Remove string before the - character

Remove string before the - character

Hi,
 
I am trying to split out a string.  E.G "Australia - VIC".  I want to remove everything before the -.  The line of code I am using to do this is:
 
var
state = optionText.replace(/.* \- /, "" );
 
This works in IE7, but in all other browsers is only removing the - resulting in "Australia VIC" rather than the desired "VIC"
 
Please help!
