Australia will be looking to lift the trophy once again after they were defeated by New Zealand in the semi-final at Kitakyushu and had to settle for a bronze medal. 

During the tournament, they were also without Ellia Green and Sharni Williams who also suffered injuries during the Commonwealth Games.

Speaking to Rugby.com.au, Evania Pelite said Caslick was going well.

"She had a bad head knock but she is preparing really well," she said.

"Hopefully we will have her back out there in Canada."

If Australia were to be crowned Champions at  Langford it would give them an unassailable lead in the World Series standings with one leg remaining.

Currently, New Zealand are nipping at their heels as they sit only six points behind Australia so a win would put them in a good position to with their third title.

"A performance in Langford would really set us up to secure that (top) spot," Pelite said.

"Obviously we have Paris afterwards but if we can get out there next week and hopefully come away with the win, it will definitely help us secure that."

The Langford 7s will take place between May 12 and 13.
