It is hoped the $38,100 contemporary ceramic mosaic on the wall at Brighton Beach will bring colour to the area, which has been the focus of Wollongong City Council upgrade works in recent years.

The work is due to be finished this week and officially unveiled within about a month.

It is called Sirens of Woolungah and is a collaboration between Illawarra Koori artists Lorraine Brown and Narelle Thomas and Wombarra artist Michael Keighery.

Mosaic specialist Terry Cook, of Engadine, is also assisting.

Keighery said the project had taken about 12 weeks, including six days set aside for installation.

The artwork includes a stainless steel frame laser etched with European and Aboriginal design by Unanderra company Marciano.

There will also be interpretations of Aboriginal stories about the creation of the Five Islands and images from European mythology like Ulysses and Sirens.

"It acknowledges the difference and diversity of the area," Keighery said.

The council's director of corporate, community and cultural services Illana Halliday said the artwork was commissioned by the council as part of the Blue Mile project.

"The Sirens of Woolungah reflects Wollongong's rich history.

"The artists have done a terrific job linking the project with council's public artwork principles, reflecting the natural environment and the city's social history," Ms Halliday said.
