It's a good question... I just don't know, as I don't really have any serious experience developing .net.au's. I would have thought not, but a couple of people who really seem to know their stuff swear that they are much harder to rank.
Only way to know for sure is it to give it a shot yourself. Make sure you keep us posted!
Interesting data on the .net.au! Could this be explained by other factors like the quality of the backlinks or the age of the domain?
I'd like someone to show me a thin .net.au site that ranks well for it's exact match term.
Hard to judge as it depends on numerous factors. I've got a very basic site at Hunter Valley Accommodation .net.au. I've put very little effort and time in. Keeping in mind that it's a very competitive term, it ranks front page on Bing but nothing on Google. From my experience Bing doesn't care but Google does.
This (huntervalleyaccommodation.com) parked domain ranks #35 for "hunter valley accommodation" and your 20 page, 2 year old site with 140+ links is nowhere to be seen.
Ummmmm, I think that's what I said
I personally doubt a keyword.net.au vs keyword.com.au domain would be worser off because of the extension. But that is just an educated guess.
I was just backing up your point Troy.
I thought the same but am now having doubts.
I think over time the net.au may suffer due to experiencing lower click through rate. All things being equal, human nature may mean a searcher is more likely to click on a com.au. Google definitely take CTR into account.
Also Google may assume that if someone uses the net.au they weren't first in. Would it be fair for Google to apply a +ve weighting to the first person to register keyword.ext ? You could argue a case for that, I guess.
Can't see any other reason why Google would discriminate.
