I'm Calvin Stewart — a sales executive at Biller Property working with homeowners across Sydney's East and beyond who expect straight answers, real preparation and a result worth talking about — whatever the property, whatever the price point.
Every good sale starts long before the sign goes up. I spend my weeks on the phone and on the doorsteps of the Eastern Suburbs — which means when your home comes to market, I'm not starting a buyer search from scratch. I'm calling people I already know.
At Biller Property we keep things simple: honest appraisals, meticulous preparation, and negotiation that treats every dollar like it's ours. No theatre, no pressure — just a process that works and a phone that always gets answered.
Biller Property is one of the Eastern Suburbs' most respected prestige agencies — born and raised in the East, with deep local knowledge, world-class service and a record of exceptional outcomes delivered with integrity. From our Double Bay headquarters, a 24-strong team covers prestige sales, project and site sales, and property management across Sydney — strongest in the East, and proven well beyond it.
Being part of that team means every campaign I run carries the weight of the Biller name — and every buyer in their network is a phone call away from your home.
Every campaign I run is backed by the full Biller Property team — sales, marketing, buyer management and project sales working as one.
Founding Principal. Two decades-plus in Eastern Suburbs prestige — numerous building, street and suburb records, including ‘Boomerang’.
Works hand-in-hand with Paul across the East’s most desirable homes, with remarkable results in the multimillion-dollar market.
Bespoke campaign marketing — strategy, copywriting and digital — with exceptional attention to detail.
Eastern Suburbs local bringing deep area knowledge and strong client relationships to every campaign.
Matches buyers and sellers — often off-market — with calm confidence, market insight and Biller’s extensive database.
Two decades in business and marketing across Asia-Pacific; takes development projects from raw site to sell-out.
Construction Project Management (UTS); across the development journey and the prestige Eastern Suburbs market.
Civil-engineering background; site acquisitions across the East, from planning through to delivery.
End-to-end campaigns — strategy, styling, marketing and negotiation — shaped to your property and your timeline, not a template.
Quiet sales for owners who value discretion. A deep local buyer network means strong results without a single open home, when that's what suits you.
An honest, evidence-based view of what your home is worth today — no inflated numbers to win your business, no obligation to go further.
Patient, respectful guidance through the sales that carry the most weight — with the logistics, timing and family conversations handled with care.
Experience bringing neighbours and larger holdings to market together — unlocking value that individual sales can't reach.
Street-by-street knowledge of what's selling, what's coming, and who's looking — shared freely, whether you're selling this year or in five.
Properties we've featured on Million Dollar Listing's Instagram — and the campaigns I've been part of along the way.

My deepest networks run through the harbour and beach suburbs below — but a prestige-grade campaign isn't reserved for prestige postcodes. The same preparation, marketing and negotiation that sets records in Vaucluse translates to every home and every price point, wherever it is.
Our utmost satisfaction and gratitude for the exceptional service provided throughout the sale of our home.
Highly professional. He targeted our property, came to us specifically, and sold it at the price we asked — in under a week.
Calvin sold our property within 4 days getting us an outstanding result.
Over a number of years Calvin has always been pleasantly persistent in finding us the exact property we wanted — and listened to every single detail we required.
Thinking of selling — now or someday? Start with a conversation and an honest number. No pressure, no obligation.
