5 snakes in Australia - ID requested, please

Hi all,

Last november, I've encountered several snakes. Could you please help me identify these creatures? I tried to catch them on camera.

Not all of the pictures are showing the entire snake, but I hope it's clear enough to analyze.

Myself I thought that these are
1. Eastern Brown,
2. Juvenile Eastern Brown (due the banded stripes, green with black) or a Coastal Taipan?
3. Tiger Snake
4. Tree Snake
5. Copperhead or a Tiger snake (this last one we saw in the Blue Mountains by the way).

Thanks very much in advance!
Regards, Schapie.
