I just looked on Seek, the platform people mainly user here in Sydney, there is one job, outside panel beaters.

In Australia the Rust jobs are mostly crypto scam listings unfortunately.

I notice, outside of Sydney there a few. There seem to be a bunch of Binance jobs. Are they the ones that are scams? They look kinda wacky, the Rust job says "Who may apply Current university students and recent graduates who can work at least 4 days per week."

Maybe this is some way to avoid Australian salary regulation and pay $10 an hour?

There is very little jobs in Rust and as of recently almost nothing. A couple years ago it was mostly crypto but now only a few big companies are hiring for Rust.
