I live in TC and delivered at the Matilda. Because it is considered 'far', the midwives did not leave it to the last minute to let me come in. As soon as there was a bloody show (before full blown contractions), I was asked to come in. My water broke at the hospital and the full blown contractions started there too.
It took us 30 minutes to get there by car (using the Western Tunnel).
I am meeting another mum (who will deliver on the island) on Wednesday at PC if you're up for a cup of tea (and a discussion). We have a car so I've also offered to help out if there is an emergency in the middle of the night.
You could call the services of Happy Taxi (who will take you there) 24/7. There is no need to move to the Island.
Cheers!
