Cameron Pilley, Donna Lobban and Christine Nunn all have the opportunity to win two titles as the showpiece games were booked at the Carrara Squash Centre.

In the men's doubles, Pilley teamed up with Ryan Cuskelly to defeat Colombia's Andres Herrera and Juan Vargas of Colombia in the semi-finals.

The top seeds and reigning Commonwealth Games champions saw off the third seeds 11-5, 11-7 in 23 minutes.

They will now play second seeds and compatriots Zac Alexander and Rex Hedrick in the final after they knocked out South Africa's fifth seeds Jean-Pierre Brits and Christo Potgieter 11-9, 11-4.

"I thought we played really well, we probably lost a bit of concentration in the second where the ball got a little bit dead after the first game but overall we're very confident," Cuskelly said.

In the mixed doubles, Pilley and cousin Lobban, the top seeds, won their semi-final 11-7, 11-9 against fellow Australians and fourth seeds Alex Haydon and Alexander.

Their reward is a final meeting with third seeds Nunn and Ethan Eyles, who accounted for Colombia's second seeds Catalina Pelaez and Matias Knudsen 11-10, 11-6.

Both of the losing semi-final pairs received bronze.

The women's tournament consists of a five-team round-robin with the top two pairs then contesting the final.

Top seeds Lobban and Nunn and second seeds Sarah Cardwell and Jessica Turnbull have yet to play their group match but are guaranteed to finish in the top two regardless of the outcome of that game tomorrow.

All of the finals will take place tomorrow in the 2018 Commonwealth Games host city.
