Former Italy international and Northern Pride captain Ryan Ghietti has died suddenly aged 37, leaving behind his wife Stacey and their two children, Grace and James.

The Queensland footballer is being remembered for his contribution to rugby league across far north Queensland and on the international stage, where his field goal helped Italy qualify for their first World Cup in 2013.

A fundraiser has been established to support his family following what organisers described as a 'sudden and unexpected loss'.

Italy team manager Reno Santaguida paid tribute to Ghietti, whose representative career included selection in the Azzurri's 2013 and 2017 World Cup squads.

'It is with heavy hearts that we mourn the passing of former Italian international Ryan Ghietti,' Santaguida said.

'Ryan will forever hold a special place in Italian rugby league history, kicking the unforgettable field goal that helped send Italy to its first-ever Rugby League World Cup in 2013.

'More than just a moment in history, Ryan was a proud Azzurri whose passion, commitment and love for the jersey will never be forgotten.'

Born in Innisfail on July 22, 1989, Ghietti played his junior football for Innisfail Brothers before building a career as a versatile halfback, five-eighth and hooker.

He represented Italy in 12 internationals between 2011 and 2016, scoring three tries and a field goal, and was appointed Northern Pride captain for the 2016 season.

His Italian heritage gave him the opportunity to take part in the country's breakthrough World Cup campaign in 2013, alongside established NRL players Anthony Minichiello, Aidan Guerra and Kade Snowden.

Italy entered that tournament after a stunning warm-up victory over England.

Ghietti was among the squad's young playmakers whom former Australian international Craig Gower was brought in to mentor during the tournament, after a neck injury prevented Gower from playing.

The campaign was driven by pride in their heritage, with players receiving £200 [$390 AUD] a week to cover living expenses rather than match payments.

Away from international football, Ghietti built strong connections through the Innisfail and Redcliffe rugby league communities and Northern Pride.

The family fundraiser also highlighted the friendships he formed through the building industry and firefighting community.

'Following the sudden and unexpected loss of Ryan, a much-loved husband, dad, son, brother and mate, we are coming together to support Stacey, Grace and James as they face a future they never imagined,' organisers wrote.

They described Stacey as someone who had consistently supported others and urged the community to rally around her.

'Stacey has always been the person who shows up for everyone else, offering love, support and a helping hand whenever it's needed. Now it's our turn to show up for her.'

Donations are being sought in lieu of flowers to help with unexpected expenses and give Stacey time away from work to care for the children.

Organisers said the contributions would provide 'some financial breathing room as they navigate life without Ryan'.

'Every donation, no matter how big or small, will go a long way towards supporting this beautiful family,' the appeal states.

'If you can't donate, sharing this page is just as appreciated.'

Santaguida extended his condolences to Ghietti's family, friends and former teammates.

'Thank you for the memories, Ryan. You will forever be part of our history and forever in our hearts,' he said.

'Once an Azzurri, always Azzurri.'
