Australian rugby legend Michael Lynagh was released from hospital on Tuesday, two weeks after a stroke that at one stage saw him classed as critical.

"Almost exactly 2 weeks after my stroke, I have been released from hospital," Lynagh tweeted.

"A long way to go, but a big step in the right direction."

The Royal Brisbane and Women's Hospital said in a short statement that the 48-year-old and his medical specialists will address the media on Wednesday.

Lynagh, a former Wallabies captain and World Cup winner regarded as one of the sport's all-time greats, was rushed to hospital with headaches and blurred vision.

Doctors said at the time he suffered a "cerebellar and occipital lobe stroke" due to a blocked vertebral artery and it had affected his vision, co-ordination and balance.

Lynagh, who is based in Britain and was in Australia on a visit when he fell ill, won 72 caps for Australia in the 1980s and 1990s as well as having a distinguished state career for Queensland.

He was part of Australia's Grand Slam winning team in 1984 and a key player in the Wallabies' 1991 World Cup win.

Lynagh captained Australia from 1993 to 1995 and held the world points scoring record when he retired with 911. He also held the world record for most conversions (140).
