We will end our live coverage of the verdict here, on a very difficult day for the parents and friends of those who died and were injured on that day in 2021.

RIP Chace Harrison, Jalailah Jayne-Maree Jones, Zane Mellor, Addison Stewart, Jye Sheehan and Peter Dodt.

And all the very best to the first responders so affected by that horrible event.

Andrew Dodt, father of Peter Dodt, one of the children who died, has issued the following statement:

"I've been broken for a long time, and I think I'm going to be broken for a lot more.

"I thank you for walking the path with us, it was a very long path and I think we've still got a long way to go.

"Our hopes are just shattered now, at the end of the day all I wanted was an apology for my son not coming home, and I'm never going to get it, and that kills me."

Before today, the victims' families indicated they plan to return to court, with a coronial inquest set to begin at a date yet to be set.

The families also launched a civil class action against the state of Tasmania and Ms Gamble in December last year, on the third anniversary of the tragedy.

Even if Magistrate Robert Webster had found Ms Gamble guilty, he could not have sentenced her to a prison term.

The maximum penalty for a category two offence under the Work Health and Safety Act is a $1.5 million fine for a corporation, and a $300,000 fine for an individual conducting a business.

The judge found the evidence presented during the case did not support the proposition Ms Gamble was ever supplied with a manual which contained illustrations of how pegs should be inserted into the ground. 

From the decision:

"There is no evidence that a different peg installation would have made any difference. In any event the evidence with respect to the four pegs which were installed is they were installed correctly; i.e. at closer to 90 degrees rather than 45 degrees."

My ABC colleague Sandy Powell, who has followed this case, explains seven children were inside the castle when it was thrown across the oval, and five of them did not survive their resulting injuries.

Another child was waiting in line and died after being struck in the head by the airborne jumping castle blower.

The charge had alleged Ms Gamble failed to comply with her duty "in a way that exposed the children to a risk of death or serious injury".

Magistrate Webster said the jumping castle becoming airborne on the day was "more likely the failure of the anchorage system in the manner suggested by (defence expert witness) Professor Eager".

"In those circumstances the failures to comply with the duty, which I have identified, would not have prevented the failure of the anchorage system." 

He said Ms Gamble "could have done more or taken further steps, however given the effects of the unforeseen and unforeseeable dust devil, had she done so, that would sadly have made no difference to the ultimate outcome".

The operator of the jumping castle, Rosemary Gamble, has released the following statement:

I want to say that I accept how deeply and tragically this incident impacted so many people and families

I realise those scars will remain for an extremely long time, likely forever

There are no words to describe how I have felt ever since that tragic incident took so much away from so many people and left nothing but heartbreak and emptiness in its place

I am a mother. I can only imagine the pain that other parents are living with each and every day because of this terrible thing that happened. Their loss is something I will carry with me for the rest of my life

Every moment that goes by I wish this tragedy never occurred, and that the families that were torn apart were still whole. There is not a moment that goes by where I don't feel so terrible and painfully sorry to every single one of those people who were impacted, and continue to grieve for their loved ones

I don't ask for people's understanding. I accept that people will feel anger and animosity toward me. I know there is nothing I can ever do which will change that

I never meant for something like this to happen. And I am just so sorry that it did.

We understand the jumping castle operator Rosemary Gamble will be making a statement available shortly.

Obviously the families of the deceased children are very distressed at this time.

If they come forward, we will bring their reactions to you.

Magistrate Webster wrote that the incident may have been unavoidable.

"Ms Gamble could have done more or taken further steps however given the effects of the unforeseen and unforeseeable dust devil, had she done so, that would sadly have made no difference to the ultimate outcome," he wrote.

From the judge's decision:

This tragic incident occurred, on the evidence, due to an unprecedented weather system, namely a dust devil. The dust devil was impossible to predict. 

As the DPP properly conceded the dust devil was unforeseen and unforeseeable. I am satisfied Ms Gamble had a health and safety duty under s32(a) of the Act and in some respects she failed to comply with that duty under s32(b).

However I am not satisfied ... those failures were a substantial or significant cause of the children being exposed to the risk of serious injury or death. 

This is because I am not satisfied beyond reasonable doubt the failure of the anchorage system occurred in the manner suggested by (the prosecution).
