Mummabear, Nanango is about 4ish hours from the Gold Coast.

Katstribe, pitty you couldn't stay closer to Caboolture around the time bub is due because the maternity unit there is meant to be fantastic.
If your last few labours have reduced by about an hour each and you last one was 4 hours, your next one will probably be 3 hours of less! Why don't you make your way to the hospital when you are in labour then perhaps when you get there you could try to walk around the grounds for a bit or find somewhere compfy to rest and only head into the labour ward when you think all of the action is about to start. At least this way, you might feel a little more secure as the hospital is right there so medical help is never far away. And if you are practically fully dilated when you head into the birthing suites, then bub will probably be born before the Ob even comes to see you.

I wish you all the best
