Australian advanced aircraft developer AMSL Aero has been put up for sale after it failed to secure enough capital to commercialise its vertical take-off and landing aircraft. The drone and plane manufacturer had previously raised more than $50 million from major investors including Telstra Super and Hostplus. Boutique advisory firm Allunga Advisory is now managing the sales process for the company.
Company and Technology Focus
AMSL Aero was focused on developing a vertical take-off and landing aircraft that could serve both drone and plane markets. The technology required substantial investment to move from design and testing toward commercial production, and it positioned the company within Australia’s emerging advanced air mobility sector. This capital-intensive pathway made the company dependent on continued backing from institutional investors and private capital sources.
Prominent Investor Backing
The shareholder register includes superannuation funds Telstra Super and Hostplus, along with Trevor St Baker’s St Baker Capital Partners and IP Group Australia. These investors participated in funding rounds that provided AMSL Aero with more than $50 million. Despite this support, the company was unable to secure the additional capital required to sustain its vertical take-off and landing commercialisation program.
Abandoned Equity Raise
In July 2025, AMSL Aero launched a $30 million equity raise with Allunga Advisory, but that process now appears to have been abandoned. The raise was intended to give the company enough runway to continue developing its VTOL aircraft and move closer to commercial deployment. Its failure left the business without the financial foundation needed to maintain full-scale operations.
Operational Scale-Back
AMSL Aero has paused its vertical take-off and landing business, while some hydrogen-power related projects continue under a reduced structure. According to two sources with knowledge of the matter, the company’s headcount has fallen from a peak of about 70 people to six ongoing staff members. A small number of contractors remain in support roles as the company works through the sale process.
Sale Process Underway
Allunga Advisory is running a formal sales process for AMSL Aero, seeking interest from potential buyers for either the business or its underlying assets. The exact structure of any transaction has not been publicly disclosed, and it remains unclear whether a buyer will emerge for the full company. This sale process follows the abandoned equity raise and a sharp contraction in the company’s day-to-day operations, representing a critical juncture for its future.
Sector and Market Implications
The company’s situation highlights the funding difficulties faced by advanced air mobility ventures that require long development windows and substantial capital. Even with support from prominent Australian superannuation funds and private investors, AMSL Aero could not close the gap to commercial readiness, illustrating the sector’s execution risks. The outcome may influence how investors assess similar deep technology aerospace projects across Australia and the wider region.
The sale of AMSL Aero marks a significant moment for Australia’s emerging advanced air mobility sector, given the company’s previous investor backing and technological ambitions. While some hydrogen-related projects continue, the future of its vertical take-off and landing technology now depends on the outcome of the sales process. The case underscores the capital demands and risks involved in bringing new aerospace platforms from development to commercialisation.
