The Perfect Storm had it's soft opening on the 1st day of the 2016/2017 season (24th September) but it had it's official opening today I believe as the Illawarra Mercury has finally published an article about the world-1st ride. The article features 5 images & a video of The Perfect Storm in operation as well as an image of The Perfect Storm's logo.
But I got disappointing news - Despite soft opening on the opening day of the 2016/2017 season, like I highly suspected, construction was indeed running behind schedule (but enough to be operational). This means not only theming is uncompleted but the whole final large Tornado is still open & without special effects. I can't confirm if the 2nd small Tornado is enclosed or not yet based on the photos/videos I've seen so far. The 1st small Tornado was always intended to be open.
The Illawarra Mercury reports "...some minor cosmetic works still to be completed". If they are referring to the enclosing of the Tornadoes instead of the theming, if anything, they are not 'minor' works - they add pretty significantly to the ride experience.
So unless Jamberoo can finish construction on the weekdays it is closed on, there is a slight chance the full experience of The Perfect Storm might not be ready until December 2016. If not, April 2017 and the worst case (and I think probably most likely) scenario, September 2017.
Maybe someone who knows the construction process of enclosed Tornadoes/Tantrum Alleys better might be able to confirm how easy it is for Jamberoo to finish building The Perfect Storm?
Also, in the Illawarra Mercury's video, it mentions at the end "Even a house is in the storm's crasp" referring to the still under construction small tubes shelter. Maybe they got word from Park management that the small tubes shelters will indeed be themed to a rusted corrugated galvanised iron-roofed wooden building (with a concrete chimney) like I speculated above.
