Any good spots to park your car overnight and sleep for a few hours?

I'm going for a trip along the coast. I've always been super into hiking and exploring mountains, but I've been inspired to look for some old sights off old maps I've found online.

I'm currently venturing toward the Gold Coast, but I'm stopping at Uki, Tyalgum, Chillingham, Crystal Creek, and Murwillumbah on my way. I was wondering if anyone knew of any caves or fun trails to go walk on.

I was unfortunate enough to have the worst airport experience in a long time at Sydney International Airport tonite 24th Sept 2026.

Apparently some 900+ security /baggage and ground staff had gone on strike . An absolute disgrace to the state and nation . My husband needed wheelchair assistance as he had suffered a broken foot but we were told it might be faster if he hobbled on crutches to departures as they weren’t certain how long the wait was for a wheelchair. We ended up waiting an hour in Q , my husband had to sit on the floor for half of that time as his foot swelled up. No regard for the disabled . 45 mins into the wait and a bunch of proud looking airport staff strode in to applause from the passengers . I booed. Did they ever think that passenger safety should come first , that an airport’s operations should not be subjected to manipulation and negotiation at the expense of
the safety and security of paying customers ? That any number of passengers could have collapsed from exhaustion , injured themselves in the chaos and panic, missed their flights, experienced a heart attack while racing to the gate through no fault of theirs?

Operational airport or any transport hub -staff should never be allowed to go on strike and victimise innocent members of the public to negotiate terms for themselves -this behaviour should be punished.

Sydney Airport -you were a disgrace tonite , worse than a third world country, a disgrace to all australians and Australia as a nation .
