Melbourne’s tallest building and major tourist attraction the Eureka Tower has been found to feature combustible cladding.

But the Victorian Building Authority (VBA) says the “small amount” of material does not pose a risk to safety.

The VBA carried out an audit of 170 Melbourne buildings and found 51% feature non-compliant material.

It followed a blaze in November 2014 at the Lacrosse apartments in Docklands, which was fuelled by cladding imported from China and not tested to Australian standards.

Following an “extensive investigation” the VBA has referred the Lacrosse building surveyor for disciplinary action by the Building Practitioners Board.

It alleges Anastasios Galanos breached the Building Act and Regulations, and failed to carry out his work in a competent manner and to a professional standard.

The VBA has also referred the architect to the Architects Registration Board of Victoria.

Its investigation into other Lacrosse building practitioners is continuing and should conclude in coming weeks.
