When landlord terminate a lease before the end of the fix term lease

with a very challenging landlord / realestate agent with on going issues which they not willing to do address. Unfortunately the agent won’t budge!

I am starting to feel anxious and hating the new apartment. I don’t feel it’s a home anymore & battling with nonsense & unreasonable agent/ landlord has taking a toll.

1. Could they terminate my contract if they found me at breach of my lease

2. Do I have to pay the landlord compensation ie loss of income, agent fee etc if the they decided to terminate my lease

3. If I agree for them to terminate my lease, how long of a period do I have before I vacate the property

4. Will my name be put on the default website as a bad tenant

its very vague as I read legislation and I would like to get advice from anyone who’s been in this situation from both tenants & landlord

thanks
