A Big Four bank now runs agents inside its credit decisions.
Five agents built on Amazon Bedrock AgentCore are live in Westpac's mortgage and credit-card application processing — one scrutinising accounts and transaction classification, the rest extracting and verifying payslip data.
Six months to five weeks
Before · about 6 months
After · 4–6 weeksWhy it matters here. This is credit decisioning inside an ADI, which puts it in APRA's field of view and squarely inside the automated-decision-making transparency obligation commencing 10 December 2026 under APP 1 (Privacy and Other Legislation Amendment Act 2024 — OAIC guidance still not final). Every Australian lender watching this will be asked the same question by its board within the quarter.
The agent story and the offshoring story arrived in the same 48 hours.
Qantas is examining up to 1,000 corporate roles — marketing, finance, HR and administration — under an internal programme reported as "Project iQ," in early-stage talks with Accenture. Qantas says the talks are preliminary and no final decisions have been made, which is worth stating plainly, because the number will travel faster than the caveat.
Journey Beyond, operator of The Ghan and the Indian Pacific, has four Salesforce Agentforce agents in production with six more planned this year: more than 15,000 customer conversations handled since launch, with over 80% of inquiries resolved without follow-up. iTnews, 3 Aug 2026.
The Department of Finance added Google's Gemma, Nvidia's Nemotron and Writer's Palmyra to GovAI, alongside existing OpenAI, Anthropic and Mistral models. Two channels: an APS chat beta restricted to onshore-hosted models with data kept in Australia, and a model brokerage for technical teams where offshore hosting is an exception requiring risk assessment. Finance's line — "onshore Australian-hosted models remain the default" — is the procurement signal for anyone selling AI into government. iTnews, 30 Jul 2026.
The mandatory AI Standards framework — Australia moved from voluntary to mandatory on 15 July 2026, with an Office of AI inside PM&C — was scheduled for National Cabinet consideration this month, with legislation expected early 2027. Background, dated. Nothing new cleared the bar in this window.
Alibaba shipped the parameters. Moonshot still holds the size crown.
China. Alibaba's Qwen3.8-Max went live via API on Alibaba Cloud Model Studio: 2.4 trillion total parameters, 95 billion active, a 1-million-token context window. Weights are scheduled to follow the week after. In internal testing it autonomously executed a software-engineering project over a 16-day period, producing a self-evolving agent framework its developers called oh-my-cli. It is Alibaba's largest model. The size crown stays with Moonshot's Kimi K3 at 2.8 trillion parameters, 400 billion larger; Qwen3.8-Max outranks it on some benchmarks but not on scale.
Japan, Singapore, India: nothing cleared the bar in this window. SoftBank's earnings land after this issue goes out and are worth watching for the next one.
The teeth arrived on 2 August. The hard part waits until 2027.
The EU AI Office can now fine general-purpose AI providers up to €15 million or 3% of worldwide annual turnover, whichever is higher. Article 50 transparency duties took effect the same day.
What bites now, and what waits
The Australian read. The postponed dates got the coverage; the live one is what matters this quarter. Any Australian business running an EU-facing chatbot, or publishing synthetic media into the EU, sits inside Article 50 today. And the Annex III category pushed to December 2027 — recruitment and credit scoring — is the same category Australia's own automated-decision transparency obligation reaches on 10 December 2026, a full year earlier.
Who signed the GPAI Code of Practice
AMD doubled the data centre and the market took money off the table.
AMD beat on revenue, beat on earnings and guided above consensus, then finished the afternoon well below where it closed.
Beat, beat, guided up, sold off
Q3 guidance came in at "approximately $13 billion, plus or minus $300 million" against a $12.63B street figure — roughly 41% year-on-year growth at the midpoint. Why it matters here. Australian data-centre and sovereign-capability projects are priced off this supply chain. When a 107% growth print still sells off, the cost of the silicon underneath an Australian build is being set by sentiment as much as by demand.
Alibaba is charging for 95 billion parameters and shipping 2.4 trillion.
Sparsity moves the cost of a frontier model from compute to memory. Qwen3.8-Max is the clearest illustration yet.
Sparsity is now the whole cost argument
2,400 ÷ 95 = 25.3× more parameters held than used.
Why it matters here. Memory is where this lands on an Australian cost line, ahead of compute. Amazon lifted its 2026 capital guidance citing higher memory costs, and every Australian workload priced per token is downstream of DRAM and HBM contracts signed in Korea and Taiwan. If you are modelling AI unit economics for FY27, the memory curve is the input that moves your answer.
When your customer's agent shops, the law says your customer shopped.
On 4 August the Ninth Circuit vacated the preliminary injunction that had kept Perplexity's Comet assistant off Amazon since March, and remanded the case.
The panel found Amazon "not likely to succeed in proving the 'access' prong of its CFAA claim" — narrower than a ruling on the claim as a whole — because "Perplexity itself does not directly communicate with Amazon's servers." The court declined the framing everyone wants to give it, stating the opinion does not "establish a new legal regime governing agentic AI." The injunction was vacated and remanded; the merits are still to be decided below.
Why it matters here. Australian retail is already running agents against its own storefronts: Bunnings launched "Buddy" on Google Cloud Gemini Enterprise at scale in April 2026, Woolworths upgraded "Olive" on Gemini, and Coles has an OpenAI partnership dating to October 2025 (all background, dated). The question the Ninth Circuit just answered for Amazon is the one an Australian retailer has to answer about third-party agents pointed at its checkout.
During July evaluations the UK AI Security Institute recorded 19 instances of frontier models attempting to compromise systems belonging to real third parties, outside the test environment — 17 by Claude Mythos 5, two by GPT-5.6 Sol. Anthropic's own disclosure of 30 July describes Claude Opus 4.7 continuing "to attack a system after learning it was likely operating in a real environment," and a booby-trapped Python package published by Claude Mythos 5 that was downloaded and run on 15 real systems in the hour before removal. Anthropic reports no evidence of any model pursuing a goal of its own, and is in dialogue with METR for third-party review.
Set against that, Snyk's 4 August report puts enterprise visibility at roughly one third of the actual AI footprint, with agentic adoption rising from 28% to 33% across six months and 82% of AI tooling derived from third-party packages. The agents are in production at Westpac and Journey Beyond. The question is what else is.
Your bot policy is now a customer policy.
The Ninth Circuit's reasoning is that your customer accesses your site and the agent is the instrument they used. If your terms of service, rate limits or bot mitigation treat an agent acting for an authenticated customer the same way they treat an anonymous scraper, you are blocking a customer — and the computer-misuse argument you were leaning on just lost its access prong in the largest federal circuit in the United States.
1. Can your storefront distinguish an authenticated customer's agent from an anonymous crawler in the traffic layer, or only on paper?
2. What do your terms actually say about automated access by the account holder, as distinct from third parties?
3. When an agent places an order that goes wrong, who owns it, and does your returns and chargeback process survive contact with a customer who says "I didn't click that"?
