The 20-year-old, who made 17 appearances on loan at Newcastle last season, has signed a one-year deal after negotiating a release from Croatian club NK Osijek.

Prso, the nephew of former Croatia international Dado Prso, spent time in both the Dinamo Zagreb and Bayern Munich academy systems.

Eligible to play for either Australia, Serbia or Croatia, Prso has made two appearances for Australia's Under-23 team and is currently in an Olyroos camp in Qatar.

"The experience that Luka already has at 20 years old - having played in Europe, internationally with the Australian team and last season in the A-League - shows the potential and ability that he has," Phoenix coach Ufuk Talay said.

Prso will link up with fellow Olyroos young gun Reno Piscopo at the Phoenix and said he was lured to join the club by the brand of football Talay has established durung his two seasons at the helm.

"Wellington have always been a club that plays good football and has amazing fans," he said.

"I saw last season the type of football the Phoenix were playing, and I thought they were a great squad with some talented players - like Piscopo - so I'm really looking forward to linking up with those boys."

Prso is expected to join the Phoenix squad in Australia in early November before the start of the new season later that month.
