Horsham Aerodrome is undergoing a major upgrade to ensure it can provide modern emergency services into the future.
Work includes runway pavement reconstruction, new guidance lighting and the installation of a new back-up power generator.
It follows a Civil Aviation Safety Authority review of the airport’s suitability to provide essential services including aeromedical transfers.
Horsham Rural City Council is managing the upgrades, contracting five Wimmera companies to complete the work during coming weeks.
