Australian opening batsman Matthew Hayden has reportedly decided to retire from international cricket.

News Limited is reporting on its websites the Queenslander has decided to quit after 103 Tests and has been mulling over his decision after being dumped from Australia's Twenty20 and one-day squads.

Hayden is expected to receive a rousing farewell at Tuesday night's second Twenty20 match between Australia and South Africa at the Gabba.

The 37-year-old's exit comes after a tough summer where he averaged just 19.5 with the bat during Australia's 2-1 series loss to the Proteas.

His 39 at the SCG last week was his highest score in five Tests.
