Prototype Uncrewed Air System delivery aircraft development
This project will develop a prototype Uncrewed Air System (UAS) for long-range delivery of packages in Australia.
The rise of drones for moving both people and parcels around the country allows Australia to look to the skies in an effort to tackle its transport challenges.
Some people only associate drones with UAVs – Unmanned Aerial Vehicles – undertaking activities such as aerial reconnaissance, photography, and mapping. Yet drones continue to improve in their capacity to carry heavier payloads further distances. This creates the opportunity for drones to play a key role in alternative transport and smart mobility initiatives, moving both cargo and passengers from A to B.
The ability to deliver parcels has opened up a range of new applications for drones, but the development of larger models designed to carry passengers challenges the traditional definition of UAVs.
The new generation of drones capable of transporting people are generally known as “passenger drones”, perhaps leaving the modern definition of drone as “an aerial vehicle without a human pilot”. As a result, Australia’s Civil Aviation Safety Authority (CASA) now uses the term RPA (Remotely Piloted Aircraft) rather than UAV when referring to drones.
Similar to autonomous vehicles on the road, autonomous passenger drones can be limited to ferrying passengers between fixed points, or else be granted a greater autonomy in order to carry passengers to any destination.
When it comes to transporting people, some passenger drones will be designed for short hops, while others such as the Ehang VT-30 Long Range Passenger Drone are designed to carry two passengers up to three hundred kilometres. This makes drones practical for carrying passengers to their final destination, or on just one leg of a multimodal journey, such as travelling from home or nearby “vertiport” drone landing pad to a transport hub such as an airport.
Drones come in a range of configurations, depending on the tasks they must perform, the distance they need to travel and the nature of their destination.
Fixed-wing drones look similar to an aeroplane and are designed for long endurance and fast flight speeds, and are capable of reaching high altitudes and carrying heavy payloads. They can run on batteries or combustion engines and are energy efficient thanks to the wings providing lift.
This makes fixed-wing drones well-suited to reconnaissance-style missions. While they are capable of carrying heavy payloads, one complexity is that they require a suitable landing strip.
To get back in the air, they generally require a catapult or hand-launching. This makes fixed-wing drones most practical for delivering goods between fixed points equipped with landing and launching facilities.
Single-rotor drones look similar to a helicopter, sometimes featuring a tail rotor to control direction and stability. Running on batteries or combustion engines, they’re also capable of carrying heavy payloads and travelling long distances.
Like a helicopter, the advantage of rotor-based drones is the ability to hover, as well as perform vertical take-off and landing (VTOL). This makes them more practical for delivering goods to various locations which don’t have landing and launching facilities.
Single-rotor drones tend to rely on long blades, which can present safety issues when operating around people. Reliance on a single rotor can also create stability issues in rough weather or during rough landings.
Multi-rotor drones such as quadcopters run on batteries and support shorter flight times and smaller payloads. They also tend to be considerably more affordable and easier to operate than fixed-wing and single-rotor drones.
The increased stability of multi-rotor drones makes them well-suited to aerial photography, as well as flying and landing in challenging conditions. They offer the benefit of vertical take-off and landing, with their smaller blades making them better suited to operating in confined areas and around people.
Fixed-wing hybrid VTOL drones aim to offer the best of both worlds. Running on batteries or combustion engines, they can carry heavy payloads and travel long distances, plus they offer the benefit of vertical take-off and landing. Relying on multiple small rotors improves safety and stability in confined areas and around people.
While they are not perfect at either hovering or forward flight, this combination makes fixed-wing hybrid VTOL drones well-suited to delivering parcels. Amazon and Google currently use them for parcel delivery in urban areas.

When it comes to deliveries, drone transport offers a range of potential advantages compared to traditional delivery methods.
Taking to the air can reduce delivery times compared to travelling by road, thanks to the ability to take a direct route and avoid congestion on the roads. This is particularly advantageous when it comes to time-sensitive deliveries, such as hot food. Avoiding the need to employ drivers also helps delivery companies reduce labour costs.
