In recent weeks, I've been finding massacred fronds on the manferns in my garden. (Sorry about the duplicate photo and photos in the wrong places. You'd think that'd be easy to fix. )
The only thing I've noticed, was on top of another manfern trunk (that hasn't had fronds eaten) - piles of...small possum poo? Maybe ringtail?
I wondered about large rats, but the scats are fairly round on the ends, so maybe not. Any ideas?
