A former Brisbane high school science teacher-turned-religious leader has realised his dream to create a reportedly $100 million, 155m version of Noah's Ark that is about to open in the United States.

Australian-born Ken Ham had taught science in the Queensland public school system during the 1980s before he packed his bags and moved to America, becoming one of the most powerful religious leaders in America's Bible belt and founder of Answers in Genesis.

He went on to build a Creation Museum in 2007, a space dedicated to explaining the origins of the universe based on a literal interpretation of the Genesis creation narrative in the Bible.
