Frequently asked questions

Tender events are offered to registered participants. To complete a purchase and take a transfer of quota, the buying entity must hold a valid Synthetic Greenhouse Gas Licence (SGGL) permitting the import of HFCs under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. You do not need to provide the licence to register or to place a bid: Greenstar Climate Solutions Pty Ltd completes licence and eligibility checks before settlement, and may decline a registration or set aside a bid where verification cannot be completed.

Registration asks only for standard entity and contact details so the registering party can be identified. Three supporting documents can then be uploaded from your buyer profile: a copy of your Synthetic Greenhouse Gas Licence (SGGL) certificate, a current ASIC company extract issued within the last 3 months, and proof that your contact is authorised to act for the company (a letter of authority signed by a director or company secretary, or the contact appearing as an officeholder on the ASIC extract). All three are optional before bidding and can be provided before or after the auction, although providing them early helps us verify your registration sooner. Successful bidders complete verification before settlement, and the Process Letter sets out the documents required for any given tender event.

The reserve price is set by Greenstar Climate Solutions Pty Ltd as the seller of its own quota allocation, at its sole discretion. It is not disclosed to participants and is not published on this platform. A reserve operates as a minimum acceptable outcome for the seller: the seller is not obliged to accept any bid that does not meet it. No indicative or guide figures are provided, and participants should not infer a reserve from any material on this site.

Bids are submitted directly through the secure buyer portal on this platform before the published deadline. Once you are a verified participant, the Submit Bid page accepts your volume and price per tonne for either or both vintages on offer. You may improve your bid any number of times before the deadline: raise your price per tonne (for any volume) or increase your volume at the same price. A bid can never be lowered or withdrawn. If you raise your price for a smaller volume, your earlier bid remains binding for the remaining volume at its price. Once the deadline passes, your standing position is a binding, irrevocable offer. Where enabled for a tender event, the platform may display two private indicators back to you after each submission: a binary signal of whether your bid clears the reserve price, and your current rank for that vintage. Neither indicator reveals the reserve itself or any other bidder's price, volume, or identity. By default tenders run fully sealed and no indicators are shown.

Yes. When you submit a bid you make a binding, irrevocable offer to buy the nominated volume of HFC import quota at the nominated price. You can improve your bid until the published deadline, but a bid can never be lowered or withdrawn. If you raise your price for a smaller volume, your earlier bid remains binding for the balance at its price. Once the deadline passes your standing position is final. Greenstar Climate Solutions Pty Ltd is not obliged to accept any bid, including the highest, and a sale is formed only when a Sale and Purchase Agreement is executed. Any sale also remains conditional on verification of your eligibility and on approval of the quota transfer by DCCEEW.

Bids are ranked by price per tonne from highest to lowest. The highest-priced bid is allocated first, followed by the next highest, and so on until the available volume is fully allocated or all qualifying bids are exhausted. A bid does not need to cover the entire volume on offer: partial allocations are awarded at the submitted price. Any volume for which no bid meets the reserve price is not sold in that event and rolls over to the next scheduled tender.

Bids are ranked by price per tonne, highest first. Equal prices are tie-broken by the earliest submission time, which the platform records for every bid. A minimum bid increment applies when a new bid would take the leading position; the increment for each event is published with the tender details. Evaluation also considers the certainty of completion, including the extent of any conditions attached to the bid and the bidder's readiness to settle. The seller reserves the right to assess bids on these combined factors and is not bound to accept the highest price. The evaluation approach for each event is described in the Process Letter.

To prevent last-second outbidding being decided by network speed rather than price, any bid received within the published soft-close window of the deadline extends the deadline by the same amount of time. For example, a five-minute soft-close means a bid landing in the final five minutes pushes the deadline back by five minutes, and so on. The current and original deadline are both visible on the bid page. The soft-close window for each event is published with the tender details.

If your bid is not selected, you are notified that the tender has concluded without an award to you, and no transaction proceeds on that bid. Bid amounts are not disclosed to other participants at any stage. Unsuccessful participants remain registered and are eligible to take part in future scheduled tender events, subject to ongoing licence verification. Any materials provided during the tender remain confidential and subject to the terms under which they were released.

Form 35 is the DCCEEW instrument used to record a transfer of HFC import quota between licence holders. Once a sale is agreed, the parties lodge Form 35 with the Department to effect the transfer of the allocated volume. Completion of the sale is conditional on the Department's approval of that transfer. Approval timeframes are determined by the Department and are not within the control of the seller or the platform, so a specific duration is marked [TBC] and confirmed through the Department's own process.

Each sale is conditional on the Department approving the Form 35 transfer. If approval is refused, the transaction does not complete. In that event, the arrangements are unwound in accordance with the sale agreement, and any amounts held are dealt with as that agreement provides. The precise consequences of a refusal, including the treatment of deposits and the return of any funds, are governed by the executed sale agreement between the parties.

Yes. No participant can view another participant's bid amount, volume, or identity at any time, and no prices are ever published on this site. Where the live indicators are enabled for a tender, a participant sees only their own binary reserve-met signal and their own rank for that vintage, never another party's data. Bid evaluation is conducted privately after the deadline, and outcomes are communicated to each participant individually.

Greenstar Climate Solutions Pty Ltd does not charge participants any fees. Registration, access to the tender documents, question submission, and bidding are all free of charge. The only amount payable is the purchase price for the quota you are allocated: the volume you win multiplied by your bid price per tonne. The commercial terms for each event, including payment timing, are confirmed in the Process Letter and the Sale and Purchase Agreement.

Settlement is handled directly between Greenstar Climate Solutions Pty Ltd as seller and the successful bidder. On selection, the parties execute the Sale and Purchase Agreement, the Form 35 transfer is lodged with the Department, and completion follows the Department's approval of that transfer. The seller manages the sale process end to end so each transaction is ready for government approval, and would engage external legal support only if a particular transaction genuinely required it. Funds and the quota transfer are dealt with under the terms of the sale agreement, and the detailed settlement mechanics for each event are described in the Process Letter.
