Dredging alongside St Kilda Pier
Issued Monday 28 April 2025 at 12:00 pm
Dredging will start in early May and last for 2-3 weeks. This dredging is essential for safe navigation in the harbour for both commercial and recreational vessels. It also supplies sand for replenishing nearby beaches.
Dredged sand will be spread across the beach north of the pier. This freshly dredged sand may contain organic material, such as seaweed, which gives it a dark colour and mild odour. This material will naturally return to a normal colour and lose its odour after a few days.
Pipes are used to transport the sand and water from the dredge to the beach. Public access to this area will be restricted; the site will be fenced and supervised during operation.
