ChatGPT costs money but is mature, broad and far safer for Australian business data. Here's which to pick, and when. - Author: Adam - Tags: AI Assistants & Chatbots, DeepSeek, ChatGPT, #comparison Head-to-head verdict [**16**/25DeepSeek](https://www.theaidirectory.com.au/review-deepseek-australia-2026/)[**21**/25ChatGPTWinner](https://www.theaidirectory.com.au/chatgpt-review-australia/) **Our pick: ChatGPT.** The verdict below says who should buy the other. > **Winner: ChatGPT** for almost every Australian business that touches client data, financial records or anything commercially sensitive. It scores 21/25 against DeepSeek's 16/25, and the gap is not really about capability — it's about where your data sleeps. DeepSeek stores everything on servers in China under Chinese law, and the Australian federal government has banned it on all government devices. **Pick DeepSeek only** if you're an individual doing low-stakes work who will never type anything sensitive, or you have a technical team that can self-host its open-weight models on Australian infrastructure. For the typical small business, ChatGPT Plus at A$30 a month is the safer, broader and more accountable choice. > > *Last reviewed: 25 June 2026 by Adam.* These are the two ends of the AI-assistant market in 2026\. DeepSeek is the free upstart from a Chinese lab that shocked the industry by matching frontier models at a fraction of the cost. ChatGPT is the mature, US-built default that most Australians already know. On raw capability they're closer than the price gap suggests. On everything an Australian business should actually weigh — data location, government clearance, billing, support — they're worlds apart. This is less a feature shootout than a question of how much risk a free tool is worth. ## At a glance | | DeepSeek | ChatGPT | | ---------------------- | ---------------------------------------------------------- | ------------------------------------------------------------------- | | **Our score** | 16/25 ⭐⭐⭐⭐ (AU Fit 1/5) | 21/25 ⭐⭐⭐⭐ (AU Fit 3/5) | | **Maker / origin** | DeepSeek (High-Flyer), Hangzhou, China | OpenAI, United States | | **Entry price** | Free (web + app chat) | Free tier, then Plus A$30/mo (native AUD) | | **Data residency** | China only — no AU, APAC or US option | US on consumer plans; AU residency on Enterprise/Edu/Healthcare/API | | **AU government** | Banned on all government devices (PSPF Direction 001-2025) | Permitted; no IRAP statement for PROTECTED work | | **AUD billing** | No (USD); GST undisclosed | No (USD); GST added at checkout | | **Context window** | \~1 million tokens | Large, model-dependent | | **Breadth** | Chat, reasoning, vision, web, API, open weights | Writing, code, images, voice, Custom GPTs, Deep Research | | **Top Pick eligible?** | No (AU Fit 1/5 — Australian Fit gate) | No (AU Fit 3/5 — Australian Fit gate) | ## What both tools actually do Both are general-purpose AI assistants: type a question, paste a document, upload an image, get a considered answer. Both handle reasoning, summarising, drafting, analysis and code. Both have web search built in, mobile apps, and an API for developers. For everyday work — drafting an email, summarising a report, brainstorming a plan — a non-technical Australian would struggle to tell their raw outputs apart. The split is in how far each reaches, and in what surrounds the chat box. **DeepSeek** is the capability bargain. Its V4-series models carry a roughly one-million-token context window — enough to hold a full year of board minutes or an entire contract in one go — and its DeepThink reasoning mode works through problems step by step, showing its logic. It does image analysis, web retrieval, and an OpenAI-compatible API priced at a fraction of the competition. Most importantly for technical teams, the underlying models are released as open weights under the MIT Licence, so they can be run on your own infrastructure entirely. The hosted free chat at chat.deepseek.com is what most small-business owners would actually use — and it's that hosted product that carries the warnings. **ChatGPT** is the breadth leader. Under one OpenAI subscription you get writing, coding, image generation, conversational voice, web browsing, Custom GPTs, Deep Research and code execution. No competitor matches that range on a single bill. The free tier is genuinely useful, Plus covers most professional work, and OpenAI ships new features faster than anyone — the 2026 cycle alone added a cheaper Go tier, image-generation upgrades, and Australian data residency on business plans. The catch is that it isn't free for serious use, and the consumer plans now carry ads. In short: DeepSeek gives you frontier reasoning for nothing, with a serious string attached; ChatGPT gives you the broadest, most polished toolkit for a fair monthly fee, with proper accountability behind it. ## Pricing in Australia Neither tool bills in Australian dollars. Both quote USD, and your card lands at your bank's exchange rate on