I'll go with the acreage. I had a 30-acre lot in the NSW Northern Rivers which I dearly would have loved to have kept, but the kids grown up are city dwellers now and have no interest, and you're totally correct, acreages are not good rental properties. Sell it and buy a unit in Ramsgate Sydney 👍. I don't know about Krabi, I'm a city guy, tried the provinces Phuket, Chiang Mai, Rayong, and even Khon Kaen, but always drift back to Bangkok. I'd suggest you join a Krabi expats Facebook group and post the questions there. You'll get a better idea of what kind of rents you can expect to pay.
Yes just transfer everything to your daughter's address, and ensure you register on the electoral roll for that address. Keep bank accounts, driver's licence, anything "official" which ties you to that address will suffice. My situation is very similar, I use my daughter's address, although I own the house she lives in. I'd consider keeping your residential home and renting it out, and living off the income. Once you buy in Thailand, you are tying yourself to the country. Rents in Thailand are dirt-cheap compared to Australia. Think cashflow rather than owning real estate. I have five properties in Australia, but own nothing in Thailand. The Thai Tax Office would have an insurmountable task trying to show that I am a Thai Tax Resident, other than the 180 days.
If you have a "permanent home" in Australia and visit at the frequency you mention, you will have no problems. I've done that for years. I've had dual tax residency, but Australia wins out because of the permanent home. Don't always listen to the "tax experts", I find it's best to enquire with the relevant tax authorities who will give advice and references free of charge.
Best to keep property ownership in Australia and use the income to fund your Thailand lifestyle, which is what I do. Retain your Australian Tax Residency so you will not be liable for taxation in Thailand. Don't even think about buying properties in Thailand
The ETA launch has been delayed past the original December 1, 2024 timeframe. Additionally, the Ministry of Tourism and Sports plans to introduce a THB 300 Thai Travel Tax, pending Cabinet approval in January 2025. This tax, requiring pre-arrival online registration and payment, may affect the ETA timeline.
I'm just saying you will most probably be asked to explain where it came from and where it went. Any transactions over 50k are reportable. I guess if you just say "it's a fake payment to get a dodgy visa extension" you'll be right! 😆
