If you mean shutting down entire suburbs, definitely not in the foreseeable future. For the same reasons the ABC keeps breaking the law requiring them to provide transcripts and/or captions for media published online. They have forgotten, or worse, they are ignoring people with disabilities exist and should be part of the conversation.
I have zero objection to single streets being shut down to have community festivals/events, but in a world where many many people struggle with mobility, there needs to be some form of semi-direct access.
Or we at least need lots more public seating of differing types/heights, public toilets that aren't fucking rented port-a-loos, group tables that have space for wheelchairs, locking stations for mobility equipment that aren't just for pushbikes and that aren't placed haphazardly in the way of foot traffic on the skinny broken footpath, etc. You know, infrastructure and shit.
Also, be better, ABC. Cheap automated transcription tools exist, and it doesn't take many people to check for accuracy and add it to the media player and page. You're literally legally obligated to do this. There are even businesses you can hire to do that with turnarounds in under an hour. For fuck's sake, the royal commission report just came out about this sort of shit.
