The last one is Geranium molle, the Dovesfoot Cranesbill or Dovesfoot Geranium is an annual herbaceous plant belonging to the Geraniaceae family, right?
Can u tell me what r they and thank you!
The first one might be Echium vulgare, Vipers Bugloss, but I have no idea if it occurs in Australia.

I don't know the name unfortunately, but the first one looks identical to a yellow flowered weed in Asteraceae family that I get all over my garden.
