Since you live in Australia Chooks4life, I imagine that's it's tough to purchase medicines for ailing birds due to government regulations I suppose, or a costly trip to the vet. So, you have to resort to the next best effective treatments, nothing wrong with that. But I can assure you that living in the southern U.S., the humidity is horrendous and using the deep litter method is asking for trouble. The american scientist who recommended the deep litter method probably never had chickens located in the southern part of this country. As you mentioned, keeping the environment clean includes inside the coop. Post #14 explains what happens with the deep litter method. Been there, done that...I speak from experience.
Here's a link for you, please read post #3 and also the link in the same post.

X2. I never understood the extremism of letting filth build up, or trying to create some type of hospital environment. Neither is appropriate. The whole "deep litter method" is merely a newly wrapped marketing of the old built-up litter that was analyzed during World War 2 during the labor shortages that affected the farm industry. They found B-12 availability in the unchanged litter built up over time. Back then B-12 was not recognized for its benefits in poultry, so it was never an addition in feed mills. B-12 didn't start getting added to poultry feeds until about 1950. Now that it is, the speculated nutritional benefit of built-up litter serves no purpose.
The anti-coccidial effect of built up litter is real but not consistent since failure to control wetness in the litter, harboring an environment for mites, lice, parasitic worms, not adequate ventilation to remove the ammonia fumes which can damage a bird's respiratory system, creates more problems than benefits. Why perpetuate an environment for disease? Laziness? Wanting to be some trendy pseudo-hippie with the audacity to think he can "save the earth" and help create more government regulation to tax people out of business or their hobby?
There are some very wise old methods for proper keeping of poultry and possess a number of Pacific Poultrycraft magazines from the 20's and The California Poultry Tribune from 1897-1899 which speak of some old methods that kept birds at peak health. The build up of manure isn't one of them.
