Can anybody help me make sense of these trades?

I'm very new at this

Every five minutes (almost exactly) there's a trade in AVH (Avita Medical) for between 227 & 231 shares, worth about $46.

I know that splitting a huge order into smaller parts might attract less attention, but these trades are too tiny for that, surely?

Cheers

They are programmed trades. Some brokers use them to try to ensure they get a good average price for their trades and take out the human element.
They are very annoying.
