Similar size to some of the common eastern froglets I've seen there... Kind of assuming it's also one but being so different to any of the ones I've previously seen thought I'd upload the phone photos in case it's not... It wasn't calling and I hadn't heard anything calling.
I am happy to go with the plain dorsal pattern of signifera, but to be sure of any Crinia in this region it is, when possible, worth including an image of the belly to rule out parinsignifera
