As Principal of the firm with over sixteen years of experience, Melissa sets the tone for the culture we carry here at The Firm On The Avenue. As a mum to four daughters, Melissa goes out of her way to ensure that her team members enjoy a balanced home & work life. With all of Melissa’s experience and qualifications it is her drive for the clients that sets her apart. Some of Melissa’s specialty areas include traffic, wills & estates, family, crime, conveyancing and international. When Melissa isn’t running over to court or grabbing her 5th coffee for the day, you might find her burning off some steam at our local F45. If you can’t spot her there she may be plotting out her next big move; State Coroner. Fittingly for Melissa she has also chosen a fall-back option that we all really support; Aldi’s International Wine Buyer.



Wills and Estates

Sunserae has brought with her many years of experience working in the legal industry. She works as a paralegal here at the Firm and heads up our Family Law Paralegal Team.

Sunserae has swapped the red dirt of the Pilbara for the beautiful blue ocean of Hervey Bay.  Out of the office she’s is enjoying the beauties of Hervey Bay with her daughter, usually by the water.

Her dream is to travel to experience all the fine wine & cuisine that Italy has to offer. She has a passion for netball so you might find her down at the local courts watching the rising stars of Hervey Bay on a Saturday morning.


Conveyancing, Criminal and General Paralegal

Jess joined the firm and the industry in October 2021 with a Bachelor of Business and a keen interest in law. With a passion for helping others, she enjoys helping clients whether it be with buying or selling their house. If she’s on top of the workload she can often be found helping or badgering other staff members to show her more about law.

Outside of work, Jess is heavily involved in Hervey Bay Netball and loves coaching her junior team. If she’s not at the courts, she is either reading a book, in her rose garden or out at the beach with her puppy.


Family Law Clerk

Alanna joined the firm at the start of 2022 and has shown her passion for Family Law and her willingness to learn every day.

She is currently finishing her Bachelor of Laws and aims to be admitted as a lawyer in 2023.

Alanna believes that when people are going through one of the most difficult times in their life, they need extra support and understanding accompanied with valuable and straightforward advice. They want someone who can empathise with them and fight for their interests.

Even though the law is complicated, the advice of a lawyer doesn’t have to be.


Bianca is our recently admitted lawyer who is currently working in the area of Wills, EPOA’s, Estates and Trusts. She enjoys helping our clients have some peace of mind that their affairs will be in order when they pass away.

In her spare time, Bianca loves spending time with her family and friends of both the two and four-legged variety, being owner of three dogs named Cleo, Willow and Bella, and a number of riding horses. She also loves the great outdoors, travelling and exploring.

Alternate career choice: Archaeologist/Ancient Historian.



Conveyancer – Residential and Commercial

Kelsey is our resident office-jester, if she isn’t laughing she is sure to be making someone else laugh nearby. With her law degree almost complete, Kelsey’s fresh take on legal matter and keen interest in crime & conveyancing make her invaluable to our female-led team. Kelsey is the paralegal to the principal of the firm – Melissa – and has over a decade in administrative experience. Out of the office, Kelsey is a family ‘gal’ and will do any activity if it means being able to spend time with her nieces. When Kelsey isn’t burning all her energy on our client’s needs, she is plugging in her headphones, blasting the tunes and going on a long run around the Bay. We’d go with her but we know we’d never keep up!


Conveyancer – Residential and Commercial

As a fresh face to Hervey Bay, Arlia has spent several years studying Law and Science in Brisbane before relocating to pursue a career in Conveyancing. Arlia has a passion for helping all clients, and her unwavering patience ensures that her clients feel calm, secure and looked after every step of the way.

In Arlia’s spare time she enjoys nothing more than spending time with her friends and family, and baking.



Sally is a highly skilled Office Administrator with an impressive background specialising in administrative work and office support. Known for her strong communication skills she connects well with clients and work colleagues while delivering a commitment to excellence, honesty and integrity.

Sally has enjoyed a long career and plenty of success in Equestrian Events and Tennis which saw her win Hervey Bay Sportsperson of the Year in 1995. In her spare time she loves travelling the globe sightseeing and catching up with family and friends.

Her Birthstone: Coffee Bean



Currently applying some of her many skills in the accounts department.

Her weekends are enjoyed spending time with the hubby and two fur babies planning the next great escape in the motor home.



With her degree in banking and finance, Karen is an eagle-eye when it comes to figures. As our paralegal here at the firm, Karen is especially fulfilled when working in the securities, conveyancing and divorces department. She enjoys taking the time to understand the client’s wishes when handling their most sensitive information. After only living in the local area for two years, Karen couldn’t imagine living anywhere else but Hervey Bay. Four-wheel-driving with some friends is Karen’s ideal weekend break – which we are avidly awaiting an invitation to! We couldn’t ever put a label on Karen’s office superpower because that would mean limiting her to just one, but depending on the day, the mood and amount of coffee consumed, Karen could be excelling in a variety of specialties, for example, she always knows when a phone is about to ring!
