A man who was stabbed in Sydney's east last year said "go on, f---ing stab me" then pulled the 20-centimetre blade out of his own abdomen and stabbed his assailant 11 times, fatally wounding him, court documents reveal.

Christian Hargrave-McKey, 30, had just left the Nelson Hotel in Bondi Junction with a friend on the evening of December 22, 2018 and bought some food from KFC when he saw Mark Thomas, 60, who had coincidentally left the same pub.

The pair spoke briefly on the footpath on Oxford Street before Mr Thomas put his bag on the ground and the men began pushing and shoving each other. Hargrave-McKey's friend also joined the shoving, and the men began shouting at each other.

The friend's girlfriend attempted to stand between Hargrave-McKey and Mr Thomas, but Hargrave-McKey pushed her out of the way and said, "The man is trying to kill you".
