It's day 185 of Amanda's 100,000-kilometre expedition across 3 oceans and 8 nations in Oceania, in honour of the brave, dedicated people who work tirelessly to protect nature from all who seek to exploit it.

They are the guardians of our planet, and nature’s first responders.

They are rangers, and so is Amanda.

On the southern side of the Great Barrier Reef lies a marine wonderland of unparalleled beauty. The waters are teeming with fish, rays, dolphins, sharks, and you might even see turtle hatchlings bursting out of the sandy shore like clock-work toys.

This precious ocean sanctuary is Heron Island, and it’s visitors sure have some stories to tell!

Each of the recipients are transforming communities for the better, such as nurturing the next generation of elite athletes, advocating for Indigenous people in health and law, advancing veterinary medicine, changing attitudes through documentary filmmaking or supporting the blind and low-vision community to travel the world.

Will the replacement of tangible things for virtual alternatives help reduce the global waste problem? Could digital experiences allow society to overcome the behavioural barriers to addressing climate change?

Or will this infrastructure and its energy consumption exacerbate sustainability crisis?
