Dudley Siviour is a Metalwork teacher who studied sheetmetal, artmetal and design at Western Teachers College in the early seventies.

In 2000 he started working with corrugated iron as a low cost material to construct sculptures with a group of disinclined students. Members of staff and the local community were impressed with the results and bought many of the sculptures. The funds raised were used by students to buy parts and motors for go-karts that were constructed in classes.

His classes work was featured in an article in the education Department's Xpress newspaper in August 2001. Journalist Shirley Stackhouse, on seeing some of the works in a garden in Hay NSW, wrote an article about the students work in the Sydney Morning Herald "Domain" supplement.

KESAB's Ross Swain encouraged Dudley to enter his student's work into the KESAB Environment Awards, which they won in the school category that year. For the next three years KESAB featured a display of the sculptures at their Tidy Towns Awards presentation day at AAMI Stadium.

Dudley made trophies for many of their awards during that time, including the Beach Care Award perpetual trophy, featuring a Leafy Sea Dragon in stainless steel. In 2007 he took 6 months leave to develop more designs in both corrugated iron and stainless steel and began to sell them through Ruston's Roses and several outlets in South Australia.

Dudley has exhibited his works in the 'Our Changing Times' sculptural Art Exhibition at Ruston's Rose garden in 2007 and 'A Change of Art, artwork of Riverland teachers and students' as part of the 2008 SALA Festival.

He retired from teaching at the end of 2008 to focus on his sculpture work.
