Almost 30 years after it was created, Australia’s last-surviving large-scale Keith Haring mural has been unveiled after it was restored to its former glory by Italian conservator Antonio Rava.

The last surviving large-scale Haring mural in Australia, it was painted on the wall of the former Collingwood Technical College in 1984.

Haring died in 1990 of AIDS-related complications. His mural was added to the Victorian Heritage Register in 2004.

Unveiling the restored work on Sunday, Ms Victoria described the work on the mural, one of only 31 known Haring murals worldwide, as "quite remarkable, bringing back the colours and original line work".
