Pearler of a domain just the extension lets it down somewhat. Does seem that .net.au's are struggling in these early days.
In answer to the 2nd part of the question - to get the most value develop. Take advantage of the natural edge you'll get in SERP's for lingerie related searches & try & develop a bit of traffic. Start by earning rev through ads, then if things go gangbusters look to partner with an actual lingerie provider.
Always advertise in meantine though - you never know when a top paying buyer might come along.
hubba hubba ...... great name welcome to the forum , agree with all the above , i feel the .net .au's will only grow over time good luck , value i dont know ???????
Totally agree with David from NetFleet. As a standalone domain, I'd say your looking at $500 or under selling to domainers. As an online shop with decent google ranking you could ask for and probably get much more.
Competition for the term in Google's top 10 isn't that strong.
