Biofuel as a side venture that makes a bit of profit / saves on a bit of fuel outlay has always been a thing in Australia also.

Currently, off the top of recent memory:

* Australia is exploring using canola to produce sustainable aviation and renewable diesel fuels, potentially creating 7,000+ jobs by 2030. - Landline (June 2025) https://www.youtube.com/watch?v=fIwsfxK6jw0

* North Queensland graziers are trialling a 10-hectare pongamia plantation to run alongside livestock. (July 2026) - https://www.abc.net.au/news/2026-07-19/pongamia-tree-aviatio...

* Agave is climate change resistant and has promise beyond just tequila - (May 2026) - https://www.abc.net.au/news/2026-05-23/australia-agave-farmi...

* Adelaide will turn 600,000 tons of forest waste into 140 megaliters of jet fuel per year, enough for 4.5M passenger seats. - (July 2026) - https://www.youtube.com/watch?v=z0u91oQ-hjY

The relative perspective on 4.5M passenger seats is that at one point in the recent past (possibly pre COVID) there were ~ 1M passengers in the air globally at any random time.

On the business investment and development side there are several operators, eg: JetZero Australia - https://jetzero.com.au/projects
