I would like to ask some advices. My bf and I rented a house with a landlord . And my bf has agreed with our landlord verbally that we will sub rent the spare rooms. so on 3rd February (Tuesday) , we found someone to move in our house, we said to him free rent up to Friday but he needs to pay the two weeks rent and bond first to hold the room. He did the transfer but until yesterday (4 days have gone) and we didn't receive the payment yet, so I started to worried and asked about the guy and he kept didn't show me the receipt. And tonight I talked with him again on Facebook as currently I am not in australia, I asked him to show me the receipt and pay us one week rent in cash first, then he told me he won't have any cash until next tuesday, so I said maybe this is not the place for you. Then he started to change his attitude, he warned me there is no rental agreement signed between us (actually I kept asking my bf to sign it but he just ignored it) , and he even asked me to give him the copy of agreement with our landlord that we can share our house with someone otherwise he can take legal action. And he even warned me to give him back half of the bond by 10am tomorrow .and he kept saying now to me he can't show me the receipt to avoid financial fraud.
This is really a terrible experience to me, I am scared and I don't know what is the best way to kick him out of the house now? I do think he can't really take legal action to us as he really failed to pay the rent on time. But He has our keys I am scared in the future he will do something to harm us.
