Ann: Corporate Presentation, page-46

Once the 10c support was breached, there seemed to be a drop-off in buying support and a concomitant increase in holders being prepared to sell for whatever price was being bid. This eventually resulted in 9.3c being hit. ASX closed at 9.5 and chi-x at 9.6c

The drop is not surprising though given the steep SP rise.

The sales above 10c have been either matched trades at 10.25 or 10.5.

As can be seen here, all offers above 10c are either in full cents or half cents. Is this because it's regulated? ie no smaller fraction?
