Travelling alone

My daughter is 18 and she plans to travel for 3 months (supposedly with a friend but communication between them is minimal ) therefore she is pretty much alone .

She has booked a flight there and back - in between she will be going to various places across Asia and NZ .

She won’t be working whilst away but has saved to fund the 3 month trip !

Whilst her dad and I both feel travelling is great for broadening the kind etc , we are naturally both concerned - her safety primarily .

She reminds us that thousands go and are safe and you only hear about the bad things . We both acknowledge this , and she has told us about how travellers meet up and travel onward in groups etc .

She has been to festivals and away in Europe with friends but never for this long !

Ive suggested she do a voluntary placement somewhere to begin with that has structure but she doesn’t want the restrictions .

We have the 360 app so we can see where she is and obviously communication is great too these days with smart phones and Wi-Fi .

She’s going whatever .

BUT , what else can we advise / do ?

Anyone been through similar ?

TIA
