"In early October, a potential bidder for a two-bedroom unit at Cathedral Place in Brisbane's Fortitude Valley requested to use Skype from Sydney to see the auction room and observe the atmosphere. The bidder, who had previously inspected the property, ended up buying the apartment under the hammer for $437,000.
While it was a first for Ray White's New Farm office, other agents have been using the web-based PTY Property, which provides an online bidding service that has also racked up recent sales including one of more than $3 million."

I guess this is better than phone bidding -- at least you can try to see if there are any dummy bids and see how many people are actually at the auction.
