Back then also, as there's a subducting tectonic plate boundary running through there - the Weber Line is somewhat similar to the shape of that boundary in that area.
The ocean reaches depths of 7000m in trenches between the Sahul and Sunda shelves, and, at least during the last glacial maximum, 21K years ago, the sea level was only 140m shallower.
