Australia's Sonja Newman and Tom Foster excelled as each added four golds to the home total in what is the fourth version of these Games - founded in 2014 by Britain's Prince Harry for injured, wounded or sick members of the armed forces and previously staged in London, Orlando and Toronto.

In the women's ISC category, Newman won the 50 metres and 100m freestyle, the 50m backstroke and the 50m breaststroke.

Foster, in the men's ISD class, replicated Newman's winning pattern exactly at the Sydney Olympic Park Aquatics Centre.

Hannah Stolberg of the United States won three titles in the women's ISB category, and in the men's ISB category Italy's Armando Iannuzzi also won a hat-trick of golds.

The women's 4x50m freestyle relay was won by the US, while the concluding mixed 4x50m freestyle relay went to the hosts.

More medals were won today in the powerlifting at the Genea Netball Centre.

The women's lightweight IP1 category was won by home athlete Sarah Sliwka, who took gold with a best of 67 kilograms.

Silver went to Francesca Rocca of France, who had a best of 55kg, with bronze being claimed by Britain's Abbie Kasparis, who achieved a best of 39kg.

Gold in the men's lightweight IP4 category went to Jordan's Ahmad Hashem Albarahmeh, who cleared a best of 127kg with his third and final lift.

The silver medal went to Kenny Guin of the US, who achieved a best of 124kg, with Britain's Lee Matthews claiming bronze with 122kg.

In the evening's heavyweight sessions, the home nation completed a full sweep in the women's IP3 class as Sarah Petchell took gold with 86kg, Tiff White silver with 80kg and Brigid Baker bronze with 75kg.

Britain's Jennifer Yarwood finished one position off the podium with 60kg.

The men's heavyweight IP6 title was won by Britain's Martin Tye by the narrowest of margins from Ukraine's Yevhen Oleksenko.

Tye's final effort of 206kg was just one kilogram better than his Ukrainian opponent.

Bronze went to Rob Hufford of the US, who lifted a best of 190kg.

After a day of round robin action in the men's wheelchair rugby competition at the Quaycentre, Australia secured a place against France in tomorrow's semi-finals, with the United Kingdom facing the US on the other side of the draw.

Australia's earlier 24-6 win over New Zealand was marked by one of those moments that makes this international event so special.

Just before the full-time whistle blew, the Australian team passed the ball to Kiwi player George Nepata and made sure he got across the goal line to huge cheers from the crowd.

Nepata, a tetraplegic after a military accident, is new to wheelchair rugby.

And because a team member dropped out, he had to be on the field for the entire game.

It was clear he was running out of energy, but when the Aussies surprised him with this moment, he punched his fists into the air and the joy was palpable.

"It was a very humbling experience and I will never forget it," Nepata said after the game.

"It took me by surprise, I just do my role out on the court and then out of nowhere all I could feel was everyone come up behind me and push me toward the goal line.

"It was awesome."
