Hi MEEmery,
Nice to find another Aussie here, welcome

What do you plan to do with your roosters? I don't have one but when I have a hen that is almost continuously clucky, I have a friend who breeds and shows chooks and she gives me some fertile eggs. We've had a couple of boys, but my husband gets too annoyed with their crowing so I'm not allowed to keep them

Fortunately my egg-giving friend will always take back the roosters

. Because all of her hens are beautiful breeds, she gets good money by selling them. I am very grateful to have such a friend.
All the best with your new brood, keep us updated on how you're getting on
