"I've lost 16 sheep between now and Boxing Day, and now they've taken water troughs," he said.
"I had one in each paddock, and I drove past and they were both gone.
"When you're losing 16 sheep, at $100 minimum each, and now... "
He said he's "just about resigned" to losing around 40 sheep a year to theft - something that has been going on for more than five years - but this is something new.
"I have all the gates padlocked, I would never have thought it."
Having paddocks padlocked is a "massive inconvenience" but it is what farmers have to do to slow thieves down, he said.
It comes with being on a road that a lot of people go up and down, he said.
"We seem to be at a point where people get out of their vehicles."
