The trapdoor spider was hunkered down in its trap waiting for prey. It emerged once or twice but sprang out of the trap as a black beetle and a tiny orange fly? passed by. Although so fast I could not see detail I think it caught the beetle. last pic it seems to be holding something close. The trap was quite firmly pressed and well made with a hole of 15 mm roughly but today when I looked the hole seemed to be cemented over or firmly tamped down. It may not need a feed for a while or maybe its locked in with a mate,
The two big front facing eyes are a dead giveaway for Lycosidae. Mygals have a tight cluster (excluding Missulena) of tiny eyes on the cephalothorax, sometimes on a raised caput e.g. Hadronyche
