"We are certainly the underdogs," Williams said.
Egypt promised to be a tough match for the Kiwis in an Egyptian-ruled tournament after Marwan Tarek and Rowan Reda Araby won the men's and women's titles respectively.
"The girls will be going out and do what they normally do, prepare, warm up really well and we always give them something to focus on," Williams said.
"They might choose one part of their game that they will try to work on really hard."
The Kiwi team is made up of Rotorua's Camden Te Kani-McQueen, 18, alongside Kaitlyn Watts, 16, Anna Hughes, 18, and Anika Jackson, 15.
Williams said it had been a long week of individual events and now it was crunch time for the teams.
"They have all had a rest day and we got one to the final of the plate," she said. "Now we are really raring to go for this part of the event."
It was a case of repetition for the women's team as the girls continued their daily routine of training to prepare for each match.
"We get up in the morning, have our breakfast and go to the courts to work on what we need to work on for the day," Williams said. "Then we go back, have lunch and play again."
She said training had been going well so far, with no injuries.
The Kiwi boys and girls missed out on a top 16 spot in the individual events, and the pressure was on for the Kiwi women's team for the remainder of the competition.
"All eyes are on you more because you are in your own country," Williams said. "There is no doubt about that."
But Williams said her players were competitive, particularly 18-year-old Camden Te Kani-McQueen.
"Camden played one of the Egyptians in the individuals and almost got a game, so she knows that she can match it. She is certainly competitive."
Williams has played with Te Kani-McQueen's mother and NZ squash champion Susan Devoy and said the 18-year-old had a little bit of her mother's fight in her.
"Sometimes I look at her and I think it is her mother, some of her mannerisms," Williams said.
Te Kani-McQueen's father also played in the 1982 World Junior Squash Championships.
"I certainly see a little bit of both of them in her," Williams said.
The Rotorua teenager was the first of two Bay players to take to the court in the individual events.
She gained motivation from her mum and dad, saying she thinks about what her father Danny McQueen would say when she is on court.
"At training he would always be talking to me in the middle of hitting the ball and would say to me to get my length and go hard."
Her goal in the competition was to get above her seeding and playing her best on the court. She said playing in front of a home crowd was an advantage.
"I am trying to get my whole family to come so I feel comfortable."
