If you asked last week, i could've sorted you out with a ticket for the melbourne show last Sat -that my mate was struggling to get rid of!
Nothing unusual... Promoters know its too much of a risk and loss in profit to bring shows with artists like Kraftwerk, Sasha, Moby (who's payrolls are fkn ridiculous as you could imagine) down to Adelaide - for a festival that doesnt have a reputation already like Parklife and FMF has. They would probably pull plenty of ticket sales no doubt, but nowhere near as much as the other capital cities
