About Katherine O’Connor

Katherine was announced as Director at Allan Hall in May 2023, following her unwavering commitment to her clients and her contribution to the growth and development of our team at Allan Hall.

Katherine was “born and bred” on the Northern Beaches and, after studying at Newcastle University and spending four years gaining experience in the Sydney CBD, she was delighted to return home to join Allan Hall.

Since qualifying as a Chartered Accountant in 2007, Katherine has specialised in providing practical and empathetic advice to small and medium sized businesses, particularly in the areas of tax management, cash flow and profit enhancement.

She takes pride in working with clients to identify the right path through the regulatory and commercial challenges which face all businesses today.

With her role as CFO of her husband’s expanding Fire Protection company, Katherine has real personal insight into the difficulties facing her clients from debtor management and cash flow to employment issues and plenty in between.
