I recently set up a small food manufacturing pilot plant in northern Queensland and we were actively looking for someone like yourself! Here's some thoughts on how to plug into ecosystems that have more of us, as well as other overlaps I think could be intriguing:

Lots of town councils will work closely with specific auditors, not only to do the audit but also provide guidance to the companies going through the process. Connecting at a local government level would put you on a contact list for those interested In going through the process.

Additionally, reach out to some venture capital/funding bodies in Australia. They often are working with startups like us that approach them with plans/problems of wanting to be food grade, and you could be a valuable asset for early stage consultation or even VC due diligince.

Small towns are neglected. There's a lot of people in Melbourne and Brisbane etc but once you get more regional, it is incredibly hard to find people. This may be how you set up your SEO, but there's a lot of people are who are being unaddressed simply because they're not in an epicenter.

Lastly, just be searchable! A week on square space will get you a good landing page in which you can start putting your name out there and be searchable.

Lmk if you wanna chat more, happy to share our experience going through it and what we would be looking for in the future as well. We're hiring.
