    Yes, you can place more than one order at the same price. You may get questioned on it but if you can convince your broker that the orders are legitimate its ok.
    If you are the only seller or buyer at that price the ASX would expect you to put one order and not multiple orders to ensure you aren't making it look like there are lots of sellers.