Relying on battery-powered drones rather than delivery vans with combustion engines delivers environmental benefits. Staying off the roads also helps reduce traffic congestion, which offers a range of flow-on effects for road users from decreased travel times to reduced fuel bills and carbon emissions.
When it comes to long-range deliveries, drones offer the ability to access hard-to-reach locations, particularly thanks to vertical take-off and landing capabilities. This offers more accurate delivery of supplies than relying on aerial drops.
When it comes to transporting people, drones can also cut down on travel times and avoid road congestion, particularly when travelling to busy areas. Eliminating pilots reduces labour costs, while handing control over to autonomous systems is potentially safer than allowing consumers to pilot flying vehicles.
Taking to the skies is not without its challenges as drones vie to be part of Australia’s transport mix.
Capacity limitations around the bulk and weight that drones can handle will continue to make some deliveries impractical – whether they be single large items, or a large collection of small items. The fragile nature of some products will also make them unsuitable for drone delivery.
Considering a drone’s capacity challenges, the economics (in terms of both money and energy usage) of relying on drones to make small deliveries across a populated area will not always stack up against loading those parcels into a single delivery truck. Hybrid drone/truck last-mile delivery planning offers the potential to optimise drone usage.
Over-reliance on drones in highly-populated areas could also contribute to local air traffic congestion. As with road congestion, this could make drone usage less attractive by increasing travel times and energy consumption, while also increasing the likelihood of collisions and other accidents. Drones also present a risk to wildlife.
Meanwhile, weather conditions such as wind, rain, snow, and fog can hamper drone flights. Extreme temperatures can also impact their performance. In different regions of the country, weather conditions will limit the ability to depend on drones as a reliable delivery method during different parts of the year.
Drone also present safety challenges, particularly when flown near people, over built-up areas and potentially in close proximity to other drones and flying vehicles. There are also public acceptance issues when it comes to noise pollution, with Australian drone delivery trials sparking some complaints.
These safety and reliability concerns are even more important when it comes to passenger drones, considering both the safety of onboard passengers and that of other people in the vicinity, including other aircraft passengers. Placing vertiports in populated areas will also create noise issues and regulators will need to strike the right balance between safety, public convenience and innovation.
The Civil Aviation Safety Authority (CASA) has issued regulations for both recreational and commercial drone operators in an effort to keep Australia’s skies safe for all.
Depending on the weight of a drone and where they are flying it, commercial operators require operator accreditation or a remote pilot licence. Additionally, all commercially-flown drones must be registered, regardless of weight.
Drones must avoid prohibited and restricted airspace, plus those weighing more than 250 grams cannot fly within 5.5 kilometres of a controlled airport (which generally means an airport with a control tower). They may be operated within 5.5 km of a non-controlled airport or helicopter landing site, but only if they remain outside the airfield boundary and there are no crewed aircraft flying in the area. If a crewed aircraft is approaching or departing, the drone must land as soon as safely possible.
As a general rule, drones must not fly in crowded areas and must stay at least 30 metres away from people. They must not fly over or above people at any time or at any height, for example over a crowded beach, busy road, sporting event, concert or wedding.
An altitude restriction of 120 metres applies and drones can only be flown during the day with the operator maintaining line of sight with the drone. Operating drones above this height and/or beyond visual line of sight (BVLOS) requires additional CASA approval, which includes a risk assessment.
In addition to CASA’s rules, different states also have additional rules around drone use.
While many of the early commercial drone use cases revolved around aerial reconnaissance, the ability to carry and deploy heavier payloads has opened up a range of transport applications.
Making urgent deliveries such as medical supplies to remote or otherwise inaccessible regions makes the most of drones’ advantages compared to other forms of transport. Australia’s Swoop Aero, which provides medical drone deliveries in Africa, has launched a program in Australia with TerryWhite Chemmart to deliver pharmacy goods to rural Australian communities.
