I had a few down here in Melbourne. One was so tough I couldn't grab it with gloves on - had to squish it (only got it second time I saw it). Have installed a Beetle trap from a guy in Sydney (Not sure if we can put names so Google 'Small Hive Beetle Trap sm'). Best few $4.50 I have spent (and he posted it to me the next day) - it hangs between the frames and you put some veg oil in it - the bees chase the beetles who run in to hide, and well ... it is a bit too oily for the beetles to get out. I have caught a few more in the trap and haven't seen one loose on an inspection since.
I read a paper that said they must pupate in the soil and will do so within 1m of the hive, so if you can put them on tiles or concrete for a while it may reduce them a bit. However, they can fly a long way and the lavae can crawl a long way if they have to, so it isn't a cure, but sure makes life a lot harder for them, esp if you have ants or birds around to eat them on their journey. I have mine on a tiled surface where they will stay till the beetles are long gone.
