Overflow Design & Communication founder Leonie Ferreira Mendonça has more than 24 years’ experience as a Graphic Designer / Art Director. She has produced work for agencies, large companies, organisations and charities developing everything from new brands to catalogues, advertisements, brochures, packaging and point of sale.

Leonie is happiest working at her computer creating ideas that work for you. And, as a point of difference, she offers a complete end-to-end service because she works closely with Sydney’s long format digital printing house - Offset Digital Partner and Stikpix Signage & Graphics.


Leonie Mendonça served as Senior Designer (Graphic & Digital) within the Communications & Digital Team at Amway of Australia and New Zealand from 3 November, 2017 to 2 May, 2018. During her tenure at Amway, Leonie has been an excellent member of the team. She has exhibited a high level of commitment to all the projects and initiatives at hand, and has shown great diligence, hard work, good communication and stakeholder management, and was very organised with her work. She showed a lot of respect for business timelines and priorites, was a quick self-starter and contributed extensively with her knowledge of design, production and post-production processes.

I have received very positie feedback about Leonie's work and work ethic from management members whose design projects she managed, and she will most definitely be missed.

It has been a pleasure working with Leonie, and I am sure she will be a great contributor to any team that she is part of in her future endeavours.

Leonie has been creating custom designs for Racing NSW and Young Professionals in Racing for several years now and her work is always impeccable. This includes advertisements for social media, magazines, annual reports, industry reports, corflutes, large posters, gift vouches, inforgraphics, flyers and cards. A basic brief is enough for Leonie to start work and if she has any ideas or thinks a different method will be better she makes suggestions. 

Leonie is easy to talk to and always keeps me up to date with her progress. Leonie's designs are vibrant and stylish and draw attention for all the right reasons. I have no hesitation in recommending Leonie to my colleagues and friends for all their graphic design needs.

Leonie Mendonca recently completed the Inside Waste Industry Report on a contract basis. It is a 138-page full colour A4 size publication with lost of graphs and tables that had to be created from scratch, to a certain design brief.

Leonie not only completed the design and layout in 3 weeks, but showed a professionalism and calmness under pressure which we all found admirable. In addition to this, she was very polite, punctual and prepared to do whatever required to get the job done well. Therefore, I would not hesitate in recommending Leonie as a contract graphic designer.

- Sam Panetta, Graphic Designer

We have been fortunate to work with Leonie on a number of occasions over the past few years. She is responsible for all our design and print requirements, including new window signage, promotional material, banners and advertising material for bulk mail out. All of which have been designed by Leonie.

It is always a pleasure to work with Leonie, she listens and then creates and her response time to all request is prompt. She works within our deadlines and always delivers a first class product. I have no hesitation in recommending Leonie to anyone who requires her services and expertise. I also find her a very warm, helpful and capable person to work with. A rare find in todays market.

Ms Leonie Mendonca has been designing the colour section of our Racing Magazine for just over five years. During this time Leonie has been a pleasure to work with and has a strong grasp in understanding a client's requirements. Leonie designs competently and hastily when required to meet our deadlines and her work is of excellent quality.

I would have no hesitation in recommending Leonie to any client requiring vibrant, skilled and top notch graphic design work, completed within strict deadlines.

- Mark Brassel, Public Relations & Media Manager

Leonie Mendonca was employed at Blue Gecko from 23 Sept 2002 until Feb 2005 as a Graphic Designer. Initially, she worked across a range of work in the studio, eventually settling in as our main Corporate Magazine Designer. 

Leonie showed dedication and interest while she was here, handling difficult client request and adapting the magazine's style to suit. She worked well with the other staff here and her accumulated knowledge of our specific clients and their needs was indeed a valuable asset. She left us to pursue more time with her young family and we wish her every success for the future.
- Adam Milgate, Director

Leonie worked with our company in the capacity of Graphic Designer from March 2000 until 24th Dec 2001. Working on a Mactiosh PC and using all standard software applications, Leonie was responsible for the design and layout of business and lifestyle magazines and occasionally corporate collateral. She reported to the Head of Design and worked closely on a day-to-day basis with the editor of each publication.

During her tenure with GBC, we found Leonie to be a proficient magazine designer, fully able to undertake her task with a minimum of supervision. She is both conscientious and reliable and when needs dictate, fits her personal life around meeting publishing deadlines.

I have no hesitation in recommending her for any similar role and wish her every success in her future career.

- Barry I. Gray, Managing Director

Leonie has been involved in all of these activities and performed consitently to a high standard. Her job responsibility as Studio Manager was supervising the activites of the other studio personnel. She was also willing to put in extra time and effort to meet deadlines.
