Event Details

The world is changing faster than it ever has before, as we face a difficult future if we continue to inhabit the planet in the way we have been accustomed to. Change is inevitable and brings new opportunities, forcing a rethink of current challenges and seeking of solutions that are inherent in the problem. Exponential development in one area leads to opportunities for innovation in another. Join MC Bernie Hobbs and meet some inspirational innovative young pioneers finding solutions to these problems. The revolution has begun....


Sustainable and innovative solutions don't always need to be high tech to solve challenges across multiple disciplines. These two speakers share how their ideas to improve the lives of many and address major environmental challenges as well.

Sara Rickards is an energetic sustainability ninja who really cares about our planet and has a multitude of ingenious solutions up her sleeve, including co-founding RePurpose for Good which is transforming waste plastic into robotic prosthetic limbs.

Katerina Kimmorley, Co-founder of Pollinate Energy had her a-ha moment while flying over Delhi during the world's biggest blackout and it inspired her to make a difference. We take access to electricity for granted, but for a staggering 1.2 billion people around the world it is a luxury they cannot afford, forcing them to go without basic living requirements such as lighting, cooking and heating. Pollinate Energy is an Australian charity which provides solar lighting to hundreds of thousands of the world's poorest in India, helping to change their lives in the process.


Our future is renewable! It is time to get serious and start thinking about communities, businesses and cities getting off the grid. The City of Sydney Deputy Lord Mayor Jess Miller shares the inside story on how the City of Sydney is tracking to its Renewable Energy Master Plan to have 100 per cent of the city's electricity, heating and cooling from renewable energy sources such as solar, wind and energy from waste by 2030.

Ross Harding, Founder of Finding Infinity views a world powered by renewable energy as inevitable and despite being an engineer believes that it is people, not technology that will bring about the rate of change required. In his spare time, he puts on sustainable solar powered music and talk festivals off the grid in Melbourne and London, and he wants to bring it to Sydney too.


With oceans under threat from plastic pollution and landfills overflowing, Australia must lift its game on managing its own waste. How can we flip the problem on its head and turn rubbish into resource?

Tim Silverwood, CEO and co-founder of Take 3 for the Sea shares what we can do individually as well as government and industry collaborations to take action this year to turn the tide.

Louise Hardman is a scientist and founder of Plastic Collective, which has developed a solution for coastal communities to clean up the ocean of plastic waste, as well as creating employment, income and hope for these remote outreaches.

David Sivyer started a grass roots closed loop system with Feedback Organic Recovery, collecting food waste from cafes turning it into compost which then fertilises fresh produce for sale back to the cafes and at local farmers markets.

Dr Kate Ringvall, Country Manager Sustainability IKEA Australia gives an insight into how IKEA is bringing the Circular Economy to life and doing it profitably.

Gayle Sloan CEO of the Waste Management Association of Australia is a strong advocate for the establishment of a true Circular Economy in Australia and will speak on what collaboration is required from the public and private sectors to make it happen.
