OUR MISSION: Promote diversity in aviation occupations and STEM education while celebrating both old and new aviation milestones. Our names are Cathy Babis and David Geers. David, owner of the seaplane, and Cathy, a pilot for over 5 decades and a member of the rare .47% of US pilots who are women who hold seaplane ratings, will fly a 1600lb/726KG 2-seat amphibious seaplane called a SeaRey around mainland Australia beginning on the same date as the first circumnavigation - April 6th.

Our approximately 60 day journey will encompass over 200 landings on both land and water and 18,270 Kilometers/11,350 Miles of awe-inspiring landscapes, encompassing coastal regions, remote islands, and diverse terrain.

We are seeking contributions to cover some of the costs and logistics involved in this monumental journey. Any contribution, big or small, will make a significant impact on the success of this historic endeavor.

We estimate the total cost of the trip to be $400-500USD/day which works out to be $30,000USD at the high end. We plan to publish a book and documentary of our endeavor and those things will require extra funds for editing & video production.

Fuel can vary from $8/gal to over $20/gal in remote areas. Lodging is another major expense. Sometimes we will be sleeping under the stars. Cathy will be halfway around the world and away from her home for about 75 days. David will be away from work in Australia for 2 months. Other expenses are food, landing fees, aircraft maintenance, ground support and media support both on the trip and post-production.

We are deeply grateful for any level of support or simply your good thoughts and prayers for a successful trip!

We are also seeking corporate sponsors. If you are interested, please contact us.

We hope our flight inspires and motivates people of all ages, genders, and races to consider embracing aviation as a vocation or avocation - from young girls just selecting a career to older women who may have put their flying dreams aside years ago. We believe that every barrier is meant to be broken. It's an honor to celebrate the circumnavigation’s 100th anniversary and pay tribute to the pioneers who paved the way for us, while achieving a “first” for female pilots.

After completing our 60 day journey, we plan on speaking to schools about our experiences and helping promote aviation to all generations, genders, & ethnicities.
