The Tax Institute’s National GST Conference for 2025 – Australia’s pre-eminent event for GST practitioners and advisory specialists. This year the conference was held at the Hilton Hotel Sydney from 16–17 October 2025. We’re excited about our program for the year, featuring a mix of technical and case law updates, practical panel sessions and deep dives into technical issues.
This year, we were honoured to welcome Lachlan Wolfers, CTA, KPMG International as our keynote speaker to reflect on 25 years of GST in Australia, and what the future might hold. There was also be a particular focus on hot button issues – the first reports from taxpayers and advisors on how Supplementary Annual GST Returns are working in practice, and the impact of Division 93 of the GST Act on refund claims. The economic update also touched on the upheaval to global trade arising from renewed global tariffs.
