prolly one of those things where wiki would be useful

here you go, easy as abc https://en.wikipedia.org/wiki/Australian_dividend_imputation_system

It's a bit like when your employer pays part of your pay to the ATO in anticipation of future tax. If the company distributes money they have already paid tax on you will have a dividend that is paid directly to you, plus an amount that has been paid in tax. Fully franked means the company has paid tax on the whole lot, partially franked means they only paid tax on a part of it. When you come to do your tax return the ATO will work out how much you actually owe (based on the tax rate for your income) and either ask for a bit more tax or refund the extra.

Fully franked you get a credit for entire dividend amount and can offset your tax with that credit.
