Most Australians only use toilet paper to wipe after taking a dump. To me this seems a bit unhygienic - poo remnants are left behind on your arse not to mention potential skid marks on your undies later. You really need water to clean up.
Those of you who have travelled around Asia know how great toilet bidets are. So why aren't they standard in Australia? I'm not even talking about a fancy Japanese bidet. Just a simple hose gun would do.
Along with being more hygienic, this would also greatly reduce the toilet paper used and save money in the long run.
Austalia is more of an american colony rather than british colony these days anyway.
