Luxury Real Estate Agents Who Go Beyond the Sale

Experience bespoke service and strategic advice from trusted experts in high-end property and property development across Brisbane, Gold Coast and Byron Bay. North South Real Estate guides discerning clients through Australia's dynamic prestige markets, delivering exceptional outcomes in every transaction.

Going beyond the sale means the work that sits either side of it. An appraisal comes first, so an owner can decide whether to sell at all. Then a campaign built for the building rather than to a template, or a direct approach to the buyer already looking for exactly what you own. For owners who keep the property, the same office manages it afterwards.

Nik and Aika Seirlis, luxury real estate agents, Brisbane

A Boutique Luxury Real Estate Agency for Brisbane, the Gold Coast and Byron Bay

North South Real Estate is a boutique luxury agency with offices in the Brisbane CBD and on the Gold Coast, covering the corridor that runs from Brisbane through the Gold Coast to Byron Bay and Northern New South Wales, with international listings in Spain and Dubai.

Boutique means a principal on every file from the first appraisal through to settlement, a campaign built for the property rather than to a template, and the judgement to run a sale quietly when discretion will earn an owner more than a public launch.

  • Offices in the Brisbane CBD and on the Gold Coast, covering Southeast Queensland and Northern New South Wales
  • Prestige apartments, trophy homes and development sites in the region's most sought-after addresses
  • Sales, buyer representation, marketing, property management and development advice from the same team
  • Principal-led service from Nik Seirlis and Aika Seirlis on every engagement

Why Clients Choose North South Real Estate

Our clients return and refer us because we consistently deliver exceptional results in Brisbane, Gold Coast, Byron Bay, and beyond.

Much of our work comes from clients who have already bought or sold with us, and from the people they refer. In a prestige market, owners talk to each other, and a quiet, well-timed approach is often worth more than an advertisement.

  • Discretion first. A campaign is public only when a public campaign is what serves the owner
  • Direct access to buyers already looking in a particular building or street
  • One point of contact, from the first appraisal through to settlement
  • Advice on what to change before a launch, and on what to leave alone

Nik and Aika Seirlis: Prestige Property & Development Experts in SE QLD

As Selling Principal and Director of North South Real Estate, Nik Seirlis leads prestige sales, buyer representation and development advisory across Brisbane, the Gold Coast, Byron Bay and Northern New South Wales. He works alongside Aika Seirlis, and together they take each engagement from the first conversation through to settlement, whether it is a trophy home on the coast, a prestige apartment in the Brisbane CBD or a development site with its potential still to be realised.

Between them, Nik and Aika cover sales, buyer advocacy, prestige property management and development consulting, so an owner selling one property and buying or leasing another works with the same advisers throughout. Aika brings five languages to that work, which matters to buyers arriving from overseas, and both bring a record of results that runs the length of the corridor, from Brisbane's landmark towers to the Gold Coast waterfront.

What Our Clients Say About NSRE

  • Amazing Agent and Team

    ★★★★★Rated 5 out of 5

    As someone who's generally sceptical of real estate agents, I was genuinely impressed by my experience with Nik & Aika. From our first meeting, Nik demonstrated a deep and sophisticated knowledge of Riparian Plaza.

    What stood out was their strategic approach - rather than just listing the property, they provided targeted recommendations for subtle improvements that would maximise return on investment. Their in-house styling team presented my property at its best and their network of serious buyers proved invaluable.

    Before we even launched our official marketing campaign, Nik secured an offer that exceeded my expectations. It's refreshing to work with professionals who combine market intelligence with genuine personal investment in their clients' success. I can't recommend Nik & Aika highly enough.

    George S, Seller. Luxury apartment sale, Riparian Plaza, Brisbane CBD, QLD 4000
  • Quick and Seamless Off-Market Record Sale

    ★★★★★Rated 5 out of 5

    When Nik & Aika approached us on a Tuesday asking if we were interested in selling off-market, we knew they had a serious buyer. They have a solid reputation for working with high-net-worth individuals and completing deals. By Thursday evening we had a signed, unconditional contract in our hands.

    The whole experience was one of ease, competence and professionalism. The team made the process seamless, we were never rushed and most importantly, we were very happy with the outcome of our sale.

    Peter L & Clare E, Sellers. Penthouse style apartment sale, Riparian Plaza, Brisbane CBD, QLD 4000
  • Achieved Over $3,000,000 For Our Property

    ★★★★★Rated 5 out of 5

    We knew Nik and Aika after meeting them while we lived at Riparian Plaza. They seemed like a dynamic duo with a positive, "can-do" attitude.

