AI Overviews now trigger on 37.8% of Australian search queries, above the global average, and the click-through collapse behind that number is measurable in Search Console today. Part two of a four-part series on AI search in Australia: the data on what's actually happening to Australian clicks.
The whole results page got quieter. Not just the top listing. Every position on it.
The Take: Rankings and impressions still look fine on most Australian dashboards. The click behind them does not exist anymore. Nearly two in five searches here now return an AI Overview, and the businesses still budgeting off last year's traffic model are about to find out the hard way.
Most of the AI-search coverage you have read is American. Fair enough, most of the studies are. But Australia is not a bystander in this shift. It is ahead of it. This piece is the numbers, specifically ours, so you can see the scale of what changed before you decide what to do about it.
How Many Australian Searches Trigger an AI Overview Right Now?
An analysis of 116,918 Australian search results found AI Overviews now trigger on 37.8% of domestic queries, above the global average. That is more than one in three searches answered on the page before anyone reaches a website.
AI Overviews now trigger on 37.8% of Australian search queries, above the global average, based on an analysis of 116,918 domestic results.
That number comes from Safari Digital's analysis of Australian search results, and it lands on top of a market where Google already runs about 94% of search. There is no second search engine to route around this. When the dominant channel changes its own results page, every Australian business that depends on organic is exposed at once.

What Happens to the Click Once an Overview Appears?
It does not just soften. Ahrefs re-ran the numbers on December 2025 data and found the top-ranking page loses 58% of its clicks once an AI Overview shows up, nearly double the 34.5% drop the same study measured eight months earlier in April 2025. Position two loses about half its clicks. Even position ten, the bottom of page one, loses close to 20%.
Read that trend line again. The drop nearly doubled in eight months. This is not a level that settled and stayed. It is still moving, and it is moving in one direction.
Is Paid Search Quietly Picking Up the Slack?
Yes, and that is the trap. Australian search ad spend is forecast to grow 9.5% in 2026 to about A$7.25 billion, rising to 10.4% once generative and LLM search advertising gets folded in. The free click is shrinking while the paid version of the same click gets more expensive. A business that wants to stand in the same spot it used to occupy for free now has to pay for the privilege, every time.
Is This a Temporary Dip or a Structural Shift?
Gartner is forecasting traditional search engine volume to fall about 25% by the end of 2026 as more people ask a chatbot instead of typing into a search box. Combine that with a 37.8% AI Overview trigger rate already measured in Australian results, and the direction is not really in question. The size and speed of the drop is the only open variable, and it is trending toward faster, not slower.
Businesses that built a single acquisition channel and never priced what it was actually worth are the ones who will feel this first, because they have no baseline to measure the loss against. If you cannot say what an organic visit was worth to you last year, you cannot tell how much you have already lost this year.
Our own audit work across Australian businesses turns up the same channel-concentration pattern repeatedly: heavy reliance on one acquisition source, thin tracking on everything else (methodology and scoring detail: How We Score).
What I Would Actually Do With These Numbers
Do not treat this as a forecast to watch. Treat it as a number to act on this quarter.
Pull your own Search Console data and compare impressions against clicks on your highest-volume queries. If impressions are flat or rising while clicks are falling, that gap is the 37.8% happening inside your own account, not somewhere else in the market. Then price what an organic visit was actually worth to you historically, so the next drop has a dollar figure attached rather than a vague sense that things feel slower. Then decide, with that number in hand, how much you are willing to pay to replace the traffic that is not coming back for free.

Frequently asked questions
How common are AI Overviews in Australian search results?

How much click-through does a page lose once an AI Overview appears?
Ahrefs found the top-ranking page loses about 58% of its clicks once an Overview shows up on that query, based on December 2025 data, up from a 34.5% drop measured just eight months earlier.
Is Australian search ad spend rising or falling as organic clicks decline?
Rising. Australian search ad spend is forecast to grow 9.5% in 2026 to about A$7.25 billion, meaning the paid version of the same click most businesses used to get for free is getting more expensive at the same time the free version is disappearing.
