Here's the thing. Whether or not there are 'restrictions' in place, the QLD Gov and the CHO have stressed the need for people to distance, change behaviours etc. Most dining facilities are still operating at reduced capacities to maintain distancing, and most businesses are still operating under the terms of their covid-safe plan.
If the park factored in zero-contact interactions with characters in their plan, then, until they revise a new plan and publish it, they'll follow what they've already got. You can't sanitise plush fabric gloves easily in a manner that won't wreck the suit or cause it to be sopping wet... so you just don't have contact. Disney parks in Florida still distance their character appearances with physical barriers to keep guests away from them - and they've pretty much reopened everything - even mask rules are dropping in public areas.
Many of the Covid-safe plans out there are being relaxed, provided folks who enter the facility are using the QR code, but there are still too many people who enter shops and restaurants without using them, and it shouldn't need to be policed at this point.
The biggest problem we have right now is that as soon as we lift a restriction, or change it from 'mandatory' to 'recommended', the great unwashed use it as an excuse to say 'I don't HAVE to, so I WONT'. Apparently "you're allowed to exercise" translates to "people are allowed to sunbake on the beaches!"
I saw a woman on Facebook this other day talking about how the QR system wasn't mandatory until July 9, telling everyone they didn't have to use it (Whilst failing to understand the QR system was mandatory for businesses to use by July 9, but that it should still be used by every business that already had it. In one sentence she talked about how she thought it was important to use it, but how proud she was that she told off some lowly coles employee and walked in anyway because it wasn't 'legal' yet.)
...and I would never have thought it would be such a hard concept to grasp, but I learned otherwise 15 months ago when we had to have celebrities on youtube showing us how to wash our hands properly.
Just because the government says 'no restrictions' - that doesn't mean we should just go back to completely normal. All it takes is for one person to become complacent at the wrong time and we're all back where we started.
