, melintasi saluran air dalam antara Sunda dan Sahul.
