Meet The Team

Jason Rahilly
Founder & Director

Jason is the founder and director of B-Alternative, guiding its strategic direction, partnerships, and environmental consulting. With over 15 years as a licensed builder and project manager, he saw the environmental toll of conventional practice, and now combines his hands-on expertise with systems thinking to tackle waste.

He founded B-Alternative to deliver practical solutions that prioritise people and planet—supporting events, councils, schools, and businesses in adopting low-waste systems and circular thinking.

He’s also co-director of Gypco, a sustainability-focused building company, and enjoys cricket, surfing, animals, and the outdoors with his family.

Gretel Tobin
Operations & Communications Manager

Gretel brings a background of environmental science, outdoor education and visual art to shape B-Alternative’s creative direction and drive our waste reduction & education initiatives.

With a system's focussed perspective and a passion for visual communication, Gretel hopes to reimagine communities that are founded in principles of reciprocity - and are therefore more resilient to the impacts of climate change.

Outside of B-Alternative, you'll find Gretel bikeriding, gardening and listening to local live music!

Joshua Davies

Festival & Events Manager

Joshua manages B-Alternative’s Festival and Events services, helping bring reusable and waste-minimising systems to life on event sites, and engage with event audiences in circular thinking.

He values reflecting on how humans occupy space and interact with our neighbours, and our role. Joshua’s creative and community practice has grown through artistic and sustainability-focused engagement at community events. Joshua hopes to keep learning and sharing about human connection and the fabric of nature that we are a part of.

Lachie Pavlovic
Circularity Manager

Lachie is a naturally curious person, a lover of books, travel, and nature. He values connection to place and community, using these as guiding values in daily life.

He believes there is a disconnection between contemporary society and the environmental impact spurring the biodiversity and climate crisis. This is what inspired him to undertake an MA in Sustainability and apply it in the Circular Economy.
