...........i see in the us you can purchase shares bit by bit with direct debits weekly / monthly for small amounts directly from the company..........
I know what you mean. At one stage, CSR did allow its shareholders to regularly buy shares directly from the company without going through a broker. I don't believe than any company listed on the ASX allows that now.
However, there are now other avenues which maybe offered by companies form time to time if they wish to raise cash.
The first being a Share Purchase Plan under which a shareholder may purchase up to $15,000 of shares in the company. Milton (MLT) has one on the go now but unless you were a shareholder
before the SPP was announced you cannot participate.
The second is an entitlement offer where the company may make an offer to its shareholders to buy additional shares at a specific price and in a ratio according to the number of shares held. For example, BKI has such an offer and shareholders can buy one additional share for every 15 held at $1.48 per share.
Third is the option avenue where shareholders can issued with no cost options to buy shares in the company at a specific price but the option has an expiry date. An example is WAM which appears to do this on a semi-regular basis in order to raise more capital. You can purchase the options on the market for a trade or you can purchase them with a view of actually taking up the option to buy.
There are a couple of other methods such as Bonus Share Plans, ie exchanging dividends for these which normally attract no franking credits - it's a Capital Gains play but also useful for overseas shareholders who do not get the benefit, either in full or in part, of franking credits.
And then there is the DRP which you mentioned.
