Personally, I wouldnt, but have lived 'remote' so it doesnt appeal as stongly to me especially if pregnant - but it would if Id never been! Awesome experience. The only thought I would have would be in regards to the possible exposure to infectious diseases that could impact your pregnancy, especially in a remote Indigenous community where there are *generally* lower rates of vax and close contact with others means higher chances of disease (chickenpox, german measles, rota & other virus'). If you have never been North or remote, the tropical climate can wreak havoc on your body - usually your bowels! (although you are coming in the dry season). Its a tough one. If the worst happened you would have access to the community clinic with facilities.
Would the opportuntiy present again some other time?
