please help! where in Vic should I buy a lot?

a general question for the pros:

I have some spare cash, approximately AUD$60K,
and am considering buying a 600m2+ building allotment
somewhere in Victoria. I do not plan to build on the land,
just hold it for approximately twenty years and then sell it.

I realise that there are possibly better ways to invest my money,
but I am looking for a simple low maintenance real estate investment scenario to dispose of some cash, which would result in a land title in my name. I am not interested in using this capital to
borrow more money from a bank.

I am Melbourne born, but live overseas, so do
not have any time to property hunt in Victoria.

I have seen 600m2+ lots of sale in places like Portland, Victoria.

Would this be a decent place to buy, with a low risk of
the property value dropping significantly ?

I realise Victoria is a big state, but what other
towns should I be considering for a low risk purchase
in the $60K range ?

Or should I be considering another state like
Queensland or Tasmania ?

Or am I a complete gallah and should not even be considering
an investment of this type. [blink]

any advise or suggestions much appreciated [thumbsupanim]
Martin.
