AI News This Week: 5 Shifts Sydney Businesses Can’t Ignore

• Siri now runs on Google Gemini — assistant-based local search is going mainstream, so tidy your Google Business Profile and schema.
• Google’s May 2026 core update has finished rolling out; assess Search Console data before reacting.
• Google and Meta are trading manual ad control for AI automation — clean conversion tracking is now make-or-break.
• Australia keeps a light-touch AI stance, but Privacy Act disclosure rules for automated decisions start 10 December 2026.

Apple just handed Siri’s brain to Google — and that single deal will quietly change how millions of Australians search for local businesses from their iPhones. Here’s what happened in AI this week, and what it actually means for your marketing.

Siri now runs on Google Gemini — and your customers will use it

At WWDC on Monday, Apple announced a completely rebuilt Siri powered by Google’s Gemini models, under a deal reportedly worth around US$1 billion a year. The new Siri handles conversational, multi-step requests — think “find me a tyre shop near Parramatta that’s open Saturday and book a fitting” — rather than just reading out a list of links. Apple also unveiled an Extensions system in iOS 27 that lets users pick ChatGPT, Gemini or Claude as their default assistant.

For your business, this is the clearest signal yet that voice and assistant-based search is going mainstream. Given roughly half of Australian smartphones are iPhones, a meaningful slice of your local customers will soon be asking an AI assistant for recommendations instead of scrolling search results. Assistants pull heavily from structured data: your Google Business Profile, accurate opening hours, reviews and schema markup on your site. If those are messy or stale, you simply won’t be the answer Siri gives.

Google’s May core update has finished rolling out

Google’s May 2026 core update — the second core update of the year — has now completed its rollout, and it was a volatile one. The update continued Google’s pattern of folding helpful-content signals into core ranking, rewarding fast-loading sites with genuinely useful pages and demoting thin, mass-produced content.

If your traffic moved sharply in the last fortnight, now is the time to assess — not panic. Rankings often keep settling for a week or two after a rollout finishes. Check Search Console for which pages and queries actually shifted, and compare winners against losers. The consistent theme across 2026’s updates is that first-hand expertise and good page experience win, while generic AI-spun content loses. If you took a hit and can’t see why, a proper SEO audit beats guessing.

Google Marketing Live: AI agents are coming to your ad account

At Google Marketing Live, Google announced a unified Gemini-powered agent that works across Google Ads, Analytics and Merchant Center as an “always-on strategic partner”, plus an upgraded Asset Studio that turns brand guidelines into ad creative automatically. AI Max campaigns also get preferential reach into AI Mode and AI Overviews — the new AI-generated layer of Google Search where ads increasingly appear.

The practical takeaway: Google is steadily trading manual control for AI automation, and advertisers who feed the machine good inputs win. That means watertight conversion tracking, first-party customer data and clear brand assets. Small businesses running ads on autopilot without proper conversion data will burn budget faster than ever, because the AI optimises towards whatever signal it’s given — even a bad one. Before switching on any of these AI features, make sure your tracking actually measures leads and sales, not just clicks.

Meta restructures around AI as its ad business overtakes Google

Meta began laying off around 8,000 staff this week while moving another 7,000 into AI-focused teams — a full-tilt bet on AI across Facebook, Instagram and Threads. It comes as eMarketer forecasts Meta’s global ad revenue will edge past Google’s in 2026 (roughly US$243 billion versus US$240 billion), with Threads ads now available globally.

Expect more AI-generated ad formats, more automated Advantage+ style campaigns and less granular targeting control on Meta platforms. For local businesses, Threads is worth a small test budget while it’s cheap — early-platform inventory has historically been a bargain. But the same rule applies as with Google: automation rewards advertisers with strong creative and clean pixel and conversion data, and punishes everyone else.

Australia confirms its light-touch AI rules — but privacy deadlines loom

Australia is sticking with its light-touch approach to AI regulation: no standalone AI Act, with the new AI Safety Institute coordinating voluntary guidance instead of mandatory guardrails. That’s good news if you’re experimenting with AI tools — no compliance cliff is coming for everyday business use.

One date does matter, though: from 10 December 2026, Privacy Act reforms require businesses covered by the Australian Privacy Principles to disclose in their privacy policy when personal information feeds substantially automated decisions. If you’re using AI for lead scoring, dynamic pricing or automated customer responses, pencil in a privacy policy review before summer. It’s a small job now and an awkward scramble later.

What to do this week

• Tidy your structured data. Update your Google Business Profile, opening hours and schema markup so AI assistants like the new Siri can confidently recommend you.
• Review your post-update rankings. Pull Search Console data from the past month, identify pages that moved during the May core update, and prioritise improving — not deleting — content that slipped.
• Audit your conversion tracking before trusting AI campaigns. Every AI ad feature Google and Meta announced this week optimises towards your conversion data. Verify it’s tracking real enquiries and sales before handing over more control — or get Google Ads management help to set it up properly.
