Google Ads Updates for Australian Businesses: What to Review Before September Ends
If you're running Google Ads in Australia, now's a good time to log in and have a proper look around. We're in the last few days of September 2026, and Google keeps handing more of Search over to automation. A handful of changes landed this month too. You don't have to jump on every new feature. The real question is whether your tracking, your first-party data, your landing pages and your campaign controls are solid enough to keep all that automation heading where you want it.
Quick answer: Before 30 September 2026, check whether any of your Search campaigns have been upgraded to AI Max, save your performance numbers from before the upgrade, go through your search terms and the ad text Google's written, make sure your conversion tracking counts real leads, and look over your consent processes before you use the new IP address fields in Customer Match.
What Changed in Google Ads in September 2026?
For Australian advertisers, four things stand out:
- AI Max auto-upgrades. Eligible Search campaigns are being switched over to AI Max, and Google expects to finish by the end of September.
- A new AI Max report. It's been announced, but you can't use it yet.
- Customer Match changes. You can now upload IP addresses and interaction timestamps.
- Language targeting. Industry reports say manual language targeting is being pulled from Search campaigns.
AI Max for Search: What It Is and Who's Affected
What is AI Max?
AI Max isn't a new campaign type, even though it sometimes gets talked about like one. It's a set of AI features that sit inside a normal Search campaign:
- Search term matching puts your ads in front of relevant searches that aren't on your keyword list.
- Text customisation writes headlines and descriptions based on your existing ads and your website.
- Final URL expansion can send people to a different page on your site if Google reckons it's a better fit.
Your campaign IDs and performance history stay put through the upgrade, so you won't lose your data.
Which campaigns are being upgraded?
Two kinds of campaigns are affected: ones using the campaign-level broad match setting, and ones using Automatically Created Assets (now called text customisation). This part trips people up. Having broad match on individual keywords doesn't trigger the upgrade. It's only the campaign-level setting. Dynamic Search Ads aren't included either, because Google has pushed their automatic upgrade back to February 2027.
Your AI Max review checklist
- Find the affected campaigns. Check campaign settings and any notifications in your account.
- Save a baseline. Write down spend, conversion rate, cost per conversion, qualified lead rate and ROAS from before the upgrade. You'll want these for comparison later.
- Go through your search terms. Look for irrelevant queries, informational searches, competitor names and anything from outside your service area.
- Actually read the ad copy Google generated. Check pricing claims, offers and whether the tone sounds like you.
- Check your controls. Brand exclusions, negative keywords, locations and audience signals should still line up with your strategy.
The New AI Max Report: Useful, But Not Here Yet
Google's announced a single report that shows each search term next to the assets that were served and the page the person landed on. That's handy. But there's no release date yet, just a promise of more details later this year. So hold off on building any reporting process around it until you can see it in your account. And even when it turns up, better visibility doesn't mean you can stop checking spend and lead quality yourself.
Landing Pages and Creative: Give the Automation Good Inputs
AI Max learns from your website. That means vague or out-of-date copy on your site can end up in the ads Google writes for you.
- Match each landing page to what the person searching actually wants. Sending everyone to the homepage isn't a plan.
- Keep Final URL expansion on if your site is well structured. Think about limiting it where compliance or tightly controlled messaging matters.
- Keep login pages, staff profiles, expired offers and thin blog posts out of the mix.
Example: Say a Canberra business wants people searching "web design Canberra" to land on a dedicated web design page, with portfolio examples, clear service details and an enquiry form. What it doesn't want is those people ending up on a blog post from three years ago. Once Final URL expansion is on, going through your pages one by one stops being optional.
Fast, well-built pages also help your Quality Score and your conversion rate. If your site needs some work before any of this, a custom web development review is a good place to start.
Conversion Tracking: Show Google What a Good Lead Looks Like
Automated bidding goes after whatever you've told it counts as a conversion. If every brochure download counts as a win, guess what you'll get more of. Brochure downloads. So check that:
- Your primary conversions are real business goals, like purchases, qualified leads or booked consultations.
- Secondary actions are tracked separately, and there are no duplicate tags.
- Forms and call tracking are actually firing.
- CRM outcomes, such as closed sales, are imported wherever you can manage it.
Twenty good enquiries are usually worth a lot more than a hundred junk form fills.
Customer Match: New IP Address and Timestamp Fields
Customer Match uploads now accept User IP address and User interaction timestamp columns. The important bits:
- IP addresses and timestamps go up unhashed, unlike emails and phone numbers.
- You can't upload a timestamp without an IP address.
- IP matching doesn't work for users in the EEA, UK or Switzerland.
These fields might lift your match rates. But because the data isn't hashed, look over your privacy policy, collection notices and consent processes before you upload anything. If you're not sure where you stand under the Australian Privacy Principles, talk to a legal professional.
Search Terms, Locations and Budgets
When matching gets broader, the boring housekeeping matters more:
- Report on brand and non-brand performance separately.
- Double-check your location settings, whether you cover Canberra, the ACT, regional areas or the whole country.
- Keep an eye on daily and shared budgets for any surprise jumps.
- Measure success by cost per qualified lead, not clicks.
Paid search also does better when it's backed by a strong SEO service and steady social media marketing, since all three draw on the same first-party data and audience signals.

Frequently Asked Questions
What is AI Max in Google Ads?
It's a set of AI features inside Search campaigns: search term matching, text customisation and Final URL expansion.
Which campaigns are being upgraded to AI Max in September 2026?
Search campaigns using the campaign-level broad match setting or Automatically Created Assets.
Do broad match keywords trigger the AI Max upgrade?
No. Only the campaign-level broad match setting does. Keyword-level broad match is fine.
When will Dynamic Search Ads move to AI Max?
Google's scheduled the automatic upgrade to start in February 2027.
What's new in Google Ads Customer Match?
You can upload unhashed IP addresses and interaction timestamps now. A timestamp has to come with an IP address, and IP matching isn't available for users in the EEA, UK or Switzerland.
Why does conversion tracking matter more with automation?
Automated bidding learns from your conversion signals. If they're accurate, it moves towards qualified leads and revenue. If they're not, it'll happily chase cheap, low-value actions.
