I'm new to this site, but also from WA, we live in the South West. Haven't been here for too long but it seems that most people like to go camping at Hamelin Bay.
We live in Nannup, it's a nice little town and not a bad base for a few nights camping whilst exploring the surrounding towns (we did that last year before moving over here). Actually that camping trip (visiting rellies in Albany) is what led us to choose Nannup as a place to live.
Our kids are going on to 4 & 6yrs, and we've just switched from a Camper trailer to tents.
Did you end up camping in April? Still planing on October?
Camping while pregnant, I don't think it's crazy, unless of course you do it too close to the due date. Either way at least the baby could have an exciting birth story
