Two helicopters collide - Gold Coast, Queensland - Sea World 2/1/2023
There is no definition of landing in the document you refer to either https://www.legislation.gov.au/Detai.../Html/Volume_5
We all know what we mean by landing but that is not the same as approaching to land and is very different for helicopters when compared to fixed wing.
While it is understandable that some victim initially didn't want to release her cell phone video out of consideration for people affected by this accident (everything is understandable when it comes to human emotions, including crimes of passion), there clearly is a strong public interest (I mean this in the legal sense of the term) to get access to each and every passengers' snaps and video recordings. (I bet all eleven of them like it is common practise today were recording during this pleasure flight.) It would be wrong for the investigators to suppress this information.
In particular I would be interested to to see the video that this surviving passenger took on his tablet computer....

I see KRviator has responded from recent experience, but see also post #80 by Avv and post #280 where I copied some material shared by 'Speed Bird' on YouTube regarding the apparent usage over recent years of the various Sea World helipads. The discussions here so far have tended to focus on the Sea World facilities, but it is worth realising that Gold Coast Helitours has three helipads (and small hangar) at the end of a jetty off Marina Mirage not that far south of Sea World. Years back, there was also an operation called Happy Wave (based on logos on side of their Squirrel) that operated off a floating helipad on the Broadwater in generally the same area. I also remember a Hughes 500 was operating joy flights out of a paddock either to the north or south of Sea World back then, so the area has been busy with various joy flight operators from various locations all in reasonably close proximity for many years now. As far as I know, all those operations had remained accident free except for the loss of Long Ranger VH-TCH and all its occupants, which had been a single aircraft accident rather than a collision.
I’m simply curious to know what was different in this incident (procedurally) that both pilots weren’t expecting to see another aircraft?
- What radio calls are generally made when lifting from the pad or inbound to the pad? Even if it’s localism’s
The question who had right of way it irrelevant in this case. By definition, those rules only applies to two aircraft that are aware of each other. The Rules of the Air then prescribe what evasive manoeuvre each aircraft has to make to deconflict. (Like it would be stupid if two aircraft on a collision course would both pull-up, and then still collide despite both pilots having taken evasive action.)
The principle of VFR is "look & avoid", not "look & be righteous". If I was the only aircraft that sees the other (and the other aircraft seems blissfully unaware), my only duty is to avoid. If both aircraft were unaware of each other, it is irrelevant who would have had right of way.

Interesting that the ATSB say it will take 18 months for a report but it seems they were pretty quick to hand footage to the media, footage they weren't authorised to pass on. It seems disappointing, correct me if I'm wrong.
I'm not convinced that that is the climbing helicopter that's circled. If you watch the video on Youtube at 25% speed, the white structure looks to be in front of the rear of whatever that dark object is, (truncating the tail boom to look more like a Jetranger than an EC130). The EC has substantial rear skid struts that aren't obvious in the video. I think it is some feature on the ground. The rotor effect is the Channel 7 text scrolling across that feature.
Images below are the departure helipad seen either from video footage taken from a Sea World joy flight some time back (posted on YouTube) or from the '3D' view on the Apple map app (from roughly the same perspective as it was seen from -XH9). The latter is also based on material from several years back. There is no obvious larger white structure near the helipad, though I guess it could easily be a white marquee set up at any time.

As a fixed-wing pilot I know zip about choppers, but the same principles apply?
Enhanced Video Still Images 2
Further to my post #283 above I have done a bit more work.
1) I have posted my enhanced video here:
https://imgur.com/KgPtBIN
https://imgur.com/KgPtBIN
I hope that anyone interested can see it. It is at zoom 2X, and Speed 25%, with contrast and saturation increased in a Box around the apparent 2nd Helicopter. In real time, if this video starts at time 0sec, then the rear passenger's shoulder tap would be at 12secs, and the impact would be at 13.5 secs.
2} If anyone has a source for the full "Inside The Helicopter" video without the Channel7 News logo on it, please let us know! The Logo is a major factor in making the video difficult to see in the area of the 2nd helicopter.
3) I withdraw my suggestion that you may be able to see the 2nd helicopter blades flickering slightly. It is probably just the News Logo!
4) But I maintain that it is clear that "Mystery Object" is above and in front of the ground, and is moving left-to-right, which is correct for this to be the 2nd helicopter, to my understanding. It may even be judged to be climbing. And it is generally in the correct position for where the rear seat passenger excitedly points later on.
5) you see the "2nd Helicopter" approaching a building with dark grey walls and a white roof. This building is clearly seen, in the correct relative position, in this Photo of Take-off Helipads cropped from Helispotter Post #58.

