I'm not entirely sure anymore it was the 3rd or 4th entry which was denied, also got a fresh passport already

the reason was i've been to Thailand with that Stamp over 90 Days in a 6 month Period that's like 2 years ago

i think thats not true i was rejected once when i had 3 in a row in a shorter time period using it with the 30 day extension from the Immigration.

i already booked my fly back to Thailand and I'm also traveling with my gf (thai) and my mum so it's a bit difficult to take a stop in Australia. It would be completely fine if i could get that 30 day stamp at the Airport with the option to extend it another 30 days at the Immigration. The thing is just that i have read I'm only eligible for that Stamp if i wasn't in Thailand for less than 3 Months in the last 6 Month Period.
