Five stars for Nik and Aika!
We had a wonderful experience working with North South Real Estate. Nik and Aika took the time to truly understand what we were looking for and were incredibly thorough in their search. Thanks to their hard work and dedication, they found us the perfect property for our needs. If you want a team that is professional, attentive, and delivers great results, look no further!
The service we received from Aika and Nik of NSRE was exceptional. We followed their informed and valuable advice on how to prepare our property and within days we were on the market and sold first day for a price beyond our expectations. Thank you guys for your talent and hard work!
Aika and Nik helped us every step of the way through the daunting process of buying our first home. We really appreciated their expertise and knowledge of the property. I grilled them with many questions to which they had a sensible and informed response for each. Thank you Aika and Nik!
North South Real Estate exceeded my expectations and delivered an outstanding result, achieving a record sale price for my unit. Nik and Aika were professional, knowledgeable and kept me informed throughout the entire process. They also generously provided a free valuation on another property in my portfolio, which was greatly appreciated. It’s also fantastic to see them supporting local community initiatives. I highly recommend North South Real Estate to anyone looking for exceptional service and results.
I had an amazing experience working with Aika and Nic while buying our first home. As first-time buyers, the process felt overwhelming at times, but they made everything so much easier to understand and navigate.
They guided us through the process from making an offer right through to securing the purchase, and we really appreciated how approachable and helpful they were every step of the way.
Their professionalism, responsiveness, and genuine care made the whole experience feel smooth and positive.
We’re very grateful for their support and would highly recommend Aika and Nic to anyone going through the buying process. Thank you both for making this such a memorable milestone!
✨ My experience with North South Real Estate & North South Prestige has been truly exceptional—an offering that sits well above the standard of traditional real estate services. From the very first interaction, Nik and Aika Seirlis demonstrated a rare blend of sophistication, efficiency, and genuine care, delivering a seamless and highly curated experience throughout.
✨ The apartment itself was nothing short of exquisite. Immaculately presented, fully furnished, and styled with an editorial eye, it felt akin to a private luxury suite—every detail intentionally designed, refined, and visually stunning, reminiscent of a high-end design portfolio.
💫 What sets Nik and Aika apart is their intuitive, concierge-level approach. Their attention to detail, responsiveness, and commitment to excellence create an environment where every aspect is effortlessly managed and every client feels truly prioritised.
This has, without question, been an outstanding experience defined by elegance, discretion, and impeccable service. I would highly recommend them to those who expect nothing but the best!

Thank you Aika and Nic.
I always wanted to live on Gold Coast. It was my dream of 30 years and guess what?
Dream come through ...
Thank you Aika and Nic ( North South Real Estate). Your help and professional, caring approach was beyond any expectation . Your prompt arrangements and non push approach was well received . Your experience and analyses , guided us to find exact location and not overbudget property that we love .
I am sure that we will be delighted to recomend your expertise to any of our friends.
Nik and Aika at North South Real Estate are exceptional!
Their support with every aspect of this purchase, from sourcing the properties through to settlement was top tier. It would be difficult to achieve these results without their guidance and support.
Nik and Aika now manage all of my properties, and achieve outlier results across the board, from tenant sourcing and selection, down to the finest of details.
Their team is available, informed, and always highly motivated. I can not recommend North South highly enough for the next stage of your property journey.
Andy, thank you for your kind words! Supporting you as your Buyer's Agents was a true pleasure. We’re always here for your next property journey and appreciate your recommendation more than you know.
I couldn’t recommend North South Real Estate and North South Prestige highly enough.
Aika was absolutely amazing. She was so lovely on the phone, incredibly professional, and genuinely caring. She took the time to run through all the information with me, answered my questions thoroughly, and even gave me helpful tips about making the move over to the Gold Coast. I never felt rushed or brushed off, just supported and listened to.
And after letting her know that I need some time to think about it, she followed me up and made sure that I had all the information.
If you’re looking for an agency that actually invests time in people rather than just transactions, I couldn’t recommend them more.
Aika and Nik achieved what we thought was a near impossible task but came through with flying colours for us. Their professionalism and attention to what we were after could not be faulted, every step of the way their attention to detail and keeping us in the loop was exemplary. We would highly recommend them to anyone looking to use them for buying or selling a property.
Nik and Aika really great couple to work with. Set them hard task to find property for us to meet all our requirements and they excelled far beyond our expectations. Totally use them again and highly recommend them to anyone.
I would like to express my gratitude to Nik and Aika for the superb job they did selling the existing and purchasing the new property in separate states for my elderly mother.
Everything was made exceptionally smooth with their prompt communication, can-do attitude and Nik's exceptional negotiating skills.
Nik and Aika are extremely professional in everything they do and also a very personable couple that went beyond to help wherever they could.
I recommend them to anyone looking for a seamless property experience and they are lovely to deal with. Thank you Nik and Aika.
Can not thank Aika and Nik enough for their expertise, patience and support through buying a house for wife, daughter and myself.
We were very quickly watching houses sprint away from our affordability. And knew with our first-home purchase we were going to face an incredible amount of competition (which we did!).
Both Aika and Nik really advocated for us, and because of that, we managed to secure our first home!
I look forward to working with them in future, and highly recommend for buying as well as selling. Thanks Aika and Nik!
Exceptional Dual Advocacy – A Seamless Experience from Sale to Purchase
From the moment we first spoke with Nik and Aika, things moved incredibly fast—on my first call Nik immediately answered the phone - tick one! In just a few days, our apartment was sold, and within a couple of weeks, we had found our new family home, ready to move in before Christmas which was our main goal. What felt like an overwhelming and stressful process—navigating the market, coordinating settlement timing, and managing the sale and purchase simultaneously—was made effortless thanks to their strong dual advocacy service.
Nik and Aika’s expertise, precision, and hands-on approach meant we didn’t have to do any heavy lifting. As a time-poor young family, we were worried the market was getting away from us, but they took care of everything and delivered a result we didn’t think was possible so quickly.
While they are the utmost professionals, it genuinely felt like we had known them for years. We got along so well, and they understood our needs immediately, which made the entire experience not only smooth but enjoyable.
They were always available to speak, responded promptly to every query, and truly understood the kind of property and lifestyle fit we were looking for. Their professionalism and dedication made all the difference.
We’ve built a partnership with Nik and Aika that we’ll continue to rely on in the future. Their guidance and support have been invaluable, and we know we’ll turn to them again for their expertise.
We couldn’t recommend their service more highly - Thank you Nik and Aika we have appreciated all your effort in achieving our dream this year!!
As first-home buyers facing intense competition and very limited housing availability under the new 5% deposit scheme, things initially felt almost impossible for us. That’s where Aika and Nik were absolutely fundamental. Thanks to their incredible guidance, we secured a wonderful property in just two weeks – and at a price BELLOW market value! This even helped the bank issue our final approval in just 1 day!!
I cannot recommend NS Prestige highly enough. Aika and Nik truly went above and beyond – even the real estate agents were surprised to see them attending every house inspection with us. Knowledgeable, patient, and genuinely passionate about getting you and your family the best deal, this dynamic duo makes buying a home – even in today’s wild, unpredictable first-home-buyer market – a pleasant and rewarding experience.
Thank you both so, so much. We owe our first beautiful home to your dedication and hard work!
