Checkout in Australia

Key Takeaways

  • In June 2026 Google made Australia the first Asia Pacific market for its Universal Commerce Protocol (UCP), the standard behind buying inside Google Search, AI Mode and the Gemini app. Kogan, Bunnings, Adore Beauty, Petbarn and The Iconic went first.
  • Smaller stores can't switch it on themselves yet. Google says its Merchant Center onboarding for UCP is rolling out in the U.S. first, "with Australia and Canada to follow next year".
  • OpenAI went the other way: in March 2026 it scaled back Instant Checkout in ChatGPT, letting merchants use their own checkout while it focuses on product discovery.
  • So the useful work this month isn't a checkout integration. It's making sure agents can read your products: price and stock in your product markup, a sitemap that lists product pages, and robots rules that let AI search crawlers in.
  • Blocking an AI training crawler and blocking an AI search crawler are separate decisions. Only the second one hides you from AI shopping answers.

Google's AI shopping checkout has reached Australia, but only for a handful of large retailers so far. On 17 June 2026 Google named Australia the first Asia Pacific market for its Universal Commerce Protocol, starting with five big retailers, and Google's own help centre says self-serve onboarding for Australian merchants follows next year. For a small WooCommerce or Shopify store, the job this month is making your products easy for AI agents to read. Here's what launched, what it means, and a checklist you can work through in an afternoon.

What did Google launch in Australia?

On 17 June 2026, at its Google Marketing Live event in Sydney, Google said Australia would be the first country in Asia Pacific to get its agentic shopping technology [1][2]. The launch partners were Kogan, Bunnings, Adore Beauty, Petbarn and The Iconic [1].

Two things were announced together:

  • A checkout inside Google. Shoppers can buy single items from participating retailers directly in Google Search, including AI Mode, and in the Gemini app [2].
  • An intelligent cart. Items added to it are tracked for price changes and back-in-stock alerts, and Adrian Vallelonga, Google's head of performance solutions for Australia and New Zealand, said "you can buy directly on Google or take your cart to the merchant site" [1].

Underneath both sits UCP, an open standard Google built with retail and payments partners so AI agents and stores can talk to each other without a custom integration for every pair [3].

A month earlier, Google had said UCP-powered checkout would "roll out across Canada and Australia in the coming months" [4]. The June launch was the first step of that rollout, with big retailers who could build the integration directly.

Can a small store sell through it yet?

Not through a self-serve button, at least not yet.

Google's Merchant Center help page for the UCP integration hub says it "is gradually rolling out in the U.S., with Australia and Canada to follow next year" [5]. The hub is where a merchant chooses capabilities such as cart transfer to their own site, checkout on Google, and identity linking [5]. Until it arrives here, Google describes UCP checkout as "available for select merchants", reached through a technical integration and an interest form [6].

What that means by platform:

  • Shopify stores already have a setting for AI channels. In the admin under Sales channels, Agentic, Shopify lists ChatGPT, Google AI Mode and Gemini, Microsoft Copilot, Meta and the Shop app, and by default lets Shopify manage access for you [7]. Among other requirements, products need a title, at least one image, a price above zero and a published product URL to qualify for Shopify Catalog [8].
  • WooCommerce stores have no equivalent switch from Google today. The work that pays off now is the groundwork in the checklist below.

What are UCP and ACP?

They are the two open standards competing to let AI agents shop on a person's behalf.

UCP (Universal Commerce Protocol) is the one behind Google's launch. Its specification covers the whole journey: searching a catalogue, building a cart, checkout, linking a shopper's account, and order updates [3]. A store that supports it publishes a profile at /.well-known/ucp on its own domain that tells agents what it can do [14].

ACP (Agentic Commerce Protocol) was developed by Stripe and OpenAI and powered ChatGPT's Instant Checkout [16]. It is open source under the Apache 2.0 licence [9]. Unlike UCP, a merchant's ACP status isn't visible from the outside: you apply and send OpenAI a product feed, so nobody looking at your website can tell whether you're enrolled.

For a small store, the practical difference today is that neither is something a WooCommerce store can switch on in an afternoon, while on Shopify, Shopify manages the AI channels for you by default. What both have in common is that they read the same underlying product data you already publish.

What changed when ChatGPT pulled back from in-chat checkout?

In March 2026, OpenAI scaled back Instant Checkout, the feature that let people buy inside ChatGPT. On 24 March 2026 OpenAI said "the initial version of Instant Checkout did not offer the level of flexibility that we aspire to provide", and that it would let merchants use their own checkout while it focuses on product discovery [15].

The coverage pointed to familiar retail reasons: people researched in ChatGPT but often didn't complete the purchase there, and retailers wanted to keep their own checkout, loyalty programmes and customer data [10][11].

For an Australian store, the lesson is reassuring. AI tools are increasingly where shoppers start, but the purchase still tends to happen somewhere the shopper trusts, and for most small brands that's your own site. Being found and described accurately by AI is the part you can influence now. Winning the sale on your own checkout is the part you already own.

What can a shopping agent read about your store?

Mostly the same things a search engine reads: your product pages, the structured data inside them, your sitemap and your robots.txt file.

Structured data matters most. Google's merchant listing documentation requires a product name, an image, and an offer with a price and currency, and recommends availability, brand, a product identifier such as a GTIN, ratings, and shipping and returns details [12]. If your price or stock status only appears as text on the page, an agent has to guess. If it's in the markup, it doesn't.

