Troy Andres


“My interest in immigration law started in high school after I received an award for a creative writing piece that I submitted to the NSW Parliament in respect to meeting labour and skill shortages of the late 1980s and early 1990s.  At the time, Australia was experiencing the recession (it had to have) and we learnt about multi-skilling and tariff removal which gave rise to globalization (another word for competitive integration).  From that point onwards, I continually wondered why we (as a nation) did not just let people in to work on various temporary visas.

Clearly this was a naive view on immigration but it did spark a curiosity that continues to burn today.  That interest has turned into determination as a I guide and inspire my team to service our clients to the standards that we apply to our own lives.  That standard is about giving, caring, intelligence and awareness. It is about pushing ourselves beyond our own idea of excellence.”

Troy has been practising corporate immigration for over 20 years and loves helping clients navigate the complexity of global mobility and shaping the future of work.

Over two decades of practice, Troy has learnt that each business, and each person, is unique and what works in one particular situation may not necessarily work in another.  He has worked with mining giants, start-ups and some of the fastest growing tech companies in the world, and has helped each grow through driving change and best practice.  Although the strategies differ, the goal is always the same – seamless and fluid systems.

Troy understands that workforce mobility is changing in real time and in a world of constant disruption, the traditional approaches to immigration will not suffice.  Recognising this, he uses his commercial acumen in guiding companies with managing their risk profile and creating systems and protocols that enlighten both the business and the employee with respect to their rights and obligations under immigration law.

Helping a client is not just about giving advice.  It is about solving deeper issues in how to manage their business commercially and legally when it comes to immigration.

Global businesses need fluidity in managing their talent to grow.  However, fluidity only arises when there is alignment in all aspects of the employment process, from recruitment, to visa processing, onboarding, and compliance.

As a partner of the firm, Troy heads a team of equally driven and dedicated immigration lawyers.

“I have always been intrigued by the law and how it continues to impact our world and its ever-changing society, and vice versa.  My interest in immigration law started early in my career when I worked in the Pro Bono team at the Law Society of NSW.  I instantly knew that this was the area of law I wanted to practice in.

As I gained experience working in different global immigration law firms, I discovered that there was need to appreciate more than just immigration itself.  Focussing on businesses, I received hands-on experience dealing with the importance of compliance and commercial business decisions.  This was further refined when I became an in-house legal counsel at a Big-4 consultancy firm.  As a corporate and commercial legal counsel, I grasped the importance on how every decision, whether internal or external, affects the business.  That experience turned me into a business savvy corporate migration lawyer which has assisted my team and a number of businesses today.”
