Principal Lawyer - Corporate & Commercial
Leisa Bayston

With a lifetime of experience across some of the most technical aspects of commercial law and financial management, Leisa is uniquely placed to advise in the start-up space. With her integrated approach and exceptional instinct for risk, she gives innovators the tools to bring big ideas to life.

After kick starting her career in corporate tax with “big four” consulting firms, Leisa moved into funds management. She was then a senior lawyer in the commercial division of a major law firm before spending 5 years in-house at Macquarie Bank. Never content with received knowledge or the well-trodden path, she then went on to set up a successful boutique commercial practice in Melbourne with her life and business partner, Alister.

Running her own practice was the culmination of decades of learned experience in the commercial space, which ignited Leisa’s passion for working with start-ups. Drawing on the lessons of the past, she started working with founders in the technology sector, building them the legal foundations for success before guiding them through the full start-up lifecycle, from growth and scaling to eventual exit.

Approaching every professional engagement as a partnership, Leisa lives and breathes the methodology. She digs deep to understand your ideas and motivations – as well as your appetite for risk and opportunity. Fully invested in the success of your businesses, Leisa aims to eliminate future roadblocks and equip you with the legal armour to take your initiative onwards and upwards.


Leisa has many proud achievements, and they all have one thing in common. They are circumstances where a client has found themselves in a difficult and often complex situation and she has been able to use her problem-solving skills, legal knowledge, and tenacity to get the desired result.
