Quiet is always good when you have close neighbors. You really don't want to rock the boat unnecessarily, even if chickens are permitted, quiet is better
I know in my town the ordinance does not prohibit roosters, but it does specifically mention excessive noise and nuisance animals, so if I had a loud rooster and someone complained, I could be made to get rid of it.
Good luck with the new chickens. It should be fun. I have never had australorps but they have been on my wish list, they just were not available at the right time. They are popular for a reason and seems like they generally make good pets.
