  I would like to share some very positive feedback on our auditors, Wellden Turnbull, and, in particular, our lead auditor, Bobbi-Jo. The firm has consistently demonstrated the highest levels of professionalism, diligence, and expertise throughout our audits and in providing strategic advice.
Bobbi-Jo has been truly exceptional, going above and beyond to ensure our requirements are met, often working tirelessly — including long hours — to deliver accurate, timely, and thorough results. Her attention to detail, responsiveness, and commitment to supporting our business make a real difference, particularly in navigating complex matters.
I would also like to highlight the excellent work and support of Robin John and Emma Green, who have been consistently thorough, reliable, and professional, providing valuable insights and guidance in both audit and tax-related areas. Together, the Wellden Turnbull team has provided not only technical excellence but also trusted partnership and strategic support.
We are extremely grateful for their dedication and for the outstanding work that Bobbi-Jo, Robin, Emma, and the wider team continue to deliver.
