Speight, ACT Brumbies teammate Tevita Kuridrani and the Classic Wallabies will fly to Fiji next week as part of the ARU's Pacific in Union program to develop the sport in the region.

Speight hopes it is another step towards the Wallabies playing a game in Fiji in the coming years and believes it will help bridge the gap between tier one and tier-two nations.

Fiji has joined the National Rugby Championship this year and it is hoped the competition could be a stepping stone to creating a Pacific Islands team for Super Rugby in the coming years.

There were four players with Fijian heritage in the Wallabies squad to play against Argentina in Canberra on Saturday night, including NRL convert Marika Koroibete.

"We've played Fiji in Australia earlier this year and personally I would love us to take a Test over to Fiji," Speight said.

"People would come out in full force and pack out the stadium, especially with the amount of Fiji players in the Wallabies team over the past three years.

"There is a massive following from back home, so to be able to take a Test back some time would be a dream come true ... I can't really put it into words.

"But if we can't take a Test there any time soon, this is the next best thing and I can't wait to see the smiles on faces."

The Classic Wallabies trip has been partly funding by the Department of Foreign Affairs and Trade as the ARU looks to build on a pacific-region prgram it start five years ago.

Brumbies hooker Josh Mann-Rea will join Speight and Kuridrani, while Stephen Hoiles will lead the Classic Wallabies contingent to work with schools and host coaching clinics.

The Classics, which will boast Lote Tuqiri, Radike Samo, Morgan Turinui, Pat Phibbs and Mark Chisholm, will play against a Fijian side as an NRC curtain-raiser next weekend.

The Classics visited Cooma and Jindabyne last week as the organisation attempts to rebuild rugby's reputation and community awareness.

The Pacific in Union program, which is aimed at Fiji, Samoa, and the Solomon Islands, will reach more than 70,000 children and tapping into a rugby-mad culture

"We just want to go over there, help out and say thanks for supporting rugby," said Classics co-orinator Hoiles.

"We're just trying to get out to different parts of the country and the Pacific Islands to promote rugby and the Wallabies. That's what our aim is and we always want to do more."

The best part for Fijian-born Speight and Kuridrani is the pair will get to visit their villages, Lautoka and Namatakula, for family time and kava sessions.

It will be a brief break for the Wallabies duo, who will spend just three days at home before rejoining the Test squad for a tour to South Africa and Argentina.

"This is a chance to give back and that's what is so special about it," Speight said.

"We can take back some knowledge to feedback to players and coaches and Fiji. It probably won't be long enough for us, but it's better than nothing.

"It will be special to take the group to our villages and see where we come from. It will be pretty humbling, I will get to visit my mum and my village, so it will be fulfilling as well."

Speight, the grandson of former Fiji president Ratu Josefa Iloilo, has maintained close links to Fiji since making his Super Rugby debut in 2011.

He raised money and collected clothes for those affected by Cyclong Winston last year and is working with the Walk On Walk Strong cancer foundation.

Fiji has qualified for the 2019 World Cup and will play against the Wallabies in the pool stages.