6) I also post this drawing of the EC130 helicopter, for comparison.

I hope some of you find this input informative,

I only pointed out the right of way issue because someone somewhere will want to blame someone for the accident and the surviving pilot did technically have right of way.
This post is mainly intended for Ivor_Bigunn (#309) and DroneDog (#310). Good work on your continued effort to enhance what is seen in the video. Using a still from clip prepared by Ivor_Bigunn, I have marked up an attempt to reconcile what we see against an approximate outline of the orientation that -XKQ may have had relative to -XH9. What seems especially hard to reconcile is the distinct white mark(s) on what should be the helicopter fuselage. As far as I can tell, -XKQ was mostly dark grey just as -XH9 is but would also have had light coloured 'Sea World' logos on the engine cowling. Any better interpretation?

Update:
The 'unexplained white' might be reflection of the starboard side pop-out float cover off the gloss fuselage paint (see my post #321). The light coloured float covers might also explain why the starboard side skid isn't more obvious and shows up as a blurred light grey immediately above the walkway to the helipad.
In any case Channel 9 has now also made that on-board footage available without the watermarks all over it, and -XKQ can be seen much more clearly, including rotor turning:
Also in this clip, it confirms there is a white structure now located immediately behind the departure helipad, see screen shots below:


Update 2: For a quite different but more credible interpretation of view of -XKQ from -XH9, see subsequent post #373 by Traffic_Is_Er_Was. But I have otherwise left my post here as it originally was.

Sadly, the other Pilot shall not have that opportunity.
Hopefully there shall be enough evidence gathered from Audio Tape Recordings, Individual testimony, witness accounts, video, and forensic examination of the two aircraft to determine what happened with some reliability.
The Investigation shall piece together an account using all of hat information and then consider how it all came to happen then make some suggestions on how to prevent another similar tragedy at Sea World and other similar operations.
Hopefully, that is the case as there should be some good come out of this sad event.
If this is true, or if the media obtained the obtained the video under any nefarious circumstance, I trust they will be hung out to dry.
Don't be so sure that is what happened. In the commentary with the footage at the following link, the 7 News presenter says: "..been obtained exclusively by 7 News... the vision obviously will be passed on to the experts investigating this tragedy". So sounds to me like 7 managed to get hold of the material first, then planned to pass to ATSB. I can well imagine media people managed to make it over to the crash site long before any ATSB personnel, or perhaps even police, arrived on the scene. Passenger may have handed over material under a false impression they were giving it to an official investigator. You can bet this will be investigated as well now.
Realistically the ATSB already know what happened. Two modern helicopters collided on a clear day conducting joyflights. Its the why that will be the focus of the investigation particularly why a helipad with a white cross on it was being used. The fact that the CP was flying from that helipad would be significant as he would be the only pilot within the organisation that could authorise its use. The focus will be on the whole organisation ,including Sea World management, and its contribution to the accident. The surviving pilot was unfortunately the last line of defense but if he wasn't told that the old helipad was being used then why would he look in that direction.
To all those who shout " He should have had a better scan" or " He was looking in the wrong spot" consider this. How many of you look behind when proceeding at a stop or give way sign?

AustAirData explains that VH-XKQ (c/n: 4639) was previously registered PK-URR. At following link, there are several photos that are probably of it from February 2019 heading north along Queensland coast, possibly on its way to Indonesia?:

While there is another photo of PK-URR on the Twitter page of Said Oemar, which does have light bands on its fuselage, that may well be another helicopter (c/n: 4060):
