The English born Canaries goakeeper is hoping to impress Ireland boss Giovanni Trapattoni in the coming weeks with the aim of breaking into his squad
According to the Sky Sports, the 28-year-old goalkeeper was approached by the Football Association of Ireland (FAI) in September 2012 with a view to representing the Boys in Green and despite being born in England, the Canaries shot-stopper has since expressed his desire to play international football for Ireland.
"It is one of my aims to try and break into the Republic of Ireland squad," Bunn told Sky Sports. "and if the opportunity arose I would definitely be interested in playing for them."
He added: "I think every player wants to play international football and play at the highest level and I am no different."
And Bunn is hopeful that he can stake a strong claim for the number one jersey with Aston Villa goalkeeper Shay Given retired and current number one Kieren Westwood struggling to break into the first team at the Stadium of Light.
He said: "I believe the goalkeeping spot with the Republic is up for grabs really since Shay Given retired. Keiren Westwood is first-choice at the minute, but he is not playing regularly for Sunderland.
"I now have a run of games in the Norwich team and it is a good time for me to show what I can do and impress hopefully," concluded Bunn.
