The ATO in TR 2012/5 give a ruling on dividends which includes:
From profits (para 3);
From "mce-anchorunrealised capital profit of a permanent character recognised in its accounts and available for distribution" (para 4).
A properly structured TO imho would be able to include capital profits that would be able to be distributed as franked dividends.
