What is Lake Knox?

Lake Knox is a naturalised wetland in the heart of Knox, affectionately named by the many locals who value this large, deep-water body. Acting for the State Government, Development Victoria intends to fill in Lake Knox for a new blank canvas on which to meet stormwater requirements so that they can build medium-density housing developments onsite. The Development Victoria proposal would disturb and destroy the home of endangered species, for the mighty dollar once again.


The best place to see Lake Knox is via the Blind Creek Trail ->

*Please note that there is no public access to the lake as it is on government land.

Selling Off Threatened Habitat

The current proposal will see crucial deep-water habitat for the Blue-billed Duck lost. This duck is listed as endangered in Victoria, and the governments own action statement for the duck recommends ensuring important breeding sites are secured from further environmental degradation, and the protection, enhancement and restoration of key sites in parks, reserves and private land.

The planned wetland area to replace Lake Knox will see the current ecology trashed. The Blue Billed Ducks will not return to the site as they require a deep large body of water for their habitat requirements. The area of the lake will expand, but it will lose 10million litres (or 1/3) of its capacity. The deep water body that it is, will not be recreated, and what you'll end up with is just another “wetland” that will become polluted once further stormwater is directed into it.

Crowd-funded Professor Paul Boon Report

This report reviews the ecological values of Lake Knox and the likelihood that the new lake/wetland complex will adequately replace the foregone biodiversity and ecological values if Lake Knox were to be destroyed. Two expert reports now state that the Development Victoria proposal essentially seeks to ‘engineer’ away a problem through off the shelf design options that do not stand up under even limited scrutiny from an ecological/biodiversity/urban design point of view.

We wish to highlight that over 132 people contributed to a crowd funding campaign in order to pay for this report.

Review of proposal to drain Lake Knox & replace it with a constructed stormwater lake/wetland complex: ecological considerations by Professor Paul I Boon, Dodo Environmental, 18 September 2020



What are we doing about it?

First Friends of Dandenong Creek (FFDC), the Knox Environment Society (KES) and Friends of Lake Knox Sanctuary (FOLKS) have been campaigning for some time but the community are not being listened to, despite having a petition with over 13,000 signatures, having written many submissions and letters to various departments and politicians and engaging in several community "meetings". (See Update August 2020 for more info.)

Development Victoria's proposal will mean effective or functional loss of the well-established, existing aquatic ecosystem, alongside other losses in terrestrial native vegetation and potential habitat. It seeks to replace this vital asset with a relatively conventional complex of stormwater wetlands. Lake Knox currently supports a range of rare and endangered flora and fauna, including the iconic Blue-Billed Duck (endangered in Victoria) and the critically endangered Eel Grass in Knox (considered rare in Melbourne) (see full list below).

Development Victoria remains committed to seeing Lake Knox as an obstacle, unwilling to acknowledge reputable scientific assessments and advice that seeks to find a solution to conserve protect and enhance the life already abundant therein.

While we appreciate the redevelopment amounts to a complex urban infill project, with various considerations to take into account, the proposal does not yet provide a full and proper response to biodiversity and habitat considerations in this northern sector. Consequently, it does not favour a net community benefit and sustainable development.

Based on current legal advice from our lawyer, Dr Bruce Lindsay from Environmental Justice Australia, the proposal does not appear to be responsive to a correct assessment of legal and policy provisions and, as a result, it is not clear that the response proposed in the stormwater wetland complex is viable or optimal or both by Development Victoria. This view is further informed by key uncertainties evident in technical reports on which the proposal appears to rely, but not satisfactorily accounted for. These uncertainties exist alongside the fact of high value biodiversity, including both flora and fauna species, associated with the extant wetland and surrounding land.

That said, when legitimate concerns are being raised over the quality of information presented by Development Victoria, it must be treated with the utmost seriousness. Rightfully the community is not accepting Development Victoria’s position, having relentlessly sought appropriate audience with Development Victoria for the past two years, to no avail.
