Reasonably common in Melbourne - esp where there is only a small front yard. If you wish to make a statement at the auction, drive up in a (rented) expensive car while the auction is in progress, come to a halt immediately in front of the auctioneer and bid from the car....
This is quite common in older inner city Melbourne suburbs with narrow roads and big crowds. I don't think the crowd would have been able to fit in that small front yard. Looks like an Edwardian style house which is about 6-8m wide x 5m deep.
