I have had the domain aussielook.com for a few years and have a site up which ranks very high for a lot of related search. I have been in the process of a complete re-design of the site and are about to launch in January 2012. I have changed the focus of the site to not only generate income from affiliate marketing but also to sell advertisement space to local business. I have registered the domain aussielook.com.au in order to do this. My plan is to pull down the old site when ready called aussielook.com and put up the new site aussielook.com.au. This is where the question comes in. I plan to put the site aussielook.com.au on the domain aussielook.com and have a simple one page re-direct on the domian aussielook.com.au to the site. I hope this makes sense. Will google frown upon this and is it bad practice. My reason for doing this is that the original domain is well established and parts of the site will be much the same just the name change to aussielook.com.au to appeal to locals.
Thanks in Advance
