Nothing pisses me off more than when a team doesn't wear all their jerseys in a season...and that's what the Sharks are doing right now. Why the fk would you make a jersey and not wear it? Sharks seem to be succeptible to this as they didn't wear their Kokoda jersey in 2020. Extremely annoying...
I think the current situation is a fair excuse to not wear it. They may have decided to wear it late in the season, but once the relocation of the competition happened, it was easier for them to only take the home set to Queensland as it would mean less baggage to have to bring along.
The Kokoda one would have been very similar, planned to be worn at a special match during the season. Games were relocated so they didn't want extra baggage as well as and no crowds to have a proper commemoration, so don't wear it.
