I've been looking for a Gerni with the Patio Washer, and found this one on Amazon UK that actually would ship to Oz. As a bonus this one also includes a drain snake and auto wash gear.
Nilfisk brand their gear as Gerni here in Oz (http://www.nilfisk-alto.com.au/Products/PressureWashers.aspx) and from what i can gather the equivalent model is the Gerni Classic 120.2 Pad High Pressure Washer. Harvey's have it for $399, Sydney tools the same but you do get some free stuff.
