What customers say

Based on genuine customer reviews

Tax returns, payroll and general accounting work form the backbone of what clients bring to this practice, and the feedback consistently reflects careful handling of both personal and company matters. Many reviewers note that legitimate deductions were identified which had previously been missed, producing stronger outcomes at tax time. One thing mentioned again and again is the accessibility of the team, with clients describing being given proper time in conversations, complex matters explained clearly, and practical advice that could be applied to their operations straight away.

Named staff, particularly Jenny and Erika, are frequently praised for their professionalism, patience and genuine interest in the success of the businesses they serve, including a physiotherapy practice. Questions, whether basic or involved, are answered with sincerity and without any sense of being rushed. Deadlines are another recurring theme, with returns completed ahead of schedule and work delivered across consecutive years without disruption. The attention to detail extends beyond the numbers, with clients describing a personalised approach that treats their enterprise as if it were the firm's own, and it is this combination of business management guidance and tax preparation that brings them back annually.

I have had an excellent experience working with Jenny and Nucleus Accounting. Jenny provided professional and strategic guidance in establishing The A&W Richer Pty Ltd and The Richer Family Trust for my investment property structure. Her knowledge of company and trust structures, compliance requirements, and long-term planning was evident throughout the process. All documentation was handled efficiently, accurately, and with a high level of attention to detail. Jenny communicated clearly, acted promptly, and ensured the structures were set up correctly from both a legal and tax perspective. I value the quality of advice and professionalism provided and intend to continue working with Jenny and Nucleus Accounting on an ongoing basis. I would confidently recommend her services to investors seeking a reliable and well-informed accounting partner.

Jenny and the Nucleus team have been doing my business / personal accounting and taxes for the last 3 years. I can't thank them enough for the level of service and attention they have provided. I've had accountants before who have completely missed what Jenny and team have picked up - saving me so much time, eneregy and stress. Highly recommended.

I could not be happier with the service provided by Jenny and the entire team at Nucleus Accounting. After using them for my individual tax returns for the past five consecutive years, I have complete confidence in their expertise and professionalism. Jenny is truly exceptional—she is not just an accountant who processes forms, but a dedicated advisor. She consistently goes above and beyond to ensure my tax return is handled with meticulous detail, proactively identifying every legitimate deduction to maximize my refund. If you are looking for an accountant who is highly professional, always available, and treats your financial well-being as their top priority, look no further than Nucleus Accounting. They have certainly earned my five-star loyalty!
