Australasian Marine Associates via Dredging Today; Campaign B image, not Campaign C, measured quantity or acceptance evidence

Victorian contract record 193674 identifies Australasian Marine Associates as supplier on ITS2-00225, displays a fixed-value AUD 1,939,850 portal total, records 8 September 2021 as the start date and labels the contract Current. Parks Victoria's 2024 navigation notice separately names AMA for Lower Yarra Campaign C from 13 March to 24 June 2024 across the Main Yarra Trail, VRA Landing, Herring Island, Southbank and Charles Grimes Bridge reaches. The 2024-25 Yarra Strategic Plan annual report says Parks Victoria's 2022-24 dredging programme was completed in 2024, but that programme statement does not establish contract closeout, final spend, accepted quantities or post-dredge survey results.

Project anatomy

Contract scope and delivery roles

Client / authority
Parks Victoria, waterway manager for the Lower Yarra River upstream of Port of Melbourne waters
Delivery parties
Australasian Marine Associates Pty Ltd - supplier named on Buying for Victoria contract ITS2-00225 and contractor named by Parks Victoria for Campaign C, Campaign-specific survey, monitoring, pipeline, support-vessel and plant lower tiers - not publicly disclosed
Contract route
Buying for Victoria contract record 193674 identifies ITS2-00225, names Parks Victoria and Australasian Marine Associates, displays a fixed-value AUD 1,939,850 total, records 8 September 2021 as the start date and labels the contract Current. Award or signing date, end date, extension structure, guaranteed minimum, certified payment ledger and final spend remain unpublished.
Execution window
The portal start date is 8 September 2021. Secondary trade reporting places Campaign B in April 2022. Parks Victoria's statutory Campaign C notice covers 13 March to 24 June 2024. The Yarra Strategic Plan annual report says the 2022-24 programme was completed in 2024, while the procurement portal remains Current. These dates describe different legal, campaign and programme boundaries.
Works package
Parks Victoria's Campaign C notice describes maintenance dredging to reinstate functional depth at floating trail sections, VRA Landing, Herring Island Meander and Southbank Floating Landing, plus the Charles Grimes Bridge channel. It also identifies in-river discharge areas near Herring Island and upstream of Bolte Bridge, moving exclusion zones, transit lanes and temporary closures. Secondary trade reporting says Campaign B used pipeline transport to a deeper river section upstream of Bolte Bridge; it does not prove the same method or quantities for every campaign.
Marine interfaces
A busy tidal urban waterway with commercial and recreational traffic, fixed and floating landings, narrow transit lanes, 5-knot controls, moving exclusion zones, temporary closures, berthing access, pipeline or discharge interfaces, water-quality monitoring and coordination with Port of Melbourne waters downstream.
Commercial evidence boundary
AUD 1,939,850 is the fixed-value total displayed by Buying for Victoria, not verified final spend, accepted production, guaranteed minimum or final account. Programme completion in the annual report is not evidence that the portal contract is administratively closed or that every campaign quantity and depth has been accepted.

Annual report separated completed programme from ongoing need

The 2024-25 Yarra Strategic Plan report says the 2022-24 programme was completed in 2024, estimates ongoing maintenance at about AUD 1.2 million per year and records a funding bid for the next two-year programme. It does not confirm that funding was awarded.

Source

Parks Victoria's Campaign C navigation-control period ended

The statutory notice names AMA and defines dredging, disposal and vessel-control locations through 24 June 2024, but does not publish quantities, post-dredge depths or acceptance.

Source

Campaign B delivery was publicly described

Trade reporting placed AMA from Bolte Bridge through the CBD and described pipeline transfer to a deeper in-river placement area. This secondary record does not establish owner acceptance or final production.

Buying for Victoria contract start date