the day. We convert at roughly 1.40 and show the AUD figures ex-GST; treat them as estimates. **DeepSeek** is free for web and mobile chat — no Plus or Pro tier exists, and there's nothing to upgrade to on the consumer side. Its API is where money changes hands, and even there it's cheap: V4-Flash runs about US$0.14 per million input tokens (\~A$0.20) and US$0.28 per million output (\~A$0.39), with V4-Pro a few times higher. New API accounts get five million free tokens to trial. DeepSeek's pages make no mention of GST for international customers, so whether it's added is something we can't confirm — the AUD figures are a straight currency conversion, not a GST-inclusive quote. Australian businesses receiving a USD invoice should seek advice on their own GST position. **ChatGPT** runs a free tier (now with ads in Australia since 26 March 2026), a Go tier at A$13/month (native AUD pricing, also ad-supported), and Plus at A$30/month — the right call for most professionals, with full reasoning and no ads. Above that sit two Pro tiers (from A$155/month, native AUD pricing), ChatGPT Business from A$28 per seat, and Enterprise with a custom quote. GST is added at checkout for Australian accounts, which is cleaner than DeepSeek's silence on the question. The honest read: on price alone, DeepSeek wins outright — free beats A$34/month every time. But price is the wrong axis to judge this pairing on. The real cost of DeepSeek isn't on the invoice; it's in where your prompts end up. ChatGPT's monthly fee buys you US hosting, GST-clean invoicing, and — on the right plan — Australian data residency. That's what the A$34 is really for. ## Where DeepSeek wins - **It's free, and genuinely capable.** No subscription for consumer chat, and the reasoning quality with DeepThink engaged is among the strongest publicly available. For a sole trader doing occasional drafting or brainstorming, zero cost with real ability is a strong pull. - **A massive context window.** Roughly one million tokens means you can paste an entire report, contract or data export and ask questions across the whole thing without the model losing the thread. - **Cheap, OpenAI-compatible API.** For developers, the API costs a fraction of the competition and mirrors OpenAI's interface, so migration friction is low. - **Open weights are the escape hatch.** The MIT-licensed models can be self-hosted on your own Australian or compliant cloud — which removes the China-hosting problem entirely and gives you world-class performance. For organisations with the technical capability, this is the most compelling use case by far, and a materially different product from the hosted app. ## Where ChatGPT wins - **Your data isn't in China.** Consumer plans are US-hosted, and Enterprise, Edu, Healthcare and API customers can keep data resident in Australia. Either way, it's not subject to laws that compel government access — the single biggest reason to choose it for business. - **It's allowed where DeepSeek isn't.** DeepSeek is banned on Australian government devices under PSPF Direction 001-2025; ChatGPT carries no such ban. For anyone in a government supply chain, that settles it. - **The broadest toolkit on one bill.** Writing, code, image generation, voice, Custom GPTs and Deep Research under a single subscription — DeepSeek is a strong chat-and-reasoning tool, but it doesn't span this range. - **GST-clean, accountable billing.** GST is added at checkout for Australian accounts, and there's a US company standing behind the product. DeepSeek's GST treatment is undisclosed and its only support is email, run out of China. - **Maturity and track record.** ChatGPT is the reference point most people already know, with a longer, steadier operating history. DeepSeek suffered a roughly 13-hour outage in March 2026 — the longest in its history — a real mark against it for any workflow that depends on uptime. ## Which to pick — decision framework - **You handle client data, financial records or anything commercially sensitive** → **ChatGPT**. The data-sovereignty exposure makes DeepSeek's hosted product the wrong tool, free or not. - **You're an Australian government employee or contractor** → **ChatGPT** (or Microsoft Copilot for PROTECTED work). DeepSeek is banned on government devices; ChatGPT lacks IRAP but isn't prohibited. - **You want the broadest single subscription** → **ChatGPT**. Voice, images, Custom GPTs and Deep Research on one bill have no DeepSeek equivalent. - **You're an individual doing low-stakes work and will never type anything sensitive** → **DeepSeek**. The free reasoning and context window are genuinely good — go in eyes open about where your data goes. - **You have a technical team that can self-host** → **DeepSeek's open-weight models**, deployed on your own Australian or compliant cloud. World-class performance, residency problem solved. - **You want native AUD pricing and Australian data centres on a consumer plan** → neither leads here; look at Gemini, which our category roundup covers. ## The verdict **Winner: ChatGPT, for the overwhelming majority of Australian businesses.