Things went from bad to worse for a north Queensland man who tried to fish a snake out of his pool.

The 54-year-old man was bitten on the foot by the unknown species of snake at his Proserpine home on Tuesday morning.

The man then went inside the house and fainted, injuring his head.

An RACQ CQ Rescue spokeswoman says the man was airlifted to nearby Mackay Hospital in a stable condition, where he will be treated.
