The local aborigines in South Australia remember the rising sea level ‘cutting off’ Kangaroo Island (and those on it) about 6000 years ago. Backstairs Passage average depth 40 metres (max, 73 metres).
The separation by flooding of Bass Strait must have been earlier as its average depth is 50 metres (wikipedia) or 60 metres (wikipedia). The rising sea level “forming a marine embayment from 11,800 BP to 8700 BP and the basin rim was completely flooded by about 8000 BP, at which point Bass Strait was formed and Tasmania became a separate island”.
The landscape evolution of the East China coastal plain, one of the most important restrictive factors in the development of Neolithic culture, has largely been governed by sea level changes during the Holocene...... spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution, which ultimately governed by sea level changes.
At about 7 ka, sea level rise decelerate remarkably. In the meantime, East Asian summer monsoon strengthened significantly, which enhanced erosion in the drainage and sedimentation in the lower reach of the rivers, leading to land formation and propagation in the coastal region. The vast, extremely flat and fertile land provided a cradle for Neolithic ancestors, with resplendent cultural achievements during Liangzhu period.
The East China coastal plain is located in the lowest reaches of large rivers, with a landscape of extreme flatness with low elevation and dense networks of drainages, and is therefore vulnerable to extreme climatic-environmental events, which exerts great influence on the distribution, migration and succession of Neolithic cultures.
