Wildlife Spotting

Any help is appreciated! I think I have narrowed it down to three different species: 1. Northern Laughing Tree Frog (Litoria rothii) [because] "A distinctive characteristic is the contrasting black and yellow markings on the thighs and groin [in both pics you can see a yellow dot on black in the groin]." (http://museum.wa.gov.au/explore/frogwatch/frogs/northern-laughing-tree-… ), 2. Rockhole Frog (Litoria meiriana) (http://museum.wa.gov.au/explore/frogwatch/frogs/rockhole-frog ), and 3. Rock Frog (Litoria coplandi) (http://museum.wa.gov.au/explore/frogwatch/frogs/rock-frog )
