Silent auctions are a versatile fundraising tool used by charities, schools and organisations across Australia. But a common question from event planners is: can silent auctions be open to the public?
The short answer is yes, and it’s entirely up to the host. In fact, many organisers share digital bidding links via social media or email to boost reach and engagement.
Opening your silent auction to the public can dramatically increase participation and fundraising results, but it’s important to promote wisely. You want enthusiastic bidders who follow through, not unreliable participants who leave you chasing payments.
In this blog, we’ll walk you through how they work, the pros and cons and the strategies that keep things running smoothly.
Quick Overview: Can the Public Join Silent Auctions?
Yes, silent auctions can be open to the public, and many organisations choose this route to boost visibility and maximise bids. Whether you’re running an in-person event or a fully digital auction, opening access beyond your guest list can expand your reach and fundraising potential. Many hosts share bidding links on social media or email to draw in wider support.
But success comes down to smart planning. You’ll need a clear promotional strategy, reliable payment processes and a good read on your audience, so you’re not left chasing uncommitted bidders. And, of course, always make sure you’re following local fundraising laws and guidelines.
Let’s take a closer look at how it all works.
What Is a Public Silent Auction?
A public silent auction allows anyone to view and bid on auction items, not just ticketed guests or invitees. These auctions can be held:
- Online, accessible via a public link
- In person, such as at shopping centres, community festivals or open venues
- Hybrid, where both attendees and online participants can take part
Whether it’s a weekend event at a local hall or a digital auction hosted on a bidding platform, opening your auction to the public can create more engagement.
Benefits of Opening Your Auction to the Public
Opening your auction to the public comes with several advantages worth considering. Here are some of the key benefits.
Wider Reach
Allowing the public to participate increases the number of potential bidders, which often leads to higher competition and better fundraising outcomes. More participants mean greater bidding momentum and a higher likelihood of items selling above their estimated value. It also opens the door to supporters who may not have been on your original guest list but are still eager to contribute.
More Awareness
A public auction spreads the word about your cause, attracting new donors and supporters beyond your usual network. This increased visibility can lead to long-term donor engagement and future event participation. It also strengthens your brand presence in the community or online, depending on your auction format.
Flexibility for Guests
Online access allows people to participate on their own schedule. There’s no need to attend in person to support your event. This convenience increases participation from people with busy schedules or those living in different locations. It also makes your event more inclusive, especially for supporters who may have mobility or travel limitations.
Great for Local Business Promotion
Public events offer an opportunity to showcase donated items and services from local sponsors to a larger audience. This added exposure can strengthen sponsor relationships and encourage repeat donations for future events. It also shows your organisation’s commitment to supporting local businesses, which builds goodwill in the community.

Tips for Hosting a Public Silent Auction Successfully
A public auction requires additional planning to manage access, logistics and communications.
Choose the Right Format
- Online auctions are the easiest to open to the public.
- In-person events may need crowd management and signage.
- Hybrid auctions work well when paired with mobile bidding.
Use a Mobile Bidding Platform
This kind of platform makes public participation easy and secure:
- Public access via a shared auction link
- Real-time bid tracking and notifications
- No need to download apps or attend in person
Promote Your Auction Widely
Use social media, email newsletters, community notice boards and local media to spread the word. A multi-channel approach helps you reach a broader audience, including those outside your usual supporter base. Don’t forget to create a clear, engaging message with key details and a link to your auction platform to drive participation.
Set Clear Rules
Make sure your bidding process, auction end time and collection/payment policies are easy to understand and available to all. Clear rules prevent confusion and help create a smooth experience for both guests and organisers. Display this information on your auction website, printed materials, and at the event itself, so no one misses important details.
Considerations for Public Auctions
While public auctions can be highly effective, keep the following in mind:
- Registration & Verification: Require participants to register with a name, email and phone number to ensure legitimate bids and easy follow-up.
- Payment & Item Collection: Be clear about how and when winners will pay and receive their items. For remote bidders, offer shipping options or pickup points.
- Fundraising Compliance: Even for public auctions, you must follow any local fundraising and privacy regulations.
When to Keep Your Auction Private Instead
There are scenarios where a closed or private auction is more suitable:
- When auction items are exclusive to a ticketed event
- If you want to reward loyal supporters or members
- When the auction includes sensitive or high-value items best managed within a small group
