While Australia now subscribes (on paper) to the use of a nominal single phase
supply of 230V +10%/-2%, the reality is that the average supply voltage will be
at least 245V or higher.

Note particularly pages 31 and 32 of this 2008 document
http://www.ena.asn.au/udocs/ENA%20Cu...20Supply .pdf

and this short paragraph;

"Although the nominal voltage in Australia is 230V, the voltage range used in
Australia is very similar to the 240V ±6% range used under previous voltage
standards and regulations."

In other words, because the system previously was set at nominally 240V, no
electricity supplier is about to actually lower it to 230V.

As an example, for those in Australia who have just installed a grid-tie PV
system, the requirements specification states that the inverter output voltage
will be 240V, not 230V.
