Former schoolboy sensation Hadley Tonga is set to light up Perth after being named in Australia's Rugby Sevens squad for the upcoming tournament at HBF Park.

Tonga turned down advances from NRL outfits the Eels and Dolphins in 2023 to sign a three-year deal with the Australian Sevens program.

Injuries have ensured his highly anticipated Sevens debut will now go ahead.

Australia men's coach Liam Barry has included the 19-year-old for the January 24-26 tournament in Perth.

The home nation sits a lowly eighth in the rankings after two events, and desperately need a good result in Perth to get their campaign back on track.

Tonga's inclusion is one of three changes to the men's squad that finished ninth in Cape Town, which followed their seventh-placed finish in Dubai.

Veteran Maurice Longbottom returns from injury to play his first match since the Paris Games, while Olympic reserve Josh Turner has signed a contract to return to the squad following the departure of star Nathan Lawson due to personal reasons.

Henry Paterson has been ruled out after picking up an injury in Cape Town, while Henry Palmer and James McGregor have been dropped.

"We are stoked to welcome back Josh Turner and Maurice Longbottom to the squad while Hadley Tonga is looking to debut in Perth and that's exciting for everyone," Barry said.

"Very few teams have a home tournament so the players know it comes with expectation and it's a great opportunity for us."

Australia's men have been drawn into Pool A for the Perth Sevens alongside Argentina, South Africa and USA.

AUSTRALIA MEN: Henry Hutchison (capt), Ben Dowling, Matt Gonzalez, Ben Dalton, Maurice Longbottom, Jayden Blake, James Turner, Sid Harvey, Aden Ekanayake, Hayden Sargeant, Josh Turner, Hadley Tonga, Michael Icely.
