Copper coins up to 1000 years old found in Australia could completely rewrite the story of our European history.

Archaeologist Mike Hermes found an ancient coin lying on a beach last year in the Wessel Islands, which are part of the Northern Territory. Mr Hermes believes the coin is at least 600 years old and from 10,000km away from Kilwa, an African island that is now part of Tanzania.

“The Portuguese were in Timor in 1514, 1515 — to think they didn’t go three more days east with the monsoon* wind is ludicrous*,” he told The Guardian.

“We’ve weighed and measured it, and it’s pretty much a dead ringer* for a Kilwa coin.

“And if it is, well, that could change everything.”

So far, tests on the coin haven’t led to a firm answer on where it came from.

In 1944, five coins were found in the Wessel Islands that were later proven to be 1000-year-old Kilwa coins, opening up the possibility that sailors from distant countries landed in Australia much earlier than thought.

During World War II the Wessel Islands — an uninhabited group of islands off Australia’s north coast — were an important place for defending the mainland from attack.

Australian soldier Maurie Isenberg was stationed on one of the islands to operate a radar station and spent his spare time fishing on the beaches.

While sitting in the sand with his fishing rod, he discovered a handful of coins in the sand.

He didn’t have a clue where they came from but pocketed them anyway and later placed them in a tin.

In 1979 he rediscovered his “treasure” and decided to send the coins to a museum to get them identified.

The coins proved to be 1000 years old.

Still not fully realising what treasure he held in his hands, he marked an old map with an “X” to remember where he had found them and they were mostly forgotten for another 34 years.

In 2013 anthropologist* Ian McIntosh led an expedition to the Wessel Islands, but this time no more coins were found.

Aboriginal Australians are thought to have first arrived on the mainland by boat from the Malay Archipelago* between 40,000 and 60,000 years ago.

Captain James Cook declared Australia “terra nullius” (empty land) and claimed it for the UK in 1770.

We know that Captain Cook wasn’t the first European to step on Australia’s shores.

In 1606, a Dutch explorer named Willem Janszoon reached the Cape York peninsula in Queensland, followed a few years later by another Dutchman Dirk Hartog.

And the Spaniard Luiz Vaez de Torres discovered the strait* between Papua New Guinea and Australia in 1606, which was later named Torres Strait in his honour.

However, none of these explorers recognised they had discovered the famed southern continent, the “Terra Australis Incognita”, which was shown on many world maps of the time.

According to a team of Australian and US historians, archaeologists, geomorphologists* and Aboriginal rangers, the five coins found in 1944 date back to the 900s to 1300s.

They are African coins from the former Kilwa sultanate*, now a World Heritage ruin on an island off Tanzania.

Kilwa once was a wealthy trade port with links to India in the 1200s to 1500s.

The trade with gold, silver, pearls, perfumes, Arabian stoneware, Persian ceramics and Chinese porcelain made the city one of the most powerful towns in East Africa at the time.

The copper coins were the first coins ever produced in sub-Saharan Africa, and, according to archaeologists, have only twice been found outside Africa: once in Oman and the Australian find in 1944.

Archaeologists have long suspected there may have been early sea trading routes that linked East Africa, Arabia, India and the Spice Islands even 1000 years ago.

Or the coins could have washed ashore after a shipwreck.

When Isenberg discovered the copper coins he also found four coins from the Dutch East India Company — with one dating back to 1690.

VCOP ACTIVITY
In the eyes of a soldier

Imagine you are Maurie Isenberg, stationed on an uninhabited island. Write a week’s journal entry retelling your time on these lonely islands.

You may like to recount from his first week, or after some time has passed and how he is feeling.

You can complete one entry for the week, or a couple of entries — after all you are alone on an island, what else do you have to do?

Don’t forget to include discovering the coins and creating your own treasure map.
