They don't. Koalas give birth to live young. As marsupials, they give birth to extremely undeveloped young.
The only mammals to lay eggs are the monotremes, which include just platypuseses and echidnas.
The koala is a marsupial. Monotremes are egg-laying mammals, and koalas do not lay eggs, but give birth to live young.
Koalas do not have eggs. They are mammals, so they give birth to live young, and do not lay eggs. Fertilisation occurs internally, in the fallopian tubes. This is like what happens in other mammals, including humans.
