Nic Seton

Nic Seton, Deputy Program Director (Engagement) 

Nic Seton returned to Australia after seven years campaigning with Greenpeace, WWF, UKYCC and 10:10 in the UK. Nic is a strong advocate for people-powered change and utilises new technologies to bring about new possibilities.

Nic has crossed oceans to protest Arctic oil, coordinated livestream events with hundreds of thousands of viewers, worked alongside artists and DJs to mobilise people to protect critical habitats and, sparked embarrassing moments for climate skeptics, like Tony Abbott, with fabulous friends, like Emma Thomspon. Swoon.

Nic is a child of the eighties – he grew up with mobile phones, the Internet and the UN Framework Convention on Climate Change. Environmental studies led to activism. And As an early member of AYCC, he traveled overland, to the 2008 UN Climate Conference in Poznań, Poland. Ever since then Nic volunteered, interned, worked and campaigned to stop climate change... Thank goodness we all got involved while we could ;)

“Greenpeace is a movement that makes the impossible possible. It’s just a matter of imagination.”

Nathaniel Pelle

Nathaniel Pelle, Senior Campaigner

As the Sydney-based Oceans Campaigner, Nat leads Greenpeace’s campaign to protect Australia’s oceans from reckless corporations and government inaction. He currently runs a project that aims to connect Australians to the Pacific and to protect fishing stocks. As one of the few Greenpeace offices connected to the Indian Ocean, Nat certainly has his hands full conducting research and action against destructive fishing in this region.

Nat coordinated the public campaign in 2012 that led to the MV Margiris supertrawler being banned from Australian waters for two years. He also led the Australian campaign that made canned tuna brands like John West, Coles, IGA, Aldi and others stop supporting destructive fishing methods.

Nat grew up in Newcastle where he worked as a graphic designer. Against the backdrop of this large coastal, industrial town his love of the ocean and concern for workers rights and livelihood developed. He studied Peace and Conflict, Media, and Environmental Politics in Newcastle, Sydney and Edinburgh, Scotland.

“My working life has been varied but nothing beats working for Greenpeace. We are ordinary people from all walks of life and every corner of the globe just trying to make a difference.”

Nikola Čašule, Climate and Energy Campaigner

NikolaNikola joined Greenpeace as a Climate and Energy Campaigner in early 2014.

He previously worked as a university lecturer and researcher in the United Kingdom and Australia and has taught at the University of Oxford, Sydney University and the ANU. He holds a PhD in Ancient History from the University of Oxford and a BA (Honours) degree from Macquarie University.

Nikola joined Greenpeace after deciding that he could no longer focus on studying the rise and fall of ancient civilisations without doing everything possible to help deal with the climate crisis facing our own.

“Climate change is the most serious threat facing the human race. The extent to which we take action will not only determine whether we can live on a peaceful and prosperous planet but also how our generation will be viewed by our children and grandchildren. We can’t let them down.”

Matisse Walkden-Brown

Matisse Walkden-Brown, Head of Pacific Net

Matisse Walkden-Brown joined Greenpeace in early 2015 as the Head of Pacific Net. Having grown up in Fiji on a coconut grove family-run resort, she now puts all of her wide-eyed enthusiasm into ensuring sustainability for the Pacific and its people.

Working throughout the 24 island states, Matisse is passionate about creating a united Pacific voice against Climate Change and a maintainable and equitable ocean management for the region.

Matisse has a background in Public Relations and TV/Radio production, as well as a journalism degree, a powerful little blog, a few years as an international model and a history of standing up and speaking out.

She was introduced to Greenpeace at age 10 on the deck of the Rainbow Warrior, holding a home-made (glittered) poster reading “This is my home. Please don’t spoil it” in the middle of Suva Harbour.

“There is a paradise worth saving. It is not in the brochures. It is in the sticky mango hands, the salty hair, the outdoor naps, the island laughter, the grandmas and uncles and friends and children all around a bowl of fresh fish, taro and hand-picked chillies.

To do so, we need to make the hard decisions. To learn the difference between ‘can’t’ and ‘won’t’, what is ‘inconvenient’ and what is ‘impossible’.

That is why I work for Greenpeace. So my children’s children don’t have to live behind seawalls against an empty ocean.”

March 2015. Ian Lawton, Bequests Coordinator, Greenpeace Australia Pacific

Ian Lawton, Bequest Manager

Ian's first job was working as a youth worker on the streets of inner Sydney. He has always been passionate about bearing witness to injustice and supporting the underdog. He has worked for humanitarian organisations in Australia, New Zealand and America.

One of Ian's guiding principles is paying kindness forward. In early 2015, Ian joined Greenpeace to lead the Bequest (Legacy) program and is excited to support others as they show kindness to the earth and future generations by leaving gifts to Greenpeace in their Wills.

Ian is grateful and humbled by the many Greenpeace supporters he talks to on a daily basis. He is confident that together we can make a huge difference to the earth for a long time to come.
