The latest chapter in our firm’s story is BYRONS.

Our rebrand is the opportunity to maintain independence, keep a strong connection to local clients and continue to grow in capability to support clients globally.

The firm was founded in 1955 with the name Byrons Chartered Accountants and specialised in audit, taxation and business advisory services. We started as a sole practitioner and continued to grow to become a leading Sydney advisory firm.

Our firm history is:

  • We were founded by John Byron in 1955 and had the firm name Byrons Chartered Accountants.
  • The firm joined the Moore network in 2016 as Moore Stephens (NSW).
  • We rebranded in 2020 to Moore Australia (NSW).
  • Today we are BYRONS, with a different look, rebrand and greater network connections as part of PrimeGlobal.
