Appears same old same old, still no evidence, no cubs found, no road kill, not film or photos, just confabulation.
In a country so heavily populated and studied as this with CCTV covering every urban and many rural areas along with thousands of camera traps across the country we see what is there and don't see what is not. Maybe one could argue for one or two very secretive cats in very rural areas but a breeding population???
Consider, some of our best habitats are nature reserves and as such have minimal disturbance but maximum observation yet never a big cat is seem, why is this?
