I had the same problem. Are all the drivers loaded? On the LG update tool are the words "Install USB Driver" ]It does not look like a button but it is. Click this Let it do its thing, downloading....it will go through about 3 or 4 steps.OPening rar files.... When its is finished reboot PC. And connect phone again, and it should show new update available, to be safe I changed my country to NZ, but I am sure Australia version is the same. Good Luck.