Both platforms produce some of this for you. WooCommerce and Shopify themes generally output product structured data, but the exact fields vary by theme and plugin, so check a real product page rather than assuming.

Your sitemap tells agents which product pages exist. Your robots.txt tells each crawler whether it may visit. A store with perfect markup that blocks the wrong crawler is invisible to it.

Should you block AI crawlers?

It depends which ones, because they do different jobs.

OpenAI documents its crawlers separately. Among them, OAI-SearchBot surfaces websites in ChatGPT's search features, GPTBot crawls content that may be used to train its models, and ChatGPT-User fetches pages when a user asks ChatGPT something [13]. OpenAI says each setting "is independent of the others", so you can allow search while blocking training [13].

That gives you two separate decisions:

  • Training crawlers (such as GPTBot or CCBot). Blocking them is a decision about whether your content trains AI models. It's yours to make, and it's not a visibility mistake.
  • Search crawlers (such as OAI-SearchBot, PerplexityBot, Claude-SearchBot and Bingbot). Blocking these removes your pages from the answers those tools give shoppers.

ChatGPT-User is neither. It only visits a page when a person asks ChatGPT to, OpenAI says robots.txt rules may not apply to it, and it doesn't decide whether you appear in ChatGPT search [13]. To control search visibility, set rules for OAI-SearchBot.

If you use Cloudflare or a security plugin with a one-click "block AI bots" option, check which category it blocks. It's easy to block search crawlers by accident while trying to opt out of training.

What should a small store check this month?

Six checks, most of them under ten minutes each:

  1. Open one product page's structured data in Google's Rich Results Test. Confirm the name, image, price, currency and availability are present and correct.
  2. Check identifiers. If your products have barcodes, add them: WooCommerce has a GTIN field in the product's inventory settings, and Shopify has barcode fields on each variant.
  3. Read your robots.txt (yourstore.com.au/robots.txt). Make sure search crawlers like OAI-SearchBot and Bingbot aren't disallowed, whatever you decide about training crawlers.
  4. Open your sitemap and confirm product pages are in it.
  5. Fill the gaps in your catalogue. Products with no image, no description or no price are the easiest for an agent to skip.
  6. On Shopify, open Sales channels, Agentic and decide whether to keep the default managed setting or control each channel yourself.

None of this depends on Google's timeline. It makes your store easier to read for every AI tool, and for ordinary search too.

What can nobody tell you from outside your store?

Whether an AI will recommend you. That depends on each tool's own ranking, which nobody outside can see, so be wary of any report that claims to know.

What can be measured from outside is whether you publish the signals agents read. For stores connected to QuackChat, our team can run an agent-readiness check on request that looks at four areas: the agent discovery file, retrieval permissions in robots.txt, product page markup, and catalogue data. It follows a few strict rules:

  • Unknown is never a fail. If your robots.txt can't be reached or a security check blocks our request, that item is marked unknown and left out of the score entirely.
  • Training crawlers are reported, not scored. Blocking them is your rights decision, not a defect.
  • ACP enrolment is never guessed. It isn't visible from outside, so it's shown for information only.
  • A missing discovery file is counted once, not repeated across every check that depends on it.

The result is a short report of what passed, what failed, and what couldn't be measured.

Where does a store assistant fit in?

At the last step, on your own site.

If AI tools increasingly send shoppers to merchants' own checkouts, the final questions ("is this in stock in black?", "will it arrive before the weekend?", "what's your returns window?") get asked on your product page. QuackChat's assistant answers stock and price from your live WooCommerce or Shopify catalogue rather than from a crawled copy, and delivery and returns from your own pages. If the store connection fails, it declines product questions instead of guessing. Shoppers add items to their own cart with a tap; the assistant never adds anything on its own, and the shopper's real cart stays in their own browser, on your site.

Try it on our demo store, or read how it works with WooCommerce and Shopify. The e-commerce page has the overview.

Frequently Asked Questions

Is Google's AI checkout available in Australia?

Yes, for a small set of launch retailers. Google named Australia its first Asia Pacific market for UCP in June 2026, starting with Kogan, Bunnings, Adore Beauty, Petbarn and The Iconic. Google says self-serve onboarding through Merchant Center reaches Australia next year.

How can a small Australian store get into Google's AI checkout?

Today, through a technical UCP integration and Google's interest form, as the feature is limited to selected merchants. Shopify stores can also manage AI channel access under Sales channels, Agentic. For most small stores the better use of time now is clean product data.

What is the difference between UCP and ACP?

UCP is the open standard behind Google's agentic checkout. ACP was developed by Stripe and OpenAI for ChatGPT. Both let AI agents act on a shopper's behalf, and both rely on the product data your store publishes.

Can you still buy inside ChatGPT?

OpenAI scaled back Instant Checkout in March 2026 and now lets merchants use their own checkout, while ChatGPT focuses on product discovery.

Will blocking GPTBot stop ChatGPT recommending my store?

Not on its own. OpenAI says GPTBot is for training and OAI-SearchBot is for ChatGPT's search features, and each robots.txt setting is independent. Blocking GPTBot while allowing OAI-SearchBot keeps you eligible for search.

Does QuackChat add products to a shopper's cart through AI?

No. The shopper taps Add to Cart themselves, and the item goes into their own cart on your site.
