The Andrews government won't release its secret list of dangerously clad buildings despite revelations that another public building has been found to have flammable cladding.

The AFL and the City of Melbourne have confirmed flammable cladding was found on the exterior of Marvel Stadium late last year but they maintain the venue is safe for players, patrons and staff.

The AFL bought the stadium in 2016, 16 years after it opened. Construction began in October 1997 and at the time of its completion in 1999, the cladding was understood to be compliant.

However, late last year authorities identified non-compliant cladding on the exterior of the stadium.
