I'm in the same boat but I'll be waiting until the time comes that both borders are open for business. Otherwise you may be paying for an insurance policy you may not need to pay for.
From what I see when looking into one is they take all the hassle out of everything right down to your 90 day reports, VIP lane immigration so no standing in cues of hundreds. For the 5 year one it works out around 270 baht per day. Not a lot in the scheme of things. Just a big one of outlay.
But Morrison also said that he will be opening international travel between China, South Korea & NZ. The first 2 obviously are about money. Thailand has lower numbers than any of these 3 plus Oz and the grub will not allow us to travel so we can get home. It stinks as far as I'm concerned.
Those arseholes in the Australian government are saying they will probably keep the ban on international travel until 2021. I need to get back to Thailand aswell but i'm stuck in Aus.
