I can't speak for what exactly they do in Australia. I do use mopani driftwood in my tank, and can tell you that it's extremely dense. It doesn't float in water. My pieces are large and required several months of soaking in water, using hot water, or salt in the water, or bleach in the water, changing the water every few days. This was to get the tannins out. I'd think that after all that, any residue from fumigation would be removed.
Smaller pieces don't take as long to process, but I suspect you'll still need at least several soakings of the wood. I doubt you'd have a problem after all that.
