Here's my thoughts. Just because many are negative doesn't mean it's a bad site, I like the look of the site just a few improvements can be made:
1. The "joes.com.au - Domain name sales" header appears stretched and fuzzy (I much prefer your logo in your DP)
2. The picture of you (I presume) does not seem to fit. Maybe have it on the about page instead
3. On the resources page you have the a tag covering the spaces as well (probably just a typo)
4. I like that you've separated the .net.au and the .com.au domains though it may be a better idea to have the better domains (.com.au) on the left
5. I'm a bit confused about the RSS link as it's not for the domain names (at least currently)
6. This is personal preference but maybe use a sans-serif font to look more modern etc + my personal preference is that they're heaps easier to read and look better.
I do like the look of the site even though I've come up with 6 things to change
