Ulster full-back Adam D'Arcy has agreed a new two-year contract which will keep him at Ravenhill until 2013.
The 25-year-old from Australia signed a one-year deal with the province last summer after impressing coaching staff during a two-week trial.
D'Arcy, whose grandfather is from Tipperary, has been a regular at number 15 for Ulster ahead of Jamie Smith who is moving to Newport Gwent Dragons.
Irish-qualified D'Arcy played for Manly in Sydney before moving to Belfast.
"I am grateful to Ulster for giving me a chance and have enjoyed my time here," said D'Arcy.
"I have learned and experienced a lot. I am really looking forward to the next two years.
"We have shown this year that there is a lot this team can do. We are heading in the right direction and I want to be a part of that.
"I have really enjoyed playing for Ulster, and with guys like Andrew Trimble and Rory Best who are international calibre players."
Ulster's Director of Rugby David Humphreys said D'Arcy had arrived as an unknown prospect but had become an important member of the team.
"He has certainly proved himself," said Humphreys.
"If we want to compete at the highest level we need depth and quality in our squad and we feel that Adam adds just that to our line-up."