** It scores 21/25 to DeepSeek's 16/25, and the five-point gap is almost entirely about trust, not talent. DeepSeek is brilliant technical work — the most capable free assistant you can use, with frontier reasoning and a giant context window for exactly zero dollars. But its hosted product stores your prompts, files and chat history on servers in China under laws that can compel government access, and the Australian federal government has banned it on every government device for precisely that reason. No amount of capability offsets that for a business handling sensitive material. **ChatGPT earns the win by being the safe, broad, accountable default.** Plus at A$30 a month buys US hosting, GST-clean invoicing, the widest toolkit on a single subscription, and — on Enterprise — genuine Australian data residency. It isn't perfect: consumer plans are USD-priced, ads now sit on the free tiers, and there's no IRAP statement for government-classified work. But none of those are disqualifying the way DeepSeek's data picture is. The honest framing: **DeepSeek is the better free tool and the worse business decision.** Use it for low-stakes personal tasks, or self-host its open weights if you have the team to do it. For everything else — anything with a client name, a dollar figure or a commercial secret in the prompt — pay for ChatGPT. Both tools miss our Australian Fit gate, so neither is a category Top Pick; but between them, ChatGPT is the one most Australians should actually be using. *This comparison is general information, not compliance or professional advice. Data-sovereignty and security obligations vary by industry and contract — if you handle regulated, government or commercially sensitive material, confirm your own data-handling requirements before committing to either tool.* Update history - **25 Sep 2026** — **ChatGPT Plus is A$30 a month, not "about A$28".** Four places (the quick-pick entry price, the verdict, the FAQ and its JSON-LD twin) still carried a June-era conversion of US$20, while the pricing paragraph in this same file and the ChatGPT review both say OpenAI has shown Australians a native **A$30** since before 2 September. Our AUD pricing rule: a native AUD price is the price. Caught by the cross-file price sentry (`check-price-consistency.py`), which now agrees with the review. No score change.

ChatGPT, for almost any business handling sensitive data. It scores 21/25 against DeepSeek's 16/25, mainly because DeepSeek stores all data in China under laws that can compel government access, and is banned on Australian government devices. DeepSeek wins only for low-stakes personal use or technical teams self-hosting its open-weight models. ### Is DeepSeek really banned in Australia? It's banned on Australian government devices, not for private use. On 4 February 2025 the Department of Home Affairs issued PSPF Direction 001-2025 prohibiting DeepSeek across all government devices, citing security risk and exposure to foreign-government directions. Victoria and South Australia followed. Private individuals and businesses can still use it. ### Which is cheaper, DeepSeek or ChatGPT? DeepSeek, by a wide margin — its web and app chat is free, with no subscription tier. ChatGPT's free tier carries ads in Australia, and serious use means Plus at A$30 a month. But the real cost of DeepSeek isn't the price; it's where your data is stored. ### Where does each tool store my data? DeepSeek stores everything in the People's Republic of China, with no AU, APAC or US option. ChatGPT hosts consumer-plan data in the US, and offers Australian data residency on Enterprise, Edu, Healthcare and API plans. Neither hosts consumer data in Australia natively. ### Can I use DeepSeek safely if I avoid the China hosting? Yes, if you have a technical team. DeepSeek's models are open-weight under the MIT Licence, so you can self-host them on your own Australian or compliant cloud — a world-class product that sidesteps the residency problem entirely. That's a materially different setup from the free hosted chat most people use. ## Read next - Full reviews: [DeepSeek](https://www.theaidirectory.com.au/review-deepseek-australia-2026/) (16/25, AU Fit 1/5) and [ChatGPT](https://www.theaidirectory.com.au/chatgpt-review-australia/) (21/25, AU Fit 3/5) - Another China-hosted option, reviewed honestly: [Qwen Chat](https://www.theaidirectory.com.au/review-qwen-chat-australia-2026/) - How we score: [Methodology](https://www.theaidirectory.com.au/methodology/) ## Sources This comparison draws on The AI Directory Australia's underlying reviews of [DeepSeek](https://www.theaidirectory.com.au/review-deepseek-australia-2026/) (16/25, AU Fit 1/5) and [ChatGPT](https://www.theaidirectory.com.au/chatgpt-review-australia/) (21/25, AU Fit 3/5), each scored against our five-criteria framework and verified against the vendors' own pricing, product and policy pages.
