There was actually an announcement from the QLD government in the last two days with these statements from the chief health officer:

“Globally, we are seeing a concerning deterioration in the mental health and wellbeing of young people – and we are taking action to combat this in many ways.

“The increase in self-harm events observed among young Australians since about 2008 looks just like a new virus epidemic. This period coincides with the introduction of smart phones and social media apps.

“We believe there is growing evidence that the health and wellbeing of young Queenslanders is being harmed by unrestricted access to social media, and it requires a public health response.

“There are benefits to social media including social connection for those who may be isolated – but it’s important there is a balance. Children under 14 years may not be equipped with the emotional maturity to deal with its complexity.

“Parents of older teenagers should also remain active in understanding and guiding the amount of time their children spend on screens, including for social media activities.

“As the state’s leading public health body, Queensland Health has a duty to inform the Queensland public of our position and concerns around unrestricted social media use in children and its effect on mental health and wellbeing.

“It’s time for Queenslanders – both adults and children – to start a conversation about this important issue.”

The announcements from the premier look promising as well (even if we are heading into an election), though I believe SA might've been the first state to start talking about it.
