@Klutchif information of FY is available, why you even bother to compared the HY ones, I believe in the investor call session after 1HY19, the CFO did mention was a big Dec order pull up the 1HY19 result.
I think some of the holders might have caught rich kids issue, they want not only their company to make money, but also from the section they expected. so winfall here and there dont count ...
imo, the announcement says, SDI returns on equity about 7.5% (3 times quicker than Australia economy), returns on assets over double digits, they are going to pay 2.5c div fully franked (that's 3.7% return on sp of the day, 3 times higher than RBA rates or bank deposit rates)
next FY, once Brazil warehouse fully functioned, they will save another 2 or 3% on freight from current capex investment.
