Lately i did meet a guy from Argentina who only got a 30 days visa exempt stamp. He did not know about the 90 days bi-lateral agreement and did not check/ask about it at the entry immigration. Always good to immediately check your stamp. Immigration officers can make mistakes.
If i want to rent a new condo i always mention the mandatory TM30 reporting in my talks with the owner/agent. I tell them I need this report to be done. Mostly they do it. But probably wouldnt have done it without my demand.
One advise. Get a proper longstay visa not being a volunteer or education visa. If you have money then buy a Elite Visa. Otherwise you will be or are already redflagged and refused re-entry in the future.
