The Kirra sand dredge was moored at the Inverloch jetty for repairs.

THE Kirra dredge began dredging in Anderson Inlet again today (Friday) after a 10-day break for repairs to the pump.
Dune reconstruction works on the Inverloch foreshore were originally due to be completed by June 30 but started late and encountered early teething troubles.
The latest breakdown has put the project at least a month behind, but the project team has confirmed that Hall Contracting will remain on site to complete the job in accordance with the design specified by Water Technology.

The company will cease 24/7 operations and move to a 12-hour daytime schedule for the remainder of the project, which will be a relief to some nearby residents who were disturbed by the nighttime noise.
Philip Heath, leader of the conservation society’s Coastal Resilience Project, said the June weather conditions were favourable with moderate tides, northerly winds and low to moderate swells dominating.
So far, around 70,000 cubic metres of pumped sand has been stockpiled on the beach, with another 30,000 cubic metres to be delivered.

Work started just west of the Ozone Street access track at the start of June and the renourishment reached the Surf Club on July 1. Shaping will continue progressively, as pumping to each compartment is completed.

Drone photos supplied by the South Gippsland Conservation Society show substantial reshaping of the beach, with teams working round the clock to backfill the reconstructed dune formed in line with the project design.
However, Mr Heath said the most challenging sections remain, with the design specifying a wider width of renourishment (more than 60 metres adjacent to Wreck Creek – North Arm), and taking account of the lower existing beach levels at the extent of the works between the Surf Club and the Cape Paterson Road rock wall.
Some pumped sand is likely to be lost during construction of this section, with several higher tides predicted during July, and weather conditions could change.
DEECA says some sand movement and loss is expected over time, as part of a dynamic coastal environment, but planned revegetation will help stabilise key areas and support the effectiveness of the reconstructed dune over the longer term.

Once sand pumping and shaping is completed, the dunes will be left to settle and allow salt to be leached from the upper levels by rainfall.
The conservation society is liaising with DEECA and Bass Coast Shire Council on the planting, which is expected to start in late spring. The Wonthaggi Seedbank and Barb Martin Bushbank native plant nurseries are propagating a range of species to be ready for planting at this time.
The plants will help to stabilise the reconstructed dunes by reducing wind erosion, trapping sand to build dune structure and providing habitat for native fauna, partially replacing what has been lost over the past 12 years.
