A second world netball title win for Diamonds' defender Mo'onia Gerrard has upped the ante for two Wallaby squad members, her brother Mark and boyfriend Dave Dennis.

Mo'onia, 30, was part of the team that pipped New Zealand by one goal in overtime in Sunday's final in Singapore, having already tasted world title glory in 2007.

Mark, 28, also went to a World Cup four years ago in his chosen sport, but played just a couple of minutes off the bench in one game against Japan, before a serious knee injury ended his involvement.

That was his 23rd and most recent Test appearance, but his international career has been revived after a strong Super Rugby season for new franchise Melbourne following a stint playing in Japan.

His performances, including those in the unfamiliar role of outside centre, earned selection in a 40-man squad for Australia's five pre-World Cup Tests.

Waratahs forward Dennis, 26, was one of seven uncapped players in that squad, though he did go on the Wallabies' 2009 Spring Tour.

Both men spoke to Mo'onia Gerrard following Australia's World championship win

"She didn't sound the best, but I could tell she was very happy and very pleased and I'm a very proud brother, so I couldn't be happier for her," Mark said.

"My parents are quite animated about how we should go this year for the Wallabies during the World Cup.

"It's going to be tough but I hope the opportunity presents itself for me as an individual."

Dennis, who can play lock, blindside flanker and No.8, said the traditionally tight and epic trans-Tasman netball Tests were becoming like rugby's Bledisloe Cup matches.

"I had a quick chat with her after, but she had other celebrations to worry about, I was down the line in terms of priorities," Dennis joked.

"There's no pressure, she's (more than) 50 caps ahead of me, so I've got a long way to go.

"But she's going well and hopefully I get a chance to do my part in the rugby side of things."
