Parks Victoria has announced that the Milanesia to Ryans Den section will undergo a track upgrade commencing Monday, 22 September.
Works are expected to take up to six weeks.
The track upgrade will include track regrading, widening and reforming, drainage, minor realignments and step-planking boardwalks.
The walk will remain open to walkers along these sections of track, however, at times there may be machinery on the track.
Signs and traffic controllers will be advising walkers of work areas that are being upgraded.
