VicLink.com.au was the domain name of the old Victorian Government public transport website which for the last couple of years had redirected to ptv.vic.gov.au.
Sold with a PR of 7.
The Department should have renewed it. Maybe because it was a redirected domain name there was no urgency associated with a website going down when the domain name expired so it just slipped away.
Probably similar to, though not as serious as, what most likely happened to wollongong.com.au which redirected to wollongong.com as the main website and email address so when the au expired the website functioned as usual so nobody realised there was something wrong and the au went through to the drop.
