I have photography equipment that I used while working a media consultant. It was a 100% deductible business expense back then, I get a tax break every year as they continue to "depreciate". It's been a few years, I still do some photography on the side mostly portraits or headshots.

surely that depends on the type of company you have? If you have a personal company then I expect it is like that, if on the other hand you are incorporated the full purchase should be deductible, the reasoning of course is that a product you buy for a personal company is also used for you.

You are right, of course it's not 100% deductible. I am not advocating spending wildly on things you don't need for the business. If you have lots of revenue and not a lot of expenses, it makes sense to splurge on physical assets you can use and then expense and in the future sell. I.E. computers, networking equipment, storage, monitors, etc. Furthermore, it also make sense to spend on things that can help you grow the business like advertising, marketing, office space, employees. Again, better to spend and get the tax deduction, and have the resources that grow the business.

Try 50% if you are earning 30k a month, top tax rate kicks in at 180k per year in Oz.
