Switzerland, meanwhile, are set to make their second World Cup appearance after previously appearing at the 2015 tournament.
Match preview
The Philippines are preparing to make their first appearance at a men's or women's World Cup after securing their place in Australia and New Zealand with a fine performance at the 2022 Asia Cup.
Knowing that a semi-final place would be enough to qualify, the Philippines finished second in their group to advance to the knockout stage, where they managed to beat Chinese Tapei on penalties to progress to the last four.
Although their tournament was brought to an end by a 2-0 defeat to South Korea, they could still celebrate their best performance at an Asian Cup and World Cup qualification.
As the lowest-ranked team in a group that contains New Zealand, Norway and Switzerland, Alen Stajcic's side will have to produce some of their best performances in the next three games if they are to trouble their opponents.
They do head into the tournament off the back of a positive run of form that has seen them win five of their last six matches.
Switzerland secured their place in Australia and New Zealand with a dramatic playoff victory over Wales in October.
After playing out a 1-1 draw in regulation time, the playoff encounter appeared to be heading to penalties until Fabienne Humm scored a 121st-minute winner to send her country to their second World Cup finals.
In their previous appearance at the tournament in 2015, Switzerland advanced to the knockout rounds, before they were beaten 1-0 by Canada in the last-16.
La Nati head into the 2023 World Cup in poor form, having failed to win any of their last seven games since beating Wales in Zurich.
They have at least proven to be a tough team to beat, with five of those seven matches finishing all square, including their final two warm-up games against Zambia and Morocco.
