Agree the $1 doesn't include the time spent identifying and reg-ing them (but I have plenty of .com.au's that wouldn't pass that qualification). It would be hard work to flip most net.au for profit - even at $1.
Having said that, I didn't reg them to flip them and I wasn't blindly mining. The dozen or so I reg'd were in a specific niche and I selected them using a formula.
I should have the first site online this week. While I won't say the site or the niche (because @Snoopy might reg the remaining .net.au's
), I'll report back in a few weeks if it generated any $$$.
