ChatGPT4 Makes this about your message:

The phrase you've shared contains a lot of Australian slang. Here's a translation:

"G’day!" - This is a common Australian greeting, similar to "Hello" or "Good day."

"How’s it going?" - This is asking how the person is or how things are going for them. It's similar to "How are you?"

"My ankle biter killed me yesterday." - "Ankle biter" is an informal term for a small child, likely referring to the speaker's own child. "Killed me" probably means that the child exhausted or overwhelmed the speaker with their energy or needs.

"I’m knackered." - This means the speaker is extremely tired.

"Might have to bail on the barbie." - The speaker is considering cancelling or not showing up to the "barbie," which is short for barbecue, a common type of social gathering in Australia.

"My mate lives out whoop whoop." - "Mate" is a friend, and "whoop whoop" is a colloquial term for a place that is considered remote or far away.

"Too far, can’t be fucked." - This means the speaker is saying the distance is too great and they can't be bothered or don't want to make the effort to travel it.

"I’m cactus." - This is an Australian phrase meaning they're done in, exhausted or at the end of their tether.

So a paraphrase of the whole phrase could be, "Hello, how are you? My young child really wore me out yesterday. I'm extremely tired. I might have to cancel on the barbecue because my friend lives in a remote place. It's too far away, I don't have the energy or motivation to go there. I'm completely exhausted."
