I came across some prints today ... I think they might be emu.

The photos were just taken with my phone, at close to midday, in sand, so the quality is not great. I neglected to include a scale - they're about as big as my hand, quite widely spaced, and lead to a water-filled rut in the track.
Any opinions? I had no idea there were emus around here.
(edit: I'm thinking less that they're emus.)
