australia dividend withholding tax is 30%, but you have to see whether your stock or business pays franked, unfranked or partially franked dividends.
Franking is like our one tier taxed system and partially frank is like Singapore's old tax system where you are taxed 2 times, but the second time you can claim back through tax credit. I still have my AREIT tax credit form somewhere.
Franked dividend means that the company is taxed at corporate level once at 30%, and the dividends should not be taxed again. fully franked dividends you do not need to pay dividend withholding tax
A totally unfranked dividend is like receiving a dividend without tax on it (gross dividend) this is subjected to dividend withholding tax.
The % of dividend withholding tax differs. the official is 30%, but because some countries have a double taxation arrangement with Australia, the dividend withholding tax is 15%.
Some business that set up their sub companies in a certain way, have some of their money return as "capital reductions" which are not subjected to tax. if you have a mixture then your aggregate tax would be somewhere like 11%. perhaps frasers logistics and industrial trust is one of them.
How do you know whether dividends are fully franked, unfranked or partial? you will have to look up on your own. as an example Telstra is fully franked. Most of the australia REITs are fully unfranked. This means the div you need to deduct the withholding tax to see if its worth it.
dividend withholding tax is with respect to where the business is domiciled. this slide extraction is from a FLT report:
