Renting in Victoria without a signed Tenancy Agreement. "ADVICE NEEDED"

I have been paying rent at a property in Melbourne for over a year now but feel it is now time to move on, however I just realised that I never actually signed a lease agreement. I filled out a tenancy application and filled a condition report, I also paid bond and filled out a bond transfer to have it put into my name but this never went into effect.

My question is that if I send through my notice that I intend to leave will I have 28 days, or will my landlord be able to kick me out right away because there is no lease.

I do have proof of rental payments and email correspondence to show that I have been living and paying rent here, will I have the right to 28 days? and will I be able to get my bond back?

I am not wanting to take any action at the moment, I am just trying to get an understanding of my rights before before making any decisions.

Would greatly appreciate any advice
