Yes the more the mainstream media (television and newspapers) pickup these large domain selling stories, the better the .au marketplace will become. If the auDA relax laws in regards to having an ABN/ACN then it would also open up to international traders and push prices higher.
auDA have closed any applications to become a .au registrar until further notice, but i hope they do open it up to create more competition. The wholesale pricing for domain registration may also be lowered as more demand for domains occurs.
Enetica look to be the best value for ownership transfers, they may be doing this to get owners to transfer their domains to their service, would sure net them a lot more business being so cheap to transfer. Planet Domains charge $110 for a transfer of ownership too, i have heard others to be around the $200 mark, quite ridiculous if you ask me.
