The problem with investing in appreciating assets in a company is that there is no CGT exemption, and will always be taxed at 30%. You have very little flexibility in distributing those funds afterwards also.
A discretionary trust is a better option – with corporate trustee, as this gives you better options tax wise when distributing profits. As for getting the money out of the company – perhaps you could lend it to the trust at the lowest rate the ATO will allow?
Depending on if you are just wanting to purchase just +ve cash flow properties, use the Family Discretionary Trust.
If wanting to purchase both -ve and +ve cashflow properties it is ideal to use a Hybrid Trust.
Though not sure what exaclty your interest are, though if you like to invest into all types of investments, ideally again you should use a Multi-Sector Trust
A Family Trust, must run at a profit, losses are carried over into the next year and that you can not offset it against a lost. Which means taxs benefits are slightly different.
With Hyrbrid Trust, when you purchase -ve geared property you are runing it at a loss, thus mean you can offset this loss against another preforming asset or distribute all profits, so that the loss is minimal.
Any trust can carry losses-I beleive indefinitly until a profit is made.
Troyid, maybe you company shares can be owned by a discretionary trust. All profit could then flow to the trust and from there distributed elsewhere at the trustees discretion. (possibly with franking credits).
