UASE Expo ran in Shenzhen from 21 to 23 May 2026 (Shenzhen Convention and Exhibition Center, Futian). It is a China low-altitude and UAV trade floor, not an Australian procurement show. Treat everything below as what the aisle was selling, then ask what has a path here. Australian timing for hydrogen airframes is unannounced. Say that once.
Hydrogen: endurance on the stand, logistics on the job
Hydrogen cells were a draw because endurance is the one number lithium enterprise kits still lose on. A Matrice 400-class flight is still in the neighbourhood of an hour depending on payload. Hydrogen exhibitors were selling multi-hour jobs: long feeders, big leases, fewer battery swaps.
The constraint that actually matters for an Australian crew is not the cell on the poster. It is refill. A remote pad, a moving work front, or an emergency callout does not magically grow a hydrogen truck. Depot-return inspection can plan for it. Fly-in fly-out survey mostly cannot, not yet.
We are not quoting hydrogen airframes as a stock line. If long endurance is the genuine bottleneck on your route, we will say so and map it against lithium plus extra aircraft, a dock, or a wait. Demo minutes from Shenzhen are not a tender spec.
CASA-aware as always. Nothing on that floor is "approved" for your operation because it looked finished under halogen.
GDU Tech: their aircraft, their payloads
GDU Technology is an industrial UAV OEM: airframes in the S200 / S400E class, gimbals, a dock story, LiDAR of their own (PLI01). It is not a bag of clips that turn a Mini into a mapper. That is a different buying decision (new platform, new spares, new training) than adding a sensor to a Matrice you already fly.
We have not published an Australian field test and we do not list GDU on the store today. Watch the category. Do not migrate a DJI fleet on a booth demo.
Get3D: processing, not a new drone
Get3D Mapper is photogrammetry and mesh software (imagery in, DOM / DSM / OBJ-class products out, with a viewer alongside). That is the right problem: most crews already capture; they burn the week in AT and cleanup.
We have not run Get3D on a paid Mirrormapper job. It is not Landmapper (dock and farm operations) and it is not MapShare (browser delivery of a SHARE project). If you want a processing bake-off, say which camera and which deliverable. Until then it stays a name on the floor.
BY.TECH: already on the catalogue
BY.TECH (SD By Vision) is the one of these three we already put on Australian kits: specialised payloads, not a second aircraft OEM. Live examples include the LM20T methane detection system and the ST40 water sampler, scoped to Matrice 400-class fitment on quote. Their BYTECH software is the vendor's planning and device layer around those tools.
That is the software conversation we can have without inventing a partnership: payload, aircraft, AUSCORS, handover, export into the report you already owe the client.
What to do with a show like this
Hydrogen stays a watch item until refill is a line on your method statement. New OEM airframes stay a fleet decision, not an impulse SKU. Processing tools earn a bake-off or they stay a bookmark. Payloads that already have a handle on our store are the only ones we will spec this month.
Talk through the job if a corridor, a gas leak route, or a processing bottleneck is the actual reason you cared about Shenzhen. We will tell you what we can commission now.
