Surprise competition leader St George-Sutherland is keen to keep the shocks coming when the McDonald's Women's Premier Cricket competition continues on Sunday with the last in a series of T20 matches.

The Slayers won just one game last year in finishing a distant last but have stunned rivals with an undefeated start to this campaign.

That winning run will be put to the test against Gordon at Harold Fraser Reserve.

In other matches, last-start winners Bankstown meet Campbelltown-Camden, Parramatta take on Universities and Penrith host Northern District.

St George-Sutherland skipper Cailyn Fountain is confident her team can maintain the rage.

"Others might be surprised by our start but I'm not at all. During the pre-season you could see how determined everyone was to turn it around," she said.

"The girls have really taken their opportunities this year and have thrived under pressure. 

"There's a real energy around the group and it's exciting to see how far we can take it.

"There are still a lot of rounds left in the season so we need to keep focused on each game as it arises. We can't look too far ahead."

The Slayers have been strengthened by the arrival of former WBBL star Rhiannon Dick and the impending return of Sydney Thunder keeper-batsman Tahlia Wilson.

"Rhiannon is not only a great player but is one of our leaders and Tahlia has been playing great cricket and will be a real asset," Fountain said.

"Having that sort of experience around the team will really benefit the younger girls within the squad."

St George-Sutherland and Northern District are the only unbeaten teams after five rounds of what has been a hotly-contested start to the competition.
