Exploring Humanity's Ancient Connections
Perth & Sydney · December 2027Australia is home to one of the world's oldest continuous cultures and some of humanity's greatest ancient mysteries. Yet despite its extraordinary heritage, it has often been overlooked in international conversations about ancient civilizations, megalithic sites, sacred landscapes and humanity's forgotten past.
The Pleiades Alliance Foundation was established to change that.
Our vision is to create an international platform where respected researchers, Indigenous Elders, authors, explorers and curious minds come together to share discoveries, exchange ideas and inspire a deeper understanding of humanity's shared story.
Following the tremendous success of Dr. Sam Osmanagich's 2025 Australian Tour, we are delighted to welcome him back to Australia in December 2027 for an even more ambitious programme of events.
The Bosnian Pyramid of the Sun — Visoko, Bosnia & Herzegovina
Since his last visit, ongoing research at the Bosnian Pyramid Complex has revealed remarkable new discoveries, further expanding our understanding of one of the world's most fascinating archaeological sites and attracting growing international attention.
The Pleiades Alliance Conference 2027 will bring together an outstanding group of Australian and international speakers.

Rather than presenting fixed conclusions, the conference encourages respectful dialogue, open-minded exploration and meaningful conversations between researchers, Indigenous knowledge holders and participants from diverse backgrounds.
The pyramid complex mapped — sacred geometry across the Visoko valley
Decades of research have uncovered an extraordinary underground network — the Ravne Tunnel labyrinth, megalithic stone blocks, and chambers rich in quartz crystal, believed by researchers to hold unique energetic properties.