    They proved to be very responsive to any of our requests, day or night, and worked to meet deadlines.

    With such an excellent result, we engaged them to sell a waterfront property we owned in Birkdale. Their drive, work ethic and enthusiasm achieved great results for our two transactions and we strongly recommend 'Team Seirlis' to anyone also looking to great results on the sale of their property.

Luxury Real Estate FAQs Answered by NSRE

What is a luxury real estate agent?

A luxury real estate agent works at the top of a market rather than across all of it: prestige apartments, trophy homes and development sites, where a campaign is often run quietly and buyers are approached directly instead of advertised to. At North South Real Estate that means Brisbane, the Gold Coast, Byron Bay and Northern New South Wales, two offices, and a principal on the file from the first appraisal through to settlement.

What makes North South Real Estate a luxury agency rather than a general one?

The book it takes on. North South Real Estate handles prestige apartments, trophy homes and development sites across Brisbane, the Gold Coast, Byron Bay and Northern New South Wales, with a strong record in Brisbane's landmark towers, among them Riparian Plaza at 71 Eagle Street, designed by Harry Seidler. Every file is handled at principal level, from offices in the Brisbane CBD and on the Gold Coast, with services that run from the appraisal to the marketing campaign to the management of the property afterwards.

Which areas does the agency cover?

Brisbane, the Gold Coast, Byron Bay and Northern New South Wales. The two offices sit at either end of that corridor, one in the Brisbane CBD and one on the Gold Coast, which is what makes it practical to run a Brisbane sale and a Gold Coast purchase for the same client.

How can a Gold Coast real estate agent assist in buying or selling a luxury property?

Working with a Gold Coast real estate agent who specialises in luxury properties can give you a significant advantage. A local luxury agent has in-depth knowledge of the Gold Coast's prestige suburbs, market trends, and pricing for high-end homes. They can provide insight into each neighbourhood, from beachfront estates in Mermaid Beach to penthouses in Main Beach, and identify which areas or property types best match your needs. For buyers, a Gold Coast luxury agent offers access to exclusive listings (including off-market properties that aren't publicly advertised) and can expertly negotiate on your behalf to secure a favourable price. For sellers, the agent will craft a bespoke marketing strategy targeting qualified affluent buyers, using professional staging, photography, and high-profile advertising to showcase your property's unique features. They'll leverage their network of luxury real estate agents and clients (locally and internationally) to maximise exposure. In summary, a Gold Coast luxury real estate agent provides local expertise, personalised service, and skilled negotiation, ensuring that whether you're buying or selling a luxury home, you achieve the best possible outcome with minimal stress.

Does NSRE offer international luxury real estate listings?

Yes. North South Real Estate (NSRE) has expanded into the international luxury property market. We proudly launched our international listings hub, now featuring world-class properties in Spain and Dubai. This expansion allows us to connect discerning buyers and sellers with opportunities both in Australia and abroad. Whether you are seeking a prestige villa on the Mediterranean, an architectural icon in Dubai, or want to market your property to an international audience, our team delivers a seamless experience. By combining local expertise with a global network, we ensure our clients gain access to the finest properties worldwide.

What is property development in real estate?

Property development is the process of subdividing or creating new buildings or improving existing properties in order to increase their value. It encompasses a wide range of activities, for example, buying land, securing the necessary planning permits, constructing infrastructure, building or renovating existing structures, and finally selling or leasing the finished product. Development can be residential (like new luxury homes or apartments), commercial (office or retail projects), industrial or mixed-use. It involves multiple stages from initial concept and design, through financing and construction, to marketing and sale. At NSRE, we offer development advisory services to high-net-worth investors and developers, providing guidance on finding prime development sites, project feasibility, design input, and marketing strategies for luxury projects. In essence, property development is about adding value through transformation of real estate, and with expert advice it can yield significant returns for those looking to invest or partner in development opportunities.

Do you offer prestige real estate and property management services?

Absolutely. We provide full-service prestige property management for luxury rentals and investment properties. Managing a high-end property requires specialised care and attention to detail. Our property management team ensures your luxury residence is maintained to the highest standards, preserving its value and appeal. We handle everything from securing and vetting quality tenants (e.g. corporate or executive tenants) to arranging bespoke maintenance, cleaning, and concierge services as needed. We understand that prestige real estate owners expect proactive communication and discretion, so we keep you informed with detailed reports while handling day-to-day issues seamlessly. By entrusting us with your luxury property management, you can enjoy peace of mind knowing both your property and tenants receive first-class service. The result is stress-free ownership for you and a premium experience for the tenant, which in turn helps achieve higher rental yields and long-term value growth for your investment.
