Think there is a bit of media hysteria. When you have a fuel smell (along with the 'reported' possible indication of excessive fuel usage), emergency services would be on hand. Seen many flights divert to Wagga for many reasons but today must be a very slow news day.
Will be interesting to get the summary of the facts from the ATSB.
