Gilmour Space Technologies
Australian space company
Gilmour Space Technologies is a venture-funded Australian aerospace company that is developing hybrid-propellant rocket engines and associated technologies to support the deployment of a low-cost launch vehicle.
Founded in 2012, Gilmour Space's function is to provide space launch services to the small satellite market using Australian-built Eris orbital rockets, launched from Gilmour's private spaceport in North Queensland. The company also intends to offer a ride-sharing service, in addition to a modular G-Sat small satellite bus/platform.
The maiden flight of Eris Block 1, which was unveiled by Prime Minister Anthony Albanese as Australia's first sovereign orbital rocket, took place on 30 July 2025 from Bowen Orbital Spaceport at Abbot Point, Bowen, resulting in failure after 14 seconds of flight.
Gilmour Space has long-term ambitions to develop a range of Eris-class launch vehicles capable of carrying larger satellites/payloads into low Earth orbits, and eventually provide space access for crewed orbital missions.
Founding
Gilmour Space was founded in Australia 2013 by brothers Adam and James Gilmour.
The company's first project in 2013 was to design and manufacture high-fidelity spaceflight simulators and replicas for a number of space-related exhibits and the Spaceflight Academy Gold Coast. It began its rocket development program in 2015; and within 18 months, successfully launched Australia and Singapore's first privately developed hybrid test rocket reaching an altitude of 4–5 km in a 90 seconds flight.
Since then, the company has been developing larger rockets, including the One Vision suborbital rocket and Eris orbital launch vehicle.
Investors
As a leading New Space pioneer in Australia, Gilmour Space is backed by some of the country's largest investors, including Blackbird Ventures (which led its Series A fund raise) and Main Sequence Ventures (which led its Series B raise); as well as international investors like Fine Structure Ventures (Series C) and 500 Startups.

Why this record matters
The phrase “australian space company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q28448211. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2012, 2025, 2013 and 2015.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
