This may not exactly fit the context of this site, but I think its worth a shot, and the answer may be useful within the context of the site.

I am attempting to call the Australian phone number listed as 131542 on the Kia of Australia Contact Us page from my US based mobile phone. Though, even after reading the Wikipedia page on Telephone Numbers in Australia I can not seem to get it correct. My best guess is to use the "International Access" code of 1100 along with the country code 61 prepended (totaling 61-1100-1315421). Though I've had no luck with that or any other seemingly esoteric collection of codes and the listed number.

How can I dial a 6 digit Australian phone number from a US based mobile phone?

This may be useful to other travelers trying to contact Australian companies, hotels, etc. And for those interested, Kia of Australia sells a cargo roof rack for my car that Kia of America does not recognize or sell. I am trying to get more information on it.
