READ NOWShe has been taking part in the Castaways awards since it started in 2008 and said it was getting bigger, better and harder to enter.
“I just love it because you have to use recycled components, which makes it a bit more interesting and you get to use different materials,” she said.
“I had to find a lot of aluminium cans to cover both sides of the silhouettes.
“I like the shiny surface reflecting on memories.”
A total of 38 sculptures will be on display from October 22 to 30, based on an aluminium theme.
Works in the exhibition this year range from large scale to small, and from literal interpretations to pieces that are poetic and fun.
Rockingham Mayor Barry Sammels said this year’s awards offered another wonderful opportunity to bring the foreshore alive with sculptures, while also highlighting the importance of recycling and environmental awareness.
“The event highlights the City’s strong commitment to recycling and its growing reputation as a centre of cultural activity,” Cr Sammels said.
One of the larger pieces on display will be a huge four-metre aluminium can, made from hundreds of aluminium cans, concealing a printmaking studio.
In another work, strings of aluminium cans reveal a lullaby, with the letters painstakingly hole-punched into the cans, which are lit in the evenings with LED lights.
Cr Sammels said visitors could join in the fun this year by attaching colourful tags to Message on a Bottle, a two-metre high bottle made from fencing wire commissioned by the City of Rockingham and created by participating artist Greg Gelmi.
Sculptures created by primary and secondary schools will feature in the schools exhibition, which is held as part of the main exhibition.
