Best Online Auction Software for Australian Charities (2026)
July 30, 2026
⚡TL;DR — The Short Answer
For an AU charity gala, the honest answer is usually a stack: an auction tool for the bidding, a ticketing tool for the door, and a donations tool for the appeal. Zeffy replaces that stack with one free platform.
Mobile bidding extends a one-night gala and lets supporters in other states participate without being in the room.
Auction winning bids are never tax-deductible in Australia because the bidder receives an item. Only cash donations of $2 or more to a DGR-endorsed charity qualify.
The AU gala and silent auction season peaks around EOFY (30 June) and the September to November spring window.
If you are running GalaBid + Humanitix + a separate donation form, Zeffy consolidates that stack for free.
Confirm your platform can issue a GST tax invoice if your charity is GST-registered before committing to a large event.
Online auctions are a powerful tool for Australian charities, community groups, P&Cs, and sports clubs, but the success of these events largely depends on the auction software used to run them. The right online auction software can streamline the bidding process, engage your supporters, and maximise your fundraising at a gala dinner, trivia night, school fete, or silent auction evening.
This guide walks through the essential features and considerations for choosing online auction software in Australia, from user-friendly interfaces to AU-specific receipting rules, so you can pick the right tool for your next fundraising event.
Online auction software is a digital tool for creating, managing, and executing auctions, whether fully online, mobile-based, or run live at a gala with bidders on their phones.
These platforms let organisations host auctions where supporters can place bids on items or services from anywhere across Australia and overseas, and they help automate many aspects of the auction process.
Core features of online auction software
User registration and authentication: Secure and straightforward sign-up processes for bidders and organisers.
Auction creation: Tools to list items, set starting bids, reserve prices, and auction timelines.
Bidding: Real-time bid tracking, automatic bid increments, and notifications for outbid alerts.
Payment processing: Integration with payment gateways to handle transactions securely. AU charities commonly use Stripe AU or similar; if your charity is GST-registered, ticketed event entry and auction winning bids require a tax invoice showing price and 10% GST separately (see the ATO's NFP hub for GST guidance).
Reporting and analytics: Insights into auction performance, bidder activity, and financial summaries.
Customisable interface: Options to brand the auction site to match your charity's look and feel.
A quick note on tax-deductibility in Australia
Auction winning bids and gala ticket purchases are not tax-deductible in Australia. The reason: the bidder or ticket buyer receives a benefit (the item, the ticket, the dinner), so the payment is not a gift. Only the excess of a payment above the fair market value of the benefit could be treated as a deductible gift, and only when your charity holds DGR endorsement from the ATO.
For auction items, issue a tax invoice (with GST broken out if you are GST-registered), not a DGR receipt. Only cash donations of $2 or more to a DGR-endorsed charity qualify for a tax-deductible receipt. Getting this right saves your committee from awkward post-event corrections.
What are the benefits of auction software?
Online auction software offers real advantages for not-for-profits, helping maximise fundraising and take the administration burden off your volunteers. It helps you:
Reach more supporters: Auction software lets charities reach donors across Australia and overseas, increasing the pool of potential bidders beyond the room.
Reduce costs and effort: Online auction software cuts the need for physical bid sheets, extra staff, and manual tracking. Many platforms automate administrative tasks, freeing up your team to focus on the night itself.
Maximise fundraising: Real-time bidding competition can drive up final amounts, and secure payment processing makes it easy for winners to pay promptly at the end of the night.
Collect and analyse data: Auction software captures valuable data on bidder behaviour and preferences, helping your charity plan future campaigns. Analytics on auction performance help you evaluate what worked.
Engage your supporters: Features like live bid feeds, outbid notifications, and mobile-friendly forms keep the energy up and encourage competitive bidding throughout your event.
When to run an online auction in Australia
Timing your auction well can meaningfully lift the result.
The AU charity gala and silent auction season has two natural peaks. The first is EOFY (the End of Financial Year, 30 June), when donors are thinking about maximising tax-deductible gifts before the financial year closes. An auction night in May or June rides this energy, even though the auction bids themselves are not deductible. A well-timed donation appeal at the end of the night, separate from the auction, can capture genuine DGR gifts. The second peak is the September to November spring window, when venues are available, the weather is pleasant for in-person events, and donor fatigue from EOFY has lifted.
Online and mobile bidding also solves a real problem for federated charities, those with state-based chapters (think RSPCA, Cancer Council, Vinnies), where supporters in other states cannot attend in person. An online auction with a QR code on every table lets a Melbourne supporter bid on items at a Sydney gala, extending your bidding base without a second event. Explore our charity gala planning guide and silent auction item ideas to get started.
