Woven Forms | Blair Athol & Kilburn Commissioned by the City of Port Adelaide Enfield
"The precinct of Blair Athol and Kilburn is a vibrant tapestry of cultures and nationalities. These oversized woven basket forms celebrate that diversity, using one of humanity’s oldest crafts as a metaphor for community.
Historically, basket weaving transcends any single society; it is a shared global language of trade, ceremony, and utility. Crafted from intertwined stainless steel rods, these sculptures represent the 'weaving' of individual stories, journeys, and dreams. While a single strand may be vulnerable, once interconnected, they form a bond of immense strength and unity—a reflection of the diverse community that defines this region."

Panpapanpalya | City of Port Adelaide Enfield A collaboration with Kaurna artist Paul Herzich
"Panpapanpalya is a collaborative public art installation created with Kaurna artist Paul Herzich. Made from weathered Corten steel, the sculpture features large rings that symbolize a traditional meeting place. It is a tribute to the enduring connection of the Kaurna people to this land and serves as a space for the community to gather, reflect, and connect.
Created in 2017, this three-meter steel and copper willow tree stands as a sanctuary for reflection and remembrance. The sculpture honors the lives of Greg, Caitlin, Willow, and Rosemary, whose lives were tragically lost in a road accident.
This was a true community project; the 'foliage' consists of thousands of copper leaves, each hand-stamped with messages of love and support by family, friends, and members of the public. Visitors are invited to step inside the canopy, where the light filters through these thousands of personal tributes, creating a space for quiet contemplation and enduring connection.
You may have seen trees painted blue on your travels. These are part of the Blue Tree Project an Australian mental health charity that began in 2018 after the tragic loss of a young man named Jayden Whyte to suicide. The project uses painted blue trees as a visual symbol to spark difficult conversations about mental health and remind people that it's okay to not be okay. The first blue tree was a prank Jayden painted on his family's farm in rural Western Australia.
I recently was given the privilege to design and make a sculpture base around this project for the Unley Council, located at Goodwood Oval after they lost members of their football club to suicide.
This piece is inspired by the Australian native Bottle Tree, This bulbous tree design being solid and strong is a metaphor for strength, to inspire hope, resilience and reflect the need for connection and awareness of mental health and to look out for those who are doing it tough.
The holes within the sculpture are a reminder to all of the community that may be affected by mental health in our lives, and those who love us and may need our help or friendship in times of need.
The two birds sitting on the nearby pole sculpture are perched together to further signify another metaphor for mateship and the need to share, listen and always support each other.
This sculpture is a reminder to check in on friends and love ones as well as reach out if you need support. See below Beyond Blue and Life Line.
Love and Peace to all
