Its 1 for Oceania not 1.5 and pretty sure that its for 2026 not 2022.
1.5 as the below states:
Play-off tournament[edit]A play-off tournament involving six teams will be held to decide the last two FIFA World Cup berths,[17] consisting of one team per confederation (except for UEFA) and one additional team from the confederation of the host country.
Two of the teams will be seeded based on the FIFA World Rankings, and the seeded teams will play for a FIFA World Cup berth against the winners of the first two knockout games involving the four unseeded teams.
The tournament is to be played in the host country(ies) and to be used as a test event for the FIFA World Cup. The existing play-off window of November 2025 has been suggested as a tentative date for the 2026 edition.