Top online auction software for Australian charities
The platforms below are the tools AU charities and community groups actually weigh when planning a gala, school fete, or silent auction. The comparison focuses on AU-native options and platforms with real AU presence. Fees are verified against live AU pricing pages at the time of writing; confirm current pricing before you commit, as fees do change.
For the typical AU charity running a gala, that means replacing the GalaBid + Humanitix + separate donation form stack with a single platform. No juggling three logins on the night, no stitching together three post-event reports.
Pricing:
Zeffy is completely free for charities. When someone donates through your form, they have the option (but are never required) to leave a contribution to Zeffy. Enough supporters do so to cover every fee, meaning your charity keeps 100% of what it raises.
GalaBid is the AU-native specialist for charity galas and silent auctions. Founded in 2011 and part of the CrowdComms group, it has an Australian office in Sydney and a strong track record with AU charities including Camp Quality, Ronald McDonald House, Variety, Redkite, and Children's Medical Research Institute.
Pricing:
Free to start, with paid plans for advanced features. GalaBid also offers no-risk consignment auction items (your charity only pays if the item sells). Confirm current tier pricing at galabid.com before your event.
Features:
Silent and live auction support: mobile bidding from the table, paddle raise for live moments, and real-time impact tracking on a big screen.
Consignment items: access to donated items for auction without upfront cost.
Event ticketing integration: manage the door alongside the auction.
Stripe payment processing for secure checkout.
Honest take: GalaBid is purpose-built for one night a year, and that is exactly where it shines. It is the go-to for a larger charity gala where the committee wants a polished mobile-bidding experience and a big-screen results feed. Outside of events, it offers little for ongoing donations or donor management. Worth pairing with a separate donations tool for the appeal at the end of the night, unless you are using Zeffy for the whole event.
Humanitix
Humanitix is an AU-native not-for-profit ticketing platform (registered as a Public Benevolent Institution with the ACNC since 2017), founded in Sydney. It donates 100% of its profits from booking fees to charity partners focused on education, health, and indigenous scholarships. Used by Cancer Council NSW, Vision Australia, AFL clubs, and many AU community events.
Pricing (AU NFP rate):
2.5% + $0.50 per paid ticket. Free tickets are free. Standard rate (non-NFP) is 4% + $0.99 per paid ticket. Confirm current pricing at humanitix.com/au/pricing.
Features:
Event ticketing with accessible, mobile-friendly checkout.
NFP-discounted rate for registered not-for-profits.
Booking fee goes directly to charity partners.
Integration with Stripe for payment processing.
Honest take: Humanitix is not an auction platform. But many AU charities run a gala on Humanitix for ticketing and then bolt on GalaBid for the silent auction, which is exactly the kind of fragmented stack Zeffy is designed to replace. The "profits to charity" mission story resonates with donors and committees alike, and the NFP rate (2.5% + $0.50) is meaningfully lower than Eventbrite. Worth considering if your primary need is ticketing a large public-facing event where discoverability matters. For a private charity gala with a known donor list, Zeffy handles ticketing and the auction in one free platform.
TryBooking
TryBooking is an AU-founded, AU-hosted event ticketing platform operating since 2010. It is the default ticketing tool for a large share of AU schools, community theatres, and regional events, and it leads with a strong data-residency message (data hosted in Australia, PCI compliant, no marketing of your attendees to other events).
Pricing (AU):
$0.50 per paid ticket (charged to the buyer by default), plus a 2.5% processing fee charged to the organiser (can be passed to the buyer). Free for free events. Confirm current pricing at trybooking.com/pricing.
Features:
Simple, low-fee event ticketing suited to schools, P&Cs, community groups, and regional events.
Data hosted in Australia (Safer Technologies for Schools certified).
No marketing of your attendees to other event organisers.
Accessible checkout, including school-payment-friendly options.
Honest take: TryBooking is the practical, low-fuss choice for a P&C trivia night, a school fete, or a community theatre. It wins on familiarity and AU data residency. Like Humanitix, it is a ticketing tool, not an auction platform, so you would still need a separate silent auction tool on the night. The same consolidation case applies: Zeffy's free platform covers ticketing and the auction together.
What should you look for in silent auction software?
Choosing the right auction platform shapes the experience for your committee, your volunteers, and your supporters on the night. Here are the key features and considerations for AU charities:
Ease of use: The software should have an intuitive interface for both administrators and supporters. Your volunteers should be able to manage it on the night without a manual.
Mobile compatibility: Ensure the software works seamlessly on mobile devices. In AU, most gala bidding happens on phones, not paper silent auction bid sheets, though paper sheets remain practical for small school fetes.
Item tracking: Track the status and bidding history of each item, including items with no bids so volunteers can encourage participation.
Real-time bidding: Ensure the software provides real-time updates so supporters see the current highest bid instantly.
