Global legal technology provider Thomson Reuters has launched two agentic artificial intelligence solutions for Australian legal, tax, and compliance professionals, representing what the provider has claimed to be the most advanced AI initiative in the country to date.
Thomson Reuters has launched two new agentic AI products for Australian legal and corporate professionals, bringing “fiduciary-grade AI” directly into the daily workflows of legal, tax, and compliance teams.
The global legal tech provider emphasised that the launch represents its “most advanced AI offering” in Australia to date.
The launch comes as the company’s AI technology, CoCounsel, surpasses 1 million users across 107 countries and territories, supporting high-stakes legal, tax, and compliance work worldwide.
Unveiled at last week’s third annual SYNERGY Sydney conference, the global legal technology provider is rolling out Westlaw Advantage Australia and ONESOURCE+, both powered by its AI platform, CoCounsel.
Thomson Reuters explained that the rollout of these two tools reflects a broader shift in regulated industries, with AI moving “from pilots to production systems” that are fully embedded into daily professional workflows.
Westlaw Advantage Australia is powered by its Deep Research capability, enabling legal professionals to hand over entire research questions to an AI agent that autonomously designs research strategies, outlines its reasoning, sources relevant information, and builds the foundation for legal arguments.
Following successful launches in the United States, United Kingdom, and Canada, Thomson Reuters plans to expand Deep Research to Singapore, Hong Kong, and New Zealand within the next 12 months.
Already live across the Asia-Pacific (APAC) and Middle East and North Africa (MENA) regions, ONESOURCE+ is Thomson Reuters’ intelligent compliance networking, which connects tax, trade, legal and risk solutions into a coordinated network.
Rather than functioning as a single platform, it integrates data, content, and workflows to give organisations a governed view of their global compliance and risk exposures.
In Australia, key offerings include ONESOURCE Global Indirect Compliance, which uses agentic AI to fully automate multi-jurisdictional tax filings from start to finish, and Sales and Use Tax AI, which the company said can slash preparation time by 40 to 60 per cent for US entities navigating thousands of jurisdictions.
Vishal Bali, the managing director for Asia and emerging markets at Thomson Reuters, explained that in regulated professions, AI must be accountable, not just impressive, noting that the introduction of the new tools embeds fiduciary-grade agentic AI directly into professionals’ daily workflows.
“In regulated professions, AI can’t just be impressive – it has to be accountable. Legal, tax and compliance professionals in Australia are moving beyond experimentation and demanding AI they can rely on for high-stakes work,” Bali said.
“By bringing Westlaw Advantage Australia and ONESOURCE+ to market, we’re embedding fiduciary‑grade agentic AI directly into the workflows professionals use every day – grounded in authoritative content, deep domain expertise, and governed by design.”