Drones can also be used for pathology deliveries, with Swoop Aero providing direct delivery of samples from local medical or pathology centres to hospitals and testing laboratories.
iMOVE is also involved in plans to develop and trial custom-made, state-of-the-art medical drones with a flying range of up to 250 km, to be used for the delivery of medicine in the Northern Territory.
The speed and convenience of drones also make them attractive for delivering online shopping. Wing Aviation, owned by Google, has been trialling drone deliveries in Canberra and Brisbane’s City of Logan, which includes a partnership with online food ordering company DoorDash. Wing Aviation launched a fourth location in the Gold Coast suburb of Ormeau, in a “store-to-door” partnership with Coles.
As part of Wing Aviation’s BVLOS approval, CASA has permitted it to operate drones in closer proximity to people than its regulations normally allow. They don’t land at customers’ homes, instead they lower deliveries on a seven-metre cable and leave them on the ground.
Other drone operators globally include Antwork, Flytrex, Manna, Matternet, Skyports, and Zipline.
Along with business-to-consumer deliveries, drones also have the potential for business-to-business deliveries and intra-business deliveries as part of supply chain logistics.
When it comes to carrying passengers, the applications for drones can be divided into air metro, air taxi and private.
Under an air metro model, Drones could provide low-capacity public transport services along scheduled routes between major destinations where the advantages of drones outweigh those of road transport.
Air taxis could provide an on-demand service, either providing door-to-door service or travelling between vertiports. In the latter scenario, passenger drones could provide one leg of a multimodal journey. Uber has chosen Melbourne as the first site outside the US to trial its Uber Air electric autonomous helicopter service.
Passenger drones could also offer private transport, similar to private helicopter ownership but without the need to employ a pilot. Again, they could travel door-to-door or between vertiports.
Applications for drones in the transport sector look set to scale, particularly driven by disruptive businesses which are looking to expand their services and improve customer experience whilst reducing their reliance on human labour.
Amazon, the world’s largest online retailer, has begun drone delivery trials in the US and has pledged to deliver 500 million packages each year by drone from 2030. It is working towards the goal of delivering orders by drone in less than 60 minutes.
Uber has previously stated that Uber Air trial cities Melbourne, Los Angeles and Dallas will require around 1,000 autonomous helicopters and 83 “skyport” landing pads per city in order to be effective. It is working with half a dozen aerospace companies on prototype craft to be used as part of its air taxi service.

From the Validating the benefits of increased drone uptake for Australia project, iMOVE produced the final report, The Future of Drones in Australia.
iMOVE is also involved with a PhD considering hybrid drone/truck last mile delivery planning for e-groceries, plus it has undertaken an empirical analysis of drone ecosystems in 4PL logistics. In conjunction with RMIT, iMOVE has investigated a novel method of using a long tether and a medium fixed-wing drones to deliver multiple packages at various weights.
In terms of health, iMOVE is involved in Australia’s first drone trial for medical supplies in remote areas, in partnership with the NT Government Department of Health and Charles Darwin University (CDU).
Additionally, we’re readying Australia’s next generations of experts and practitioners to help make Australian skies prepare for drone transport via our Undergraduate Student Industry and Industry PhD programs.
As mentioned above, iMOVE, the Northern Territory Department of Health, and Charles Darwin University are conducting a trial looking to deliver medicine to remote NT communities. It’s important work as these communities have an urgent need for this service, and this trial sees drones take on the issues of long distance, harsh and variable weather, and strict air safety regulations. The success of this trial opens up this form of delivery to the many sparsely populated regions of Australia.
Taking a very much wider view, or report on the Future of drones in Australia report takes a snaphot of what’s happening in the drone space now, what trials are taking place, and what State, Territory, andFedral governments can support the future growth of drone use. Key benfits and challenges are outlines, and recommendations are made.
This mode of transport can both save and make money, and grow employment. All of this in a wide range of sectors, including advanced air mobility, environmental management, freight and last-mile delivery, public services, agriculture, mining and resources, construction and recreation, and entertainment.
