800K Thb each and you need to maintain it for 2 months before and three months after extension and then never let it go below 400K for the rest of the 12 months
I’d keep things minimal My parents just moved to CM with normal luggage and purchased everything they needed ( furniture, electrical, kitchen etc) once they arrived
My mum did take some of her favourite kitchen things and my dad took a huge amount of classical music cds but they didn’t ship anything
As for your birds I have no advice but be aware animals are not easily able to return to Australia
