Note that this is a dessicant dehumidifier, so it works by heating up silica gel beads, meaning it will often heat up your room significantly (and draw quite a lot of power in the process). I would only suggest getting this if you live in a colder region; you can still use it in a hot climate of course, but it'll make your room uncomfortably warm and you'll get a bigger electricity bill than if you used a compressor dehumidifier which works best in warm weather.
According to Ausclimate themselves, the efficiency cross-over point is approximately 20°C, so if your home is usually above that temperature, you're probably better off getting a traditional compressor dehumidifier instead:

If you do end up shopping for a compressor dehumidifier, get the most powerful model you can afford — I suggest looking for a moisture extraction rating of at least 35L per day, as that maximises energy efficiency and thus saves you money in the long run when it comes to your electricity bill:

Great price and decent dehumidifier. I paid $350 a few months ago (when there was a dehumidifier shortage in Sydney) and thought that was a good deal.
