Tas holds a B.Sc. (Earth Science with first class honours), a B.Eng (hons) and a doctorate in mechanical engineering, all from the University of Queensland.

Using his varied experience, Tas has developed a biblical geological model to connect geological structures in the field with biblical history.

He has applied this geological model to the Great Artesian Basin in Australia, the basement rocks in Brisbane and the Banks Peninsula in New Zealand.

He and other creationist geologists are now applying the model to other areas of the world.
