I'm not sure how this factors into the transit situation, but I would say odds for transit in January 2022 are pretty good as long as the virus situation improves in the origin country (or remains steady in low risk places like AU/NZ).
At the present time only PRs and valid visa holder can enter. They also have to fulfill entry requirements of vax, Q arrangements, pre-departure -ve test result, and not having been certain countries within the 21 days pre arrival.
Hope for the best and plan for the worst.
