I need HELP. Just found a snake on my back porch in Queensland Australia. It's green with a yellow belly.

It could be a tree snake which is not dangerous, but on the other hand, it could be a green mamba, or some other time of highly venomous snakes! Dont go close now, we don't know!

Looking at pictures of snakes in Australia, it looks like there are only 2 candidates for your snake and both are quite venemous

The Tiger Snake which is a land snake and the Yellow-bellied Sea Snake. Here are descriptions on the first link and pictures on the second.

Please be careful and stay away from it.

Info here about many snakes, including a yellow-bellied water snake (green).

its just a green tree snake not venomis and they are very scitish so if you go with in just a couple of meters of it it should run away

that sounds like the old green and yellow belly

eye of jealousy there

if i was you i would get rid of it as quickly as possible

may God bless you

sounds like a pope's tree viper. leave it alone and leave through the back door

What do you need help with? Instructions on how to let it go on it's way?
