If this can happen to an organisation ,on the surface well run and well managed and considered as just plain bad luck, then the only way to avoid such things in the future is to stop all scenic flights out of Sea World.
I'm not saying that's the case here - there may well be important changes needed, and of course it's loss of human lives we're talking about, with all the terrible ramifications of that. My point is that safety systems should certainly have robust examination and ongoing improvement built in, but I believe there's a tendency for organisations, and outsiders, to conclude that 'something' must be done for the safety system to have done its job. The conclusion that no changes are necessary, even if it's supported by the investigation, often doesn't fly for those seeking answers.
That can be a good thing, if it roots out bad practices, but can also lead to institution of counter-productive (in the safety sense) measures, and in some cases, a smoke-screen warm and fuzzy feeling that 'we did something, so now we can forget about it.'
Edited to add: 'we did something' is also too often translated into 'we were seen to do something.'

I don't know about the relationship between Sea World Helicopters and Sea World theme park but the Dreamworld fatal accident (non-aviation) may provide an insight into how these parks operate and are managed. Once again it just leads me to think that organisational issues will be at the centre of this accident. The bolding is mine:
The Queensland Coroner, James McDougall, released a report on 24 February 2020 detailing "irresponsible", "dangerous" and "inadequate" safety practices at the theme park that contributed to the four deaths, while recommending the Queensland office of industrial relations consider a prosecution. The ride had endured frequent breakdowns in the days leading up to the accident, and had several design and construction issues which contributed.[28]
Mr McDougall told a Brisbane court Dreamworld had a reputation as a "modern, world-class theme park" yet its safety and maintenance systems were "rudimentary at best".[29]
and that: he would refer Dreamworld's parent company, Ardent Leisure, to the Queensland Office of Industrial Relations. He said Ardent Leisure "may have committed an offence under workplace laws".[29]

Lookleft,
In a conversation with a CEO of a large US Based Part 135 Operator who was expounding about how safety conscious his operation was and the very high emphasis it placed upon safety....I let him finish and then asked him what it felt like to be the CEO of a business that had never gone a year without a fatal accident and what did he think when he looked at his Pilots did he ever think about which one was next to die in his employ. To his credit he admitted he was troubled by that sad fact and tried to understand why that sadfactnwas so.....and I believe he was sincere. His background as a helicopter pilot included a serious accident of his own due to a catastrophic failure of an aircraft.
Your point about an Operator's Safety Case is very true....unless the Management is sincerely dedicated and willing and able to spend the money and corporate assets that wonderful Safety Management System that is found in the Files requires.....there is no Safety Program but rather a false facade that looks like one.
The best example of that concept was the City of New Orleans Emergency Management Plan that failed so disastrously when Hurricane Katrina hit in 2005.
On paper the plan looked great.....the School Bus fleet would be used to evacuate residents ahead. of the Hurricane.....only one Bus was used and it was stolen by a Citizen who used it to do just that.
People coming to the Convention Center would bring three days supply of food, medicines, bedding, and water......that did not happen.
Of course....the City water system failed.....with all that meant to the Thousands of people stranded at the Convention Center and all through the City.

The Wikipedia description of the Pan Am / KLM 747 take-off collision ( https://en.wikipedia.org/wiki/Tenerife_airport_disaster ) mentions, under the sub-heading "Communication misunderstandings", about simultaneous radio calls causing mutual interference on the radio frequency, which was audible in the KLM cockpit as a three-second-long shrill sound (or hererodyne). Not saying this is the case here, but how is this sort of 'over-transmission' issue managed now? Do the pilots who transmitted become aware their messages have become scrambled?
Well I did in #303, but in the context of the otherwise accident free operations in that location over many years. I think it was also mentioned by others in one of the first 20 posts which I can't currently access, and of course it also got a mention in #386...

If (or when) there is a collision it won't be bad luck, it will have been inevitable.

Aviation VHF is normally AM Simplex.
While this may not have been a contributing factor to this incident, it happens so often worldwide that it is a wonder it hasn't been a significant contributor to a number of other near-misses (what a misnomer) or scenes of confusion. Certainly listening to 10 minutes on LiveATC on a busy time will confirm that.
When I stood at the gate at SeaWorld next to the pontoon and watched the helicopter take off and land at short intervals through the wire fence, the thought passed through my mind wondering what could happen if the were multiple aircraft. That was ten years ago, and this incident triggered that memory vividly. Maybe the number of aircraft may have changed due to demand, however the procedures may not have been adjusted to cope. I'm certain this will be one area that investigators will closely scrutinise.
I would be sorry to see the baby thrown out with the bathwater. The location, right at the waters edge next to SeaWorld was the main attraction for spur-of-the-moment short joy flights for tourists, and even the bystanders were impressed by the noise and backwash of a real helicopter so close by. To shut these down completely would be a sorry result.

As usual...when a discussion gets to this point where we discuss Risk, Probability, Chance, Luck, and even Fate......I suggest folks read "Fate Is The Hunter" by Ernest Gann.
Despite his writing about his experiences prior to and during WWII flying Transport Airplanes, his is an insight and wisdom that still applies today.
I wish I had a Leather bound copy of that Tome as it would be right next to some other books I gain inspiration and wisdom from when reading from them.
Short version is there are risks, real risks, imagined risks, reasonable risks, un-necessary risks, and un-acceptable risks in aviation.
The trick is to figure out what they are and which one you are dealing with at the time.
There is always risk....how we deal with them is important but identifying them is the key.
One short quote from him is "In this game we play for keeps!".

I have operated over the area of the search for O’Conner and know where the lake is. 54 20 N 73 30 W.
On a ferry trip to Brazil a few years ago I visited a lot of the airports he mentions in the book.
Also my Uncle was an officer on. the ocean liner Lurline for the Matson Shipping Line which tried and failed to start the airline he worked for post WW2.

I’d imagine the operation in question were at best, advising of their movements. EG “Chopper 1 lifting for a scenic to the south” (Which, I would have thought would have had the inbound pilot looking out “very hard” - lots of head movement to clear the blind spot for eg - not evident in the video. So perhaps there was an issue with this. Potentially the lifting call was “stepped on”.)

Just before he straightens up he is looking directly in front of the A pillar where the departing helo would roughly be, it's hard to tell from the video but his lips seem to move just after that, I think he makes a call.
I speculate that he did sight the departing aircraft, assumed he'd been sighted and that the departing helo would give way, continues with his descent and calls to confirm.

The part where they are listenening as another crew loses all it's alternates on a pre-war winter night is sobering stuff.
A preview indicated 60 Minutes on Channel 9 this Sunday will have an interview with some of the passengers from VH-XH9. Clip also on YouTube:
