Looking at a lot of the social media posts associated with this event and the comments from potential attendees reasons for not attending: the lack of the F/A-18s certainly made some potential attendees decide not to attend; the late-ish withdrawal of the FW-190 (for the second time) made some potential attendees decide not to attend, nothing new and significant attending this year's show (eg if HARS had gotten the Tracker cleared to fly and/or the RAAF provided a Super Hornet that would have drawn quite a few people) made some potential attendees decide not to attend, AND last but not least, the unpredictability of the weather over the weekend. Particularly a number of people I know who would have ventured to the airshow on the Sunday as an 'opportunity' type attendance, didn't because the weather predictions for the day were so unfavourable. As one person I know who was thinking of going with a couple of mates noted, you only had to look at the BUMET rain radar for Wollongong on the Sunday morning when you got up to see the big bands of rain approaching from the south and go "Nah!!". As it was the weather did play a big part in the weekend's events and outcome.
I hope they can keep it going, but if they don't have the big drawcard aircraft and keep the flying program 'fresh' then they will struggle to draw people to the event as an annual event. Maybe they need to look at running it as an event every second year, the 'other year' to Warbirds Down Under at Temora.
