I thought I'd go to 2K Games site and ask them about the availability of DLC for steam users in Australia & New Zealand. So I go to the site, choose Australia as my country, click on Support, scroll down to Contact Us and click the link - and get "Unable to Connect". looking at the link it's trying to direct me to:
Selecting UK as my country I at least get an email address for Europe. Guess I'll just email both the Europe and US addresses as I can't find any way to fix the above link to get a valid page to display.
If I get a response back I'll post it.
