I'm guessing someone else did the admin and you have been signed up to a Vic club. come back... we need you!
All the Australians have been listed as the one club for some reason. I entered as Newcastle. As you say probably easier for admin. Might have been easier still if we were all named Bruce.
At O-ringen (and the like) it is de rigeur to amalgamate a few little club (rep numbers) and put under the earliest in alphabet - gets earlier bus allocations, starts etc.... apparently. Go figure! glad you survived NZ in tact. You'll have gained a lot of experience which will show in the coming months.
I think OTH was randomly (or alphabetically in the order of Cusworth) designated as Bayside Kangaroos since we all ended up there. The Israeli runner last weekend ended up with my club!
