Retaining Walls Less than 2400 High AS1993
Retaining walls less than 2400mm high must comply as a standard barrier in regards to Non Climbable Zones. Other barrier elements may be needed to make them comply.
Retaining walls need to be looked at under the same scrutiny as any other barrier type. Non-Climbing Zones are an essential part of a retaining wall being compliant.
