Two goals from debutant Sam Ward helped England's men beat Australia 3-1 in the opening match of the Champions Trophy in India.
World champions Australia have won the tournament five times in a row.
Alastair Brogdon opened the scoring for England, before Ward scored two either side of penalty-corner specialist Chris Ciriello's goal for Australia.
Man-of-the-match Ward said: "I can say I've not played in many matches like that before."
"It does make it a bit sweeter getting the three points against such a good side - I've got a few Aussie friends back home but it's just good to get the win and it's been a great first day for me," he added.
England recorded their first victory over the Aussies in the event and are looking to end 2014 on a high after taking the bronze medal at the Commonwealth Games in Glasgow and finishing fourth at the World Cup in June.
Brogdon rounded goalkeeper Andrew Charter in the sixth minute to put his side ahead and, after England goalkeeper George Pinner made two important saves, Ward converted a rebound off the post for a half-time 2-0 lead.
Ciriello pulled one back with six minutes to go, but after England captain Barry Middleton cleared off the line, Ward sealed the win with the third goal, eventually given after a video referral.
Australia were without Jamie Dwyer, Mark Knowles, Kieran Govers and Joel Carroll through injury, with midfielders Liam de Young and Rob Hammond retiring.
Both teams played with black armbands in memory of Australian cricketer Phillip Hughes.
England play Pakistan on Sunday and Belgium on Tuesday in Pool A. Hosts India are in Pool B with Argentina, the Netherlands and reigning Olympic champions Germany.
