I have used the services of Antonas & Co for several years now and they are quite simply a wonderful company to deal with. Daniel is so helpful with all my random questions I have concerning my business. Nothing seems to be a problem as he is always patient with me. My BAS and tax needs are always handled quickly and it gives me the confidence of knowing that I’m in safe hands. I recommend this local family wholeheartedly to take care of your requirements.

In our lengthy dealings with Accountant Daniel Antonas and experienced staff members, we have found this team of people to be extremely approachable. They have professionally guided us through the transition of our family operated farm business to future succession planning. Their knowledgeable assistance regarding advice for all our business matters has been invaluable, resulting in positive financial outcomes. We would highly recommend them to anyone seeking any aspect of professional accountancy guidance.
