Victoria's BushTender — Reverse-Auction Payments for Biodiversity Management

In 2001, the Victorian state government's Department of Natural Resources and Environment piloted BushTender, testing whether a competitive reverse auction could allocate conservation funding to private landholders more efficiently than a traditional fixed-price grant scheme. The AUD $400,000 pilot ran across two regions of Victoria, Australia, and was later extended to Gippsland before evolving into the broader EcoTender programme.

Landholders nominated native-vegetation sites, which government field officers scored for conservation value (a Biodiversity Significance Score) and for the improvement expected from proposed management actions such as fencing and weed and pest control (a Habitat Services Score). Landholders then submitted sealed bids stating the payment they required to deliver those actions under a multi-year management agreement, and bids were ranked by a Biodiversity Benefits Index combining site value, expected improvement and bid price, with government funding the most cost-effective bids until the budget was exhausted.

The peer-reviewed evaluation found the pilot secured 3,160 hectares under management agreement from 73 landholders, and estimated the auction achieved the same biodiversity outcome at roughly one-seventh the cost a fixed-price grant scheme would have required. A commissioned participant survey found bidders broadly representative of the trial-region landholder population by farm size, income and age.

The scheme paid for management inputs rather than verified ecological outcomes, shifting monitoring risk onto government, a design choice the original researchers themselves flagged, and it was designed and evaluated as a one-off pilot; the authors note a repeated, larger-scale auction could see landholders learn to anchor bids upward over time, eroding some of the cost savings. The original BushTender/EcoTender branding has since wound down as a standalone programme, though its auction methodology continues to underpin Victoria's successor catchment-based conservation tenders and biodiversity offset market tools.
