Nik Seirlis has sold 5002/71 Eagle Street in Brisbane’s Riparian Plaza for $4.5 million via private treaty after the first inspection, setting a per-square-metre record for the building.
The three-bedroom, two-and-a-half-bathroom apartment at 5002/71 Eagle Street in Riparian Plaza went under contract in early May with an unconditional offer and 19-day settlement. For the seller, the result delivered a $1.4 million uplift in four years — they had purchased the property with Nik in 2022 for $3.1 million.
The repeat client advantage
Nik’s client base is 86% repeat and referred business, and this campaign demonstrated exactly why. Both the seller and the buyer were past clients who already knew and trusted his approach.
Asked whether Nik has visualised the match-up, Nik responded, “We had multiple potential buyers from our extensive network, and we approached them privately once the property was listed for sale.”
That strategy paid off. While Nik had qualified buyers in mind, he still ran a full marketing campaign including North South Real Estate’s proprietary algorithm to get the property in front of dormant local, interstate and international buyers. Multiple qualified enquiries emerged, but the past client moved rapidly.
“They saw the opportunity and pounced with an unconditional offer, 19-day settlement at an outlier price, setting the per-square-metre record for the building,” Nik said.
World-class media meets Silicon Valley tech
Nik’s background as a technologist from Silicon Valley shapes his approach to high-end real estate. For this campaign, he created 360 interactive aerial views, 3D tours of the facilities and apartment, a one-minute premium video designed to drive next-step engagement, and exceptional photography including drone work.
The buyer recognised the architectural significance of what they were purchasing. Riparian Plaza was Harry Seidler’s final architectural masterpiece. The Royal Australian Institute of Architects named it Australia’s number one mixed-use building in 2007, followed by the Property Council of Australia in 2008.
A 20-year track record in one building
The $4.5 million result marks the third transaction in which Nik has been directly involved with this property. In October 2008, during the global financial crisis, he achieved an all-time record for the building at $3,355,000 — $905,000 more than the previous record sale for that apartment type. The purchaser later sold through other agents while Nik was taking a sabbatical, and the price dropped. When Nik returned, representing his client as a Buyer’s Advocate, he secured the same property off-market for $3.1 million for his current seller.
“For the past 20 years, my A+ Team and I have consistently achieved record results in Riparian Plaza, Brisbane City and beyond,” Nik said.
Location appeal
Riparian Plaza sits on Brisbane’s Eagle Street waterfront, a prime CBD precinct with landmark views over the Brisbane River and Story Bridge. The building is within walking distance of Howard Smith Wharves, the City Botanic Gardens, Queen Street Mall, and major public transport connections.
What made this campaign work
Nik’s advice for other Riparian Plaza owners considering a sale is straightforward: trust our experience and process, and invest in presentation and marketing.
“The seller took guidance from us, executed on suggested improvements to make the property peak-worthy and invested in recommended marketing strategy, which attracted high-net-worth local and out-of-area buyers,” he said. “The results speak for themselves.”
Nik describes his approach as matchmaking rather than forcing a sale — attracting the right parties to the property rather than pushing for any transaction. That philosophy, combined with his tech-driven marketing and deep client relationships, has delivered consistent outlier results across two decades in the same building.
