Outback Gondwana Foundation

Outback Gondwana Foundation (OGF), along with our valuable supporters and volunteers, strives to ensure Outback Gondwana’s heritage is not lost to science but discovered, preserved and accurately documented for perpetuity. With so much still to be discovered and recorded in this unique area of Australia, the history books on Outback Gondwana are yet to be written.
