reversing a 301 from .net to .com.au - for better google.com.au rankings

[nippi]

Some years ago, my client wanted international traffic more than local, owned to domains one a .net, one a .com.au.

She was running the site under the .com.au version, so we changed to the .net version and 301ed the whole site to the .net url.

Worked fine for a while, but reality is people don;t buy from the site except from australia anyway.

Site ranks near the top, but not AT the top in australia.

The site has inbound links both to the com.au and .net versions, but more to the ,net version.

I am wondering if my client stand to benefit from instead running the site from the .com.au domain name, and reversing the 301 from the .net domaain name?

Likely to increase rankings?
Likely to do nothing?

Anyone got some hand one experience with this exact example?

I've had people approach me with a similar situation where they reversed a 301 direction to use the cctld instead of the generic. They came to me because they lost rankings.

This was a couple years ago, and Google has been making a lot of country-related changes in 2010 and this year, so YMMV.
