Ona Sydney

Farm-led coffee at the counter

The coffee is treated as farm work before it reaches the cup. Sasa Sestic, Founder and CEO of ONA Coffee, holds that line at Ona Sydney in Marrickville, Sydney. His role here sits inside a wider program: ONA Coffee as the roasting house, Project Origin as the sourcing venture, and Nucleus Coffee Tools as part of the same pursuit of better extraction and service. The room may read as a modern Australian café, but the discipline begins earlier, with decisions made at origin and carried through roasting, brewing, and the pass.

Sestic came to coffee after competitive sport, including a year with the Australian National Team in handball in 2000. That detail matters less as biography than as method. The café inherits a competition-trained way of thinking, where preparation, repetition, and tasting under pressure become part of daily work. His recognition as Australian Barista Champion and World Barista Champion in 2015 belongs to the same arc, but Ona Sydney is not built as a trophy room. It is a working showcase for a coffee company that treats sourcing, roast profile, brew recipe, and service as one chain of custody. How long Sestic has held this particular station in Marrickville is not something the house states.

A bar built around rare coffees

The coffee bar is the centre of the place. ONA Coffee uses Ona Sydney as a showcase for Australian specialty coffee, including rare coffees from farms known beyond Australia, and the structure of the service keeps the cup in close conversation with food. It has to carry the experience through extraction, aroma, texture, and temperature, without leaning on ceremony.

Sestic’s known signatures include Raspberry Candy blend, Raspberry Candy, and the signature drink he used for the WBC 2015 finals. Those names place flavour in the foreground, but the craft underneath is more exacting than naming notes. Source-first quality, sustainability, community, and the sharing of great coffee as widely as possible form the stated through-line across his ventures. At Ona Sydney, that philosophy has a practical shape: coffee selected with origin in mind, roasted by ONA Coffee, brewed for a room that expects the bar to lead, and paired with modern, locally sourced dishes rather than treated as an afterthought to brunch.

The room around the pass

The room carries the energy of a café that knows the counter is the main stage. Marrickville gives it a working rhythm: casual service, a lively floor, modern cooking, and a bar where guests can read the method in the hands. This is not a hushed dining room. It is a small, energetic place, with the pace of orders, grinders, milk, plates, and conversation moving around the same bench.

The food follows a modern Australian café grammar, locally sourced and built to sit beside the coffee rather than compete with it. That relationship is the point of the venue. Ona Sydney gives ONA Coffee a public room in which farm-led sourcing and cup-by-cup service meet the pass, and Sestic’s broader work becomes visible in ordinary service. At the bar, Raspberry Candy moves from signature roast to cup at Ona Sydney.
