I have a few .net.au domain names which I'm looking at setting up using Wordpress based on the domain name subject. You've got the domain name for 2 years now so you may as well look at using it for monetisation if no one wants to buy it.
Once it's an established website you may find other parties are interested in negotiating a price?
Good to hear. I have a lot of ideas for the domain content. I think the comments by some that all .net.au is worthless is way off the mark.
