Thanks Mike for your help . Im based in Phuket and still on my original O-A ( issued in Sydney ) of 15 years. Well , WAS , its now expired , and tickets to PPenh for tomorrow already bought. This will be my first overstay ( 3 days ) , and I will try to re-enter by flight to Bkk on 30 day Visa Exempt , which , I believe is now 45 days. ( BTW , How annoying is that pop up on the right here while you type ! )
