If last quarter is anything to go by then their cash and receivables should be around $30-32m AUD by June 30th, as that figure jumped by ~$8m for the March quarter.
It's possible that they pay a large dividend around 1 cent, but maybe a 0.5c div would be more prudent and then they could assess a half-yearly one (or even quarterly one if its going really well).

I note directors and management don't own that much stock so maybe they couldn't care less about dividends. Guess we'll find out!
