Mine are standard Australian, really.
Red bellied black snake - one in a pond in the mountains - it swam over to where we were bird watching, looked at us, then swam back to its hole and disappeared (as did we, quite quickly!) and the other about 100m from the house in bushland - sunning itself on a treestump. I thought it was a discarded bike inner tube from a distance - we were collecting fire kindling - but when we got closer and realised it was a snake we backed away slowly. It didn't move but was gone when we returned.
Kangaroos - lots - mostly danger to the car rather than us!
Huntsman spider, redback spider, white tip spider (no funnelweb yet, thank goodness!) - all standard.
Possum down our chimney into the house - not dangerous unless you try to grab it - we just ushered it out again.
Emu in a wildlife reserve - took my husband's hotdog out of his hand!
Goanna - they can be a bit scary when they tent-raid. Make more noises than you'd think, too.
Saw an adder in the UK once - again, sunning itself, beautiful creature! - but it disappeared when I went inside to get a camera.
