What I care about is the lack of amenities and options for independent hikers. You can only hike the trail one way and you can only hike the whole trail, you can't hike in stay one night and hike out.
The answer seems to be; because they say so.
The trailhead and first 6km traverse private land, and the agreement with the property owners is for the public to enter, not exit, through their property.

The O'Reillys have done this for years with their guided one day Stinson walk; one of the conditions is that you book accommodation with them (not a campsite) before and after the walk. If you don't want to do that then you're free to walk it yourself and organize your own bus transfer. Are the three campsites on the Turner land or in the national park? I couldn't work it out from the websites.
dalehikes, as you know, I agreed with you two pages ago and I agree with you now. I'm a member of NPAQ, sent them feedback as requested and supported their final submission. Unfortunately, that horse has bolted. The legislation has been lawfully amended and the approvals given. I believe other Scenic Rim tourism operators are interested in the outcome and have their own proposals to make, so that's the way it is. If someone submits plans for a water slide down Springbrook it will have to be opposed at the community level, because the legislation is as it stands and Joint Ventures are the new normal. Similar things have recently happened in Tasmania and New Zealand, with similar opposition that was similarly overruled. As Ned Kelly said, such is life.
I would much prefer to see the government manage their own national park developments than get involved in joint ventures, but there isn't a brass razoo in the state budget for that sort of thing at the moment. They only had about three brass razoos before the current debacle, and all three will have gone towards keeping the hospitals open and the lights on

. Additionally, TMR have spent about 15 million dollars rebuilding the Springbrook Road, Lamington National Park Road and Binna Burra Road over the past year, so in practice I suspect that's the Scenic Rim national park budget blown for the next decade or so. My understanding is that NPAQ have recently been told by the government not to bother proposing anything new wrt national parks that involves spending government money, because there ain't none.
You obviously never eaten at the Spring Creek Mountain Cafe
Thanks for the tip, I'll check it out. My Scenic Rim dining experiences have largely been similar to CBee's (cool pies and warm sandwiches) so if there's a great place to eat that's good to know.