Automatic bid increments: The software should automatically increase bids by a set amount, removing the need for manual management.
Max bidding: Allow supporters to set a maximum bid, with the system automatically increasing their bid up to that limit.
Outbid notifications: Send automatic notifications when a supporter has been outbid, keeping them engaged and encouraging return bids.
Integrated payments: The software should support secure credit and debit card payments and other payment methods common in Australia. A streamlined checkout process for auction winners reduces friction at the end of the night.
Auction reports: Detailed reports on bidding activity, item performance, and overall auction results help you review the night and plan the next one.
Branded auction pages: Customise auction pages with your charity's branding, including logo, colours, and theme.
Customer support: Reliable support via phone, email, or live chat, plus training materials and onboarding help to get your committee up to speed.
CRM integration: The ability to connect with your existing donor management system for seamless follow-up after the event.
Scalability: Ensure the software handles your auction size, whether you have a dozen items at a school fete or hundreds at a large gala.
Affordability: Consider the full cost, including transaction fees, against your event budget. Free platforms like Zeffy are worth evaluating first.
GST-ready tax invoicing: If your charity is GST-registered, the platform (or your finance workflow) must produce a tax invoice showing the price and the 10% GST separately for auction items and ticketed entry. Confirm this before you commit to a platform for a large event (see the ATO's NFP guidance for detail).
Data residency and Privacy Act fit: If your platform stores bidder details offshore, check it meets Australian Privacy Principles (APP) obligations. Post-Pareto Phone breach, OAIC guidance is 'collect only what you need'. AU-native platforms lead with this message; foreign platforms should be able to explain their APP compliance clearly.
Planning and running an effective silent or live auction for your charity does not have to mean juggling three separate platforms. With the right approach and the right tools, your organisation can run a great auction night without the administrative headache.
For most AU charities running a gala, the current reality is a fragmented stack: GalaBid for the silent auction, Humanitix or TryBooking for the door, and a separate donation form for the EOFY appeal at the end of the night. Zeffy's free online auction software consolidates that into one platform, covering mobile bidding, automated outbid notifications, easy checkout, donor management, and post-event thank-you emails, all at no cost to your charity.
Your supporters keep their focus on bidding. Your volunteers keep their focus on the room. And your charity keeps 100% of what it raises.
Some platforms offer free tiers. Zeffy is completely free for charities and not-for-profits, with no platform fee and no transaction fee. Other AU-native platforms like GalaBid offer a free-to-start model with optional paid upgrades for advanced features. Platforms like Humanitix and TryBooking charge per-ticket fees for ticketed events, but do not charge a platform fee for charities.
No. Auction winning bids are not tax-deductible in Australia because the bidder receives an item in exchange for their payment. Only cash donations of $2 or more to a DGR-endorsed charity qualify for a tax-deductible receipt. For auction items, issue a tax invoice (with GST separated if your charity is GST-registered), not a DGR receipt. For more detail, see the ATO NFP hub and the ACNC DGR fact sheet.
In a silent auction, supporters browse items and place bids (on paper sheets or via a mobile app) at their own pace during the event. Bidding closes at a set time, and the highest bid wins. In a live auction, a professional or volunteer auctioneer calls bids in real time and the audience competes openly. Many AU charity galas run both: a silent auction during the drinks and dining portion, followed by a live auction for the headline lots. Mobile bidding software like Zeffy or GalaBid works for silent auctions; live auctions can also use the same platform for checkout.
Start with your auction items and a clear closing time. Choose a platform that handles mobile bidding, outbid notifications, and post-event payment collection. Set up your item listings with images, starting bids, and bid increment amounts. Promote the auction to your supporter list before the event and display a QR code on the night so guests can bid from their phones. After bidding closes, the platform collects payment from winners automatically. Follow up with a thank-you email and, where supporters also made a separate cash donation, issue a DGR receipt if your charity is DGR-endorsed. See our charity gala planning guide for a full checklist.
Yes. Zeffy supports charities and not-for-profits in Australia, offering auctions, event ticketing, donation forms, membership management, and donor management, all on one free platform. Zeffy issues tax-deductible receipts for eligible cash donations, helping DGR-endorsed charities handle post-event donor receipting without manual paperwork. There are no platform fees or transaction fees for your charity, ever.
GalaBid is an AU-native silent and live auction platform purpose-built for charity galas. It is excellent for a polished one-night event with mobile bidding and a big-screen results feed. The key difference is that GalaBid is primarily an event-night auction tool, whereas Zeffy is a broader fundraising platform that covers auctions, ticketing, donations, and donor management year-round, all for free. Many AU charities use GalaBid for the auction and a separate platform for ticketing and donations. Zeffy consolidates all of that into one place.
