Sundalandis the name of a large biogeographical region of South East Asia, a large portion of which had been above sea level during the last Ice Age and later inundated as the glaciers retreated. The term was apparently first used in 1949 by R.W. van Bemmelen (1868-1941) and later by other authorities.
It is worth noting that it is now generally accepted that South East Asia was probably the entry point of modern humans from Africa. Human traces have been found in Papua New Guinea that have been dated to around 40,000 BC.
Some authors have specifically claimed a clear link between Sundaland and Plato’s Atlantis. The Sunda Sub-Oceanic Plain is large enough to match Plato’s description of Atlantis. Its topography, climate, flora and fauna together with aspects of local mythologies, all permit a convincing case to be made to support this idea.
C.W. Leadbeater (1854-1934) who was a prominent theosophist was perhaps the first to suggest a link between Atlantis and Indonesia in his book, The Occult History of Java  , which is now available online(f).
Other investigators have written on the prehistory of the region of whom the best known is probably Stephen Oppenheimer who firmly locates the Garden of Eden in this region, although he makes little reference to Atlantis. More recently, Robert Schoch, in collaboration with Robert Aquinas McNally, wrote a book in which they suggest that pyramid building may have had its origins in a civilisation that flourished on parts of Sundaland that are now submerged.
The first book to specifically identify Sundaland with Atlantis was written by Zia Abbas. However, prior to its publication the Internet offered at least two sites that discussed in detail the case for Atlantis in South East Asia. William Lauritzen(a) and the late Professor Arysio Nunes dos Santos(b) developed extensive websites. Lauritzen has also written an e-book that is available from his site, while Santos developed his views on an Asian Atlantis in another recent book. Dr Sunil Prasannan has an interesting essay on Graham Hancock’s website(c). A more esoteric site(d) also offers support for the Sundaland theory.
An Indonesian researcher, Panji R. Hadinoto, has published on his website(e) a 32 point checklist purporting to ‘prove’ that Atlantis was located on Sundaland. Unfortunately, this checklist is not original but copied from the work of Professor dos Santos.
April 2015 saw further support for an Indonesian Atlantis with the publication of a book by hydraulic engineer, Dhani Irwanto, who endeavours to identify features of the lost city with details in Plato’s account with a site in the Java Sea off the coast of the island of Kilmantan. He has now published a YouTube video in support of his theory(h).
*In 2019, Irwanto published two new books, the first, Sundaland: Tracing the Cradle of Civilisations , in which he offers a compelling case for considering emigrants from a submerging Sundaland as bringers of embryonic civilisation to other lands, where it flourished and developed local variants. It crossed my mind that Irwanto’s contention might explain the origins of the likes of the Sumerian civilisation, among others, which have never been satisfactorily settled!
A 2016 series of graphics shows the gradual inundation of Sundaland from 18,000 BC onwards(g).
Thorwald C. Franke has drawn attention(j) to a recent controversy in Malaya where historian Zaharah Sulaiman has claimed that the Malay set of mtDNA is 63,000 years old, dating back to a time long before the submergence of Sundaland. It seems that Sulaiman had built her claim on some of Oppenheimer’s writings. This veiled suggestion of some sort of racial superiority, through antiquity, was disputed locally.(i)

(j) Atlantis-Newsletter 120
Indonesia in recent years have seen an increasing number of supporters for the idea of Atlantis being located in the vicinity of today’s archipelago, prior to the ending of the last Ice Age, on the submerged continental shelf now frequently referred to as Sundaland. The redating of cave paintings on the island of Sulawesi suggests that they are as old as any in Europe(h), possibly stretching back as far as 40,000 years. A 2016 report(j) has now pushed back the earliest human occupation on Sulawesi to 100,000 years ago.
As far as I can ascertain the earliest suggested linkage between Atlantis and Indonesia came from the leading Theosophist, C. W.Leadbeater (1854-1934). In a booklet, The Occult History of Java, published in 1951 he proposed that Java had been an Atlantean colony.
However, it is reported(g) that Sukarno (1901-1970), the first president of Indonesia, spoke of Atlantis nearly half a century ago when he located it in the Atlantic
William Lauritzen was probably the first to advocate this idea of a Sundaland connection on his website, but it seems that the concept was given a huge boost by the publication of the late professor Arysio Nunes dos Santos’ book Atlantis: The Lost Continent Finally Found.
The idea was given a boost in February 2012 when it was reported(a) by a somewhat incredulous Jakarta Post that the Indonesian president had given his support to a search for an ancient sunken civilisation in Indonesian waters following meetings with researchers including British author Stephen Oppenheimer.
May 2013 saw The Jakarta Post report(b) the publication of a book by local geologist, Danny Hilman Natawidjaja in which he claims that Atlantis was part of prehistoric Indonesia. In the book, entitled Penemuan Atlantis Nusantara (The Discovery of Atlantis in the Archipelago) he claims to base his theory on Plato’s text. However, commenting on the book the Indonesian archaeologist Daud Aris Tanudirjo said that Natawidjaja’s claim was ‘premature’, pointing out that the author had only an English translation of Plato’s text to work with and suggesting that Natawidjaja had no knowledge of ancient Greek. Further background information was subsequently made available(c).
Natawidjaja also claims that a site at Gunung Padang, 120 km southwest of Jakarta may be more than 9,000 years old! Graham Hancock has expanded on this idea(e). Nevertheless, a recent assault on Natawidjaja’s theories in an open letter(m) from Rebecca Bradley, has laid bare the weaknesses in his contentions.
In 2015 Dahni Irwanto published Atlantis: The lost city is in Java Sea, in which he located the biblical Garden of Eden and the legendary island of Taprobane on the Indonesian island of Kilimantan (Borneo) and placed Atlantis off its coast.*Irwanto has built on the work of Santos, expanding Santos’ 32-checklist to 60 headings. In his well illustrated book Irwanto goes further with the suggestion that Atlantean Indonesia was a cultural centre from which post-diluvian refugees spread throughout the world influencing the great civilisations of Asia, the Mediterranean and the Americas.(p.143) He subsequently published Sundaland: Tracing the Cradle of Civilization (1618) in which he develops his idea that ancient Indonesia was a hyperdiffusionist hub. Although I found this book interesting, I thought it over speculative.
While Irwanto’s theories may be hard to accept, at least he presents then in a rational coherent manner, the same cannot be said of Turangga Seta, an Indonesian Atlantis-obsessed group, who place Atlantis in the Java Sea. Their leader, Timmy Hartadi, explains that their beliefs are based on psychic conversations with their ancestors! (n)*
Coincidentally, Delisle de Sales, writing in the 18th century cited an anonymous source who placed Atlantis in Taprobane, considered at the time to be a reference to Ceylon (now Sri Lanka), not Irwanto’s Indonesian Kilmantan.
A short April 2016 blog(k) suggests that Quranic Archaeology may be used to support the idea of an Indonesian Atlantis, a sentiment expressed again a month later(l).
